The present study was conducted with the following aims-To evaluate efficacy of CT in evaluating orbital diseases, To determine the site and extent of tumor and aid in decision making for treatment modality including surgery whenever necessary, To evaluate the orbit in patient clinically suspected to have orbital pathology, To detect, localize and characterize the lesion, To establish extent of...

BACKGROUND Orbital rhabdomyosarcoma (RMS) in childhood has an excellent survival rate after chemotherapy and radiation, and mutilating surgery can often be avoided. CASE REPORT As a rarity we present an unfortunate disease course in a child suffering from orbital embryonal RMS which did not enduringly respond to multimodal therapy including local excision and exenteration orbitae. After short...

An unusual case of orbital tumor with high renin content and severe hypertension is described. The patient was a 15-year-old girl with juvenile hypertension (200-140 mmHg) associated with right exophthalmos and hypokalemia. The patient showed extremely high levels of plasma renin activity and plasma aldosterone concentration. No difference was present in plasma renin activity from either side o...

Schwannomas of the orbit are very rare benign neoplasms. Intraorbital cystic schwannomas originating from the frontal nerve are even rarer, with only 1 case reported to date. This is most likely due to the fact that, in most cases, the origin of the orbital schwannoma cannot be identified intraoperatively. The nerve origin is usually speculated from histological examination of the specimen and ...

background and objective: inflammatory pseudotumor  is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. the aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inflam...

BACKGROUND Ocular melanoma is a rare but often deadly malignancy that arises in the uvea, conjunctiva, or orbit. Uveal melanoma is the most common type, with conjunctival melanoma being the second most frequently observed. Melanoma accounts for 5-10% of metastatic or secondary orbital malignancies, but only a minute proportion of primary orbital neoplasia. The aim of this study was to character...

PURPOSE To report a case of a 29-month-old male with familial, bilateral retinoblastoma with orbital recurrence following aggressive laser treatment. METHODS This is a retrospective case report of a single patient. RESULTS A 3-week-old male was diagnosed with familial, bilateral retinoblastoma (group D OD, group A OS), and treated with 6 cycles of systemic chemotherapy and laser treatment. ...

purpose : to present a case of orbital cellulitis secondary to dacryocystitis case report : a 48-year-old postmenopausal lady was referred with a prominent proptosis of the right eye in addition to external ophthalmoplegia. she had one year history of lacrimation. orbital computed tomography (ct) revealed an extraconal infiltration near the medial and inferior orbital wall consistent with orbit...

To our knowledge, we report the first case of an extraconal orbital cystic schwannoma in Brazilian literature. The tumor grew slowly and progressively and was associated with minimal eccentric proptosis and diplopia. The radiologic study (orbital computed tomography) revealed a rounded, encapsulated, and extraconal cystic mass in the superior medial region of the right orbit in the supraorbital...

BACKGROUND This report describes a recurrent orbital glomus tumor in an Asian patient. CASE PRESENTATION A healthy 50-year-old Korean man had progressive right exophthalmos and a soft mass on his right lower lid for 6 months. We evaluated the mass using CT and MRI, and performed excisional biopsy and pathologic examination. Pathologically, the mass was a glomus tumor. Although proptosis of th...
