A Case of Histological Diagnosis of Myositis in a Person Living with HIV

Abstract

We report the case of a 58-year-old male with a recent diagnosis of HIV infection admitted for progressive muscular weakness and psychomotor impairment. Cerebrospinal examination documented a mild hyperproteinorrachia, with normal cells count and reduced glycorrhachia. Brain gadolinium-enhanced MRI showed bilateral T2 and FLAIR hyperintensities in the nucleo-capsular region and irregular contrast-enhancement of the and the right putamen. The histologic analysis of a quadriceps biopsy showed several foci of inflammatory infiltrates with concomitant muscular fiber atrophy and degeneration. Scattered intracytoplasmic inclusions were observed in muscle fibers, representing the main pathological feature. A positive PCR for and a specific monoclonal antibody immunohistochemical staining confirmed the diagnosis.
