Orbital tumors can be either malignant or benign. They arise mainly within the orbit or from an adjacent source, such as the paranasal sinus, eyelid or intracranial compartment.
Some orbital tumors can cause a bulging of the eye (proptosis) and displacement of the globe in the opposite direction of the tumor. Pain, vision loss and diplopia may be present, as well. The diagnosis is based on the examination, history and neuroimaging (CT, MRI or both), but conclusive diagnosis often requires a biopsy.
Thyroid eye disease and lymphoid tumors (lymphoma and atypical lymphoid hyperplasia) are the most common causes of proptosis.
Other tumors include vascular tumors (lymphangioma, hemangiomas), lacrimal gland tumors (benign mixed tumor, dacryoadenitis, adenoid cystic carcinoma and sarcoidosis), and growths that extend from the sinuses into the orbit (mucocele, squamous carcinoma). Metastatic cancer can also form an orbital tumor. Lastly, an orbital tumor can also be caused by infection (an abscess) or inflammation (sarcoidosis, pseudotumor).
Orbital Tumor Symptoms
Orbital tumors may put pressure on other structures within the eye, which can lead to:
- Abnormality of the pupil
- Bulging or protrusion of the eye (one of the most important signs)
- Changes to eye muscle function
- Pain (attributed to cancer in the orbital bone or nerves)
- Vision changes (double vision, blurred vision or vision loss)
Our team of specialists provides the most up-to-date evaluations using the latest diagnostic and imaging technology.
We work very closely with the departments of Neurosurgery, Interventional Neuroradiology, Neurology and Radiation Oncology, as well as the Normal Pressure Hydrocephalus Center and Skull Base Center to ensure an accurate diagnosis and the appropriate treatment for the best outcome.
