Abstract

PURPOSE: Orbital hematic pseudocyst is the localized accumulation of organized blood-breakdown products within a fibrous capsule, and is known to be typically located subperiosteally. We report a case of orbital hematic pseudocyst in the intraconal space.
METHODS
A 51-year-old man visited our clinic, complaining of injection and bruise of his right eye one month before. On the orbit MRI, a mass assumed to be benign was detected in the intraconal space of his right orbit. After several months of follow-up, a decrease of visual acuity and visual field defect were detected in his right eye. Excision of the mass was done through lateral and medial orbitotomy.
RESULTS
Histologic examination showed the accumulation of blood-breakdown products within a fibrous capsule, and the mass was diagnosed as a hematic pseudocyst.
CONCLUSIONS
When a well-demarcated and slowly growing mass is detected in the intraconal space of the orbit, the possibility of hematic pseudocyst should be considered.
