An orbital tumor refers to any tumor located in the orbit, which is the bony socket in the front of the skull that contains the eye. The socket is a complicated structure that includes the eye itself along with muscles, nerves, blood vessels, and connective tissue Individual Orbital Tumors Adult Patients Idiopathic Orbital Inflammation/Orbital Pseudotumor This is a challenging disease to diagnose with certainty, since it is a diagnosis of exclusion. There is no sex predilection, with peak incidence between the fourth and sixth decades Orbital tumors may arise from Schwann cells, cells in the sheaths that cover nerves. These usually benign tumors, called neurofibromas and schwannomas, can occur on any nerve in the area except the optic nerves, which lack Schwann cells. Another relatively common benign neurological tumor in this area is the optic glioma, a tumor that arises.
An individual experiencing symptoms of an orbital tumor is likely to consult either their primary physician or an eye doctor first. An ophthalmoscope (the handheld device your doctor uses to look into your eyes) allows a view into the back of the eye and reveals details that may suggest the presence of a tumor What are they? They are tumors that appear in the tissue around the eye, in the orbital cavity. The orbit is a cavity formed by the bones that contain the eye, the muscles that move it, the optic nerve, veins, nerves and fat that fill the existing space.. The tumor may originate in any of the orbital structures
. The Surgery. Surgery for orbital tumors is individualized to the patients particular tumor and location of the tumor. Orbital surgery is most commonly performed under general anesthesia as an outpatient or a short inpatient stay An orbital tumor is an abnormal growth that forms around the eye socket that needs to be examined. Because it's such a small and sensitive space, even tiny growths in the orbital area can be extremely problematic and require medical attention. The sooner an orbital tumor is looked at, the less likely it will be to cause damage to the area An orbital tumor refers to any tumor located in the orbit, which is the bony socket in the front of the skull that contains the eye.These tumors may also be either benign or malignant, and may arise primarily from the orbit or may metastasize from elsewhere in the body
What causes orbital tumors? Orbital tumors are named by where they first developed. These growths can be either primary (meaning the tumor originated in the orbit) or metastatic (meaning the tumor comes from the spread of cancer elsewhere in the body). When primary orbital tumors develop, their cause is often unknown The term orbital tumors includes diverse benign or malignant space-occupying lesions of the orbit, often leading to dystopia of the eyeball, motility disturbances, diplopia, visual field defects, and sometimes a complete loss of vision. Removing these tumors in a limited surgical field is challeng Orbital Tumors (Eye Tumors) The orbit is the bone housing of the skull that provides structure and protection to the eyeball. It is about two inches deep and lined with muscles, fat, blood supply, nerve supply, and contains the eyeball. Any type of tumor that develops in the tissues of the eyeball or surrounding the eyeball is an orbital tumor
Orbital Cancer. In order to begin to fully understand orbital cancer, it is important to understand the anatomy of the region. The orbit is the part of the face that houses the eye. It includes the eye socket and all of its parts, such as muscles, nerves, lymphatics, blood vessels, the structures that produce tears, and the eyelids. The brain. An orbital tumor is a growth that can arise from any of these structures. Occasionally, a tumor may develop in the brain or sinuses and invade the orbit. In some cases, having cancer elsewhere, such as in the breast or prostate can lead to the metalization of tumors to the orbit. Who Needs Treatment for Orbital Tumors Children tend to have orbital metastasis from neural embryonal or sarcomatous tumors, while metastases in adults tends to arise from carcinomatous tumors. The most frequent metastases to the orbit are from breast, lung, prostate, melanoma, carcinoid, GI, renal cell, neuroblastoma, and rhabdomyosarcomas 
Orbital tumors can originate directly in the eye socket, and these are known as primary tumors. If the cancer originates in a different location before spreading to the orbit, then it is called a secondary tumor or metastasis. Orbital tumors can occur in both children and adults. Types of Orbital Tumors Orbital tumors represent approximately 0.1% of all tumors and approximately 18% of all orbital diseases. Neoplasms of the orbit may be primary, secondary (infiltration from adjacent structure), or metastatic (from distant structures)
An orbital tumor refers to any tumor located in the orbit. The orbit is a crowded space, so any tumor in it can cause serious symptoms and functional problems with the eye. Orbital tumors can be primary, meaning they originate in the orbit. They can also be secondary, meaning that they invade the orbit from the adjacent paranasal sinuses or face Orbital Tumors Benign. There are several tumors of a benign nature that can arise in the orbit. Although they don't pose a threat to life prognosis, they can cause other problems such as vision loss and displacement of the globe. Some of these tumors include cavernous hemangioma, optic nerve sheath meningioma, sphenoid wing meningioma. Introduction. The orbit is a small anatomical space with a wide range of important structures within. Tumours and tumour-like lesions often arise from these orbital contents and are a common indication for the radiological evaluation of the orbit in both adults and children The cause of primary orbital tumors is unknown. In children most orbital tumors result from developmental abnormalities. When visual loss or deterioration occurs with an orbital tumor, it may result from either mass effect, compromise of the vasculature to the optic apparatus as a result of the tumor, or invasion of the optic nerve by the tumor Among the known causes for orbital and ocular tumors in children are the following: Developmental abnormalities such as an overgrowth of benign (e.g., dermoid cyst, hemangioma) or malignant (retinoblastoma) cells. Cancer that has spread from another part of the body. Problems with blood vessels, including reduced blood flow or overgrowth of.
. It is a chronic condition that acts much like a brain tumor. Unlike a tumor, however, the pseudotumor does not spread and does not invade nearby tissues Orbital surgery and debulking is indicated only in selected cases where the tumor is small, well-circumscribed, and easily accessible, or where it threatens vision or for palliation in cases where the tumor causes extreme proptosis and pain (Shields, OPRS 1988)
Nonosseous, extraocular orbital tumors are uncommon in children and represent a different histologic spectrum than is seen in adults. Most of these lesions are mesenchymal in origin. The most common mesenchymal tumor of childhood is rhabdomyosarcoma, which may arise in or invade the orbit in young children Orbital tumors can be classified based on origin: 1) Primary lesions, which originate from the orbit itself; 2) Secondary lesions, which extend to the orbit from neighboring structures and include such lesions as intracranial tumors and tumors of the paranasal sinuses that, by contiguity, extend to involve the orbit; an Orbital Tumors. 2nd ed. Lippincott-Raven; 1980. Holmes S, Hutchison I. Reconstruction of the orbital floor after its removal for malignancy. Br J Oral Maxillofac Surg. 2001 Apr. 39(2):158-9. . Huh WW, Beverly Raney R. Orbital metastasis in patients with rhabdomyosarcoma: case series and review of the literature. J Pediatr. An orbital tumor is any abnormal tissue growth in this area. Most orbital tumors are noncancerous. Many types of orbital tumors can push the eye forward and cause it to bulge. The most common orbital tumors in children occur in blood vessels or as bone cysts. In adults, the most common orbital tumors occur in blood vessels
. There are over 1500 different tumors that can affect the orbit. The majority of these tumors are benign. These tumors cause problems because of their location and proximity to vital structures and organs including: the eye, the muscles that move the eye, the lacrimal gland, the nerves and vessels of the. Idiopathic orbital inflammation (IOI), also known as orbital pseudotumor and non-specific orbital inflammation, is an idiopathic inflammatory condition that most commonly involves the extraocular muscles.Less commonly there is inflammatory change involving the uvea, sclera, lacrimal gland, and retrobulbar soft tissue.. The exact etiology is not known but an association with many inflammatory.
Orbital cellulitis causes relatively more lid swelling and less proptosis; Conjunctivitis causes more engorgement of conjunctival vessels and no proptosis; Contact dermatitis affects only lids and surrounding facial skin; Stye causes focal swelling and tenderness mainly affecting one lid; Dacryocystitis causes focal swelling and tenderness of nasal portion of lower lid, where lacrimal sac lie Benign orbital tumors represent a broad spectrum of tumors (Chapter 86). In addition, orbital inflammation and infection may clinically simulate an orbital neoplasm (Chapter 89). In a recent survey of 1264 consecutive patients with suspected orbital tumor referred to an ophthalmic oncology center, 64% of the lesions were benign.
Orbital tumors in children are very rare and radiologic image, as magnetic resonance, is extremely important for correct diagnosis. We report six cases of different diagnosis of orbital tumors, comparing their images and clinical aspects. Radiologic images are essential for determine specific diagnosis in most cases of pediatric orbital pathology Orbital tumors can grow anywhere in the orbit or else can penetrate the eye orbit from the surrounding structures. The tumors can originate in the nasal cavity, the paranasal sinuses or the brain cavity. Sometimes, the tumors can also grow immediately on the bones and then intrude in the eye orbit area. The various types of orbital tumors can be: Orbital Tumor Tumors are abnormal growths of tissue that can be either benign (non-cancerous) or malignant (cancerous). Tumors situated on the orbit, or eye socket, should be evaluated and treated as soon as possible. A cancerous tumor requires immediate medical attention. Symptoms of an Orbital Tumor A tumor can cause pain or damage to the Orbital Tumor Removal Read More Â Orbital tumors are a relatively rare and challenging group of tumors. Thorough knowledge of the anatomy of the extraocular muscle cone, key neurovascular structures is of paramount importance and helps to classify an orbital lesion and choose an ideal approach. Tumor location rather than tumor type determines the type of approach selected

November 1, 2013. Drs. Gionfriddo and Aaroe provide an overview of common orbital diseases in dogs and the best approaches for diagnosis and treatment. An 8-year-old spayed female miniature poodle was presented to a veterinary clinic in Colorado with the complaint of a.
Lymphoproliferative tumors of the ocular adnexa encompass a wide spectrum of lesions that range from reactive benign hyperplasia to malignant lymphoma. Ocular adnexal lymphoma (OAL) is a localized form of systemic lymphoma affecting the orbit, the lacrimal gland, the lids and/or the conjunctiva. It comprises 6-8% of orbital tumors, and 10-15% of adnexal lesions Surgical Management of Orbital Tumors Surgical Management of Orbital Tumor The details of surgical approaches to orbital tumors and pseudotumors are discussed elsewhere (1,2). Enucleation is discussed in the Atlas of Intraocular Tumors and is not covered here. Illustrated and briefly described here are the indications and techniques of orbital fine-needle aspiration biopsy (FNAB), conjunctiva Orbital tumors are growths that develop anywhere in the orbit and can be benign or malignant. Because of limited space within the orbit, even small tumors press upon the eye structures causing symptoms such as forward bulging of the eye (proptosis) and vision issues. Depending on the tumor type, it may occur more often in children or adults Howard GR, Nerad JA, Carter KD, et al.

Orbital imaging in cases of RB-associated orbital pseudocellulitis is most commonly misinterpreted as extraocular tumor extension due to soft tissue swelling around the globe . The preferred treatment protocol for cases with extraocular tumor extension versus those with intraocular RB may differ Orbital hematoma is an uncommon but serious complication of sinus surgery. Appropriate perioperative attention may minimize risk, but early diagnosis and appropriate management are crucial to. The cause of most orbital tumors is unknown. Most orbital tumors in dogs and cats are malignant. Examples of primary cancers include the osteosarcoma (from bone), fibrosarcoma, chondrosarcoma (from cartilage), meningioma of the optic nerve, rhabdomyosarcoma (from muscle), mast cell tumor, neurofibrosarcoma (from nerves) Tumors are abnormal growths that occur when cells begin to expand out of control. They can be either benign (harmless) or malignant (cancerous). Orbital and adnexal tumors develop from tissue, such as from muscle, nerve, or skin around the eyeball. The orbit - also known as the eye socket - consists of the tissues surrounding the eyeball Orbital Diseases and Tumors The orbit (or orbital bone) is the socket that houses the eye and all of its supporting structures. Orbital tumors can emerge within the eye socket or form in adjacent sources, such as the eyelid, paranasal (the space that surrounds the nasal cavity), sinus or intracranial compartment
The proptosis direction is usually downward because the majority of the primary orbital tumors develop in the upper half of the orbit. Lateral displacement, on the other hand, is usually seen as a result of secondary orbital lesions , such as a mucocele or squamous cell carcinoma, originating from the ethmoidal sinuses Chemosis of varying degrees is also a common finding in orbital tumor patients (Figure 6.1). Fully dilated indirect ophthalmoscopy should be performed on every patient because many orbital diseases cause a wide variety of funduscopic changes, which may provide clues regarding the location, size, and the nature of the orbital pathology.4 The. The physicians in the Eye/Orbital Cancer Program use several specialized techniques to treat ocular tumors, including research and the use of clinical trials. Individual care plans can include one or more treatment methods, including laser surgery, external beam radiation, cryotherapy (destruction of cancerous tissue by freezing) and chemotherapy
Orbital tumors can cause blindness and other vision problems since they grow right in the bony socket that holds the eye as well as the nerves, muscles and connective tissues that control eye movement. Some of the more common orbital tumors include: Osteomas; Sarcomas According to Shields (1998), gliomas account for 1-2% of all orbital tumors, while according to Baert (2006), up to 4%. Women are affected more often than men (3:2). 30-40% of patients with gliomas have manifestations of NF I, and 15% of patients with NF I have an optic nerve glioma. Only gold members can continue reading After enucleation orbital recurrence developed within 14 days. No anti-tumor treatment was given and the child died at the age of 4 weeks. The histopathological and cytogenetical analysis of the tumor is presented. The tumor was diagnosed as a retinoblastoma but we could not exclude the possibility of a neuroblastom Orbital Tumors. The acoustic (eighth cranial) nerve includes branches that mediate the sense of balance and head position (the vestibular nerve), as well as hearing (the cochlear nerve). Acoustic neuromas are benign tumors that arise from the vestibular portion of the acoustic nerve. Surrounding each nerve fiber are Schwann cells that form a. Karcioglu's Orbital Tumors covers all phases in the diagnosis and treatment of orbital tumors -- from the initial evaluation of the pathology using both imaging techniques and surgical biopsies, to the medical and surgical treatments and follow-up management plans. The practical, concise approach allows a format which makes the text useful for all ophthalmic specialists who treat tumors On imaging, there was a right retro-orbital tumor for which an excision was performed. Intraoperatively, a well-encapsulated tumor within the cystic component containing clear fluid was noted and the relation of this tumor to the nerve could not be clearly ascertained. On histology, the excised specimen revealed a cellular neoplasm consisting.
