A 23-year-old man presented with right eye blurred vision; he was diagnosed with acute posterior multifocal placoid pigment epitheliopathy (APMPPE), and his symptoms resolved with prednisolone. Two months later, he developed a right arm weakness that resolved after 3 weeks. MR scan of brain identified changes suggesting multiple sclerosis, with four hyperintense FLAIR lesions; there was contrast enhancement of two lesions and no diffusion restriction. Cerebrospinal fluid showed mononuclear pleocytosis. We eventually diagnosed these as APMPPE-associated CNS lesions. APMPPE is a rare inflammatory chorioretinopathy that rarely can resemble multiple sclerosis clinically and radiologically.
