Pulsatile Proptosis due to Intraorbital Meningocele

Pulsatile Proptosis due to Intraorbital Meningocele

We present a case of a 79-year-old man with a non-symptomatic pulsatile proptosis of the left eye. Magnetic resonance imaging revealed a meningocele into the left orbit due to an osseous defect in the orbital roof.

Unilateral proptosis due to cerebellar stroke.

Orbital Meningoencephalocele and Pulsatile Proptosis: A Rare Entity

Orbital roof defects are rare congenital osseous abnormalities that cause protrusion of intracranial contents into the orbit, resulting in a condition known as the orbital meningoencephalocele, a rare cause of pulsatile proptosis. We present a case of a 25-year-old lady, presented to us with complaints of left frontal headache, left eye protrusion and double vision from the left eye for the pas...

Marrow suppression with myelodysplastic features, hypoerythropoetinemia, and lipotrophic proptosis due to rosiglitazone.

Thiazolidinediones (TZDs) are frequently used pharmacotherapeutics for type II diabetes mellitus, which exert their effect through peroxisomal proliferator agonist receptor (PPAR) mediated increased insulin sensitivity. TZDs are known to cause marrow suppression and to stimulate adipogenesis. Case and cohort studies show TZDs worsen thyroid-associated orbitopathy. We present a case consistent w...

Intraorbital amyloid.

Several reviews of ocular amyloidosis have emphasized its origins in the conjunctiva and lid (Halasa, I965; Stansbury, I965; Smith and Zimmerman, I966). The occurrence of orbital amyloid has been considered extremely rare, its pathogenesis speculative, and its place in the spectrum of diseases associated with amyloid deposition uncertain (Groniowski, Bernardczykowa, and Norn, I965; Howard, I966...
