purpose : to report a patient with orbital pseudotumor masquerading as orbital cellulitis case report : a 42-year-old woman was referred to orbit and oculoplastic clinic with 6 days history of left orbital pain, proptosis, lid edema and fever. clinical finding included severe lid edema, chemosis, conjunctival injection and severe restriction in extraocular motility. she was diagnosed as orbital...

ocular involvement is seen in approximately 25% of patients with sarcoidosis. uveitis is the most common ocular manifestation, but sarcoidosis may involve any part of the eye. orbital manifestations of sarcoidosis are uncommon with few series in the literature. a 65-year-old woman presented with redness of the right eye and painless, unilateral eyelid swelling. orbital scanning revealed mass in...

Orbital inflammatory pseudotumor is an infrequent lesion that may mimic malignancy and may be associated with autoimmune disease. Orbital pseudotumor is in the differential in any patient with an orbital mass, especially in the setting of chronic infection or immunosuppression. This HIV-positive patient presented with chronic sinusitis and orbital pseudotumor.

Inflammatory pseudotumor most commonly occurs in the orbit and produces orbital pseudotumor, but extension into brain parenchyma is uncommon. We report a case of inflammatory pseudotumor involving sphenoid sinus, cavernous sinus, superior orbital fissure, orbital muscle, and intracranial extension into left temporal lobe producing right hemiparesis and wernicke's aphasia. The patient improved c...

Idiopathic orbital pseudotumor is a benign, noninfectious, and nonneoplastic disease with unknown cause. It is the third most common orbital disease after thyroid orbitopathy and lymphoproliferative disorder. Idiopathic orbital pseudotumor is extremely rare in pediatric age group and may cause real diagnostic problems. This paper describes a 4-year-old girl who presented with sudden ptosis in t...

BACKGROUND An orbital pseudotumor typically presents with periorbital pain, cranial nerve palsies and proptosis. Although visual deterioration is not unexpected in this pathology, its presentation solely with visual loss is unusual. CASE REPORT In this short report, we summarize a case of orbital pseudotumor which presented solely with a decrease in visual acuity, and discuss the clinical and...

PURPOSE To report an unusual case of spontaneous late leakage of filtering bleb in a patient with orbital pseudotumor. METHODS Single case report. RESULTS A 53-year-old woman developed spontaneous leakage of bleb in her right eye 23 years after trabeculectomy with application of mitomycin-C (MMC). Two weeks later, her symptoms were blurring of vision, increasing redness, and dull ocular pai...

Ophthalmologists in the early 1800s made an interesting observation that several patients with presumed orbital tumors showed spontaneous improvement without any treatment. Until then proptosis was considered as prima facie of orbital neoplasm. Panas coined the term “pseudoplasm” for these puzzling cases. Birchfield in 1930 used the term orbital pseudotumor for such cases. Improvements in diagn...

Fifteen patients with clinical presentations compatible with idiopathic inflammatory orbital pseudotumor were examined by CT and MR imaging to determine if MR could add specificity to the CT appearance of this entity. MR was performed on a 1.5 T system, using surface-coil and head-coil techniques. Idiopathic pseudotumor was confirmed in nine patients on the basis of response to steroid therapy ...
