Frosted Branch Angiitis and Late Peripheral Retinochoroidal Scar in a Patient with Acquired Toxoplasmosis

Abstract

Purpose

To report a case of acute frosted branch angiitis associated with acquired toxoplasmosis in which a late peripheral chorioretinal scar developed.

Method

Case report.

Results

A 32-year-old man without systemic symptoms presented with sudden visual loss in his left eye. Examination demonstrated frosted branch angiitis without necrotizing chorioretinitis. Serologic tests showed elevated Toxoplasma gondii-specific immunoglobulin M antibody titers. Antitoxoplasmic therapy and oral steroids healed the ocular inflammation. In a follow-up visit one year later, a peripheral chorioretinal scar was noted.

Conclusions

Acute frosted branch angiitis without focal necrotizing chorioretinitis can be a manifestation of acquired toxoplasmosis. This could be an important, and sometimes forgotten, sign of the disease.
