[A case of systemic lupus erythematosus associated with thrombotic thrombocytopenic purpura manifestating homonymous hemianopsia].
We report on a 35-year-old Japanese woman with systemic lupus erythematosus (SLE) in whom homonymous hemianopsia developed. In August 1987, SLE was diagnosed. In November 1987, the patient was admitted to our hospital because of severe thrombotic thrombocytopenic purpura; however, clinical symptoms improved after treatment with vincristine. In 1992, severe lupus nephritis developed but improved after steroid therapy. In February 1994, diplopia developed owing to inflammatory invasion of the orbit by acute maxillary sinusitis. Humphrey Field Analyzer perimetry revealed a homonymous quadrantic hemianopic scotoma in the lower left side. Magnetic resonance imaging of the brain revealed a small infarct lesion in the posterior pole of the upper calcarine cortex. This lesion was thought to be responsible for homonymous hemianopsia. However, the lesion was not visualized with computed tomography. Our experience in the present case suggests that magnetic resonance imaging is more useful than computed tomography for identifying lesion causing visual field disorders in SLE.
