March 2019 — Anatomic Pathology/Neuropathology

A 52-year-old man presented with right-sided upper and lower extremity weakness. He was previously diagnosed with HIV infection, though he is not currently on antiretroviral therapy. Brain MRIs demonstrated a T2-hyperintense, non-enhancing lesion within the left posterior frontal lobe, in the region of the motor cortex.

He subsequently underwent a brain biopsy.
