A case of exophthalmos due to zygomatic mucocele in a puppy with ipsilateral segmental maxillary atrophy is reported. A 7-month-old, mixed breed, male dog suffered the sudden-onset of unilateral painful exophthalmos and a gradual swelling of the right temporal region. A compressing, right retrobulbar mass was observed by ultrasound. Computed tomography revealed a large multiloculated cyst-like ...

A 3-year-old Filipino girl presented with progressive left-sided ptosis and proptosis after resection of a superomedial orbital tumor 2.5 years ago. She had been followed with serial MRI, which demonstrated interval growth of a recurrent lesion. Repeat resection was undertaken via an eyelid-splitting anterior orbitotomy. The patient's pediatric oncologist and sarcoma specialist did not recommen...

Cavernous haemangioma(CH) is mostly intraconal, single and unilateral in location. A 32 year old female presented with painless progressive growth near the inner canthus of right eye along with swelling of right upper eyelid and superomedial quadrant of the right orbit for five years. MRI showed lesions involving the preseptal space and extraconal compartment of the orbit at the superomedial as...

Intraorbital schwannoma is a rare tumor which accounts for about 1-2% of all neoplasms of the orbit. Orbital schwannomas most commonly arise from the sensory branches of the trigeminal nerve. On the other hand, intraorbital abducens nerve schwannomas are extremely rare, with a search of the English literature identifying only four cases of intraorbital abducens nerve schwannoma. This is the 5th...

BACKGROUND Highly aggressive Burkitt lymphoma (BL) with rapidly progressive painful proptosis of the right eye is rarely encountered. CASE PRESENTATION A 31-year-old Caucasian female presented with rapidly progressive painful proptosis of the right eye and poor visual acuity. Diagnostic Computer tomography, magnetic resonance imagining and angiography, identified an oval-shaped mass on the me...

Hydatid cysts rarely appear isolated in the orbital cavity without involvement of other organs. The cysts are usually located in the retrobulbar region, and may be extraconal or intraconal. Herein we present a case of primary orbital cyst hydatid that is adjacent to the medial rectus muscle and optic nerve in the intraconal space and the difficulties during the surgical and medical treatment pe...
