Acute posterior multifocal placoid pigment epitheliopathy and late-onset meningo-encephalitis.

A steroid-sensitive meningo-encephalopathy developed in a healthy young woman 5 1/2 years after the occurrence of acute posterior multifocal placoid pigment epitheliopathy (APMPPE). The association of APMPPE with systemic and neurologic inflammatory disorders has been well documented, but to the knowledge of the authors, this is the first report of an APMPPE patient in which there was delayed onset of the meningo-encephalopathy. The association with dermal vasculitis, nephropathy, meningo-encephalitis, cerebral vasculitis, and thyroiditis suggests that APMPPE may be one manifestation of a diffuse systemic inflammatory condition.
