The patient experienced worsening lower-extremity weakness, scoring 1 of 5 to 2 of 5. Angiogram found normal brain vasculature, but showed 1 lumbar spine vessel to be occluded.
Echocardiogram demonstrated an ejection fraction of 60%, with atherosclerotic changes of the aorta. Electroencephalogram (EEG) revealed diffuse cerebral disturbance with slowing. Computed tomographic (CT) scan of the chest, abdomen, and pelvis showed enlarged adrenal glands. A colonoscopy demonstrated 2 polyps (tubular adenomas), which were removed.
At this point a brain biopsy was performed (Figure 2).
Microscopic examination of frontal lobe biopsy demonstrates small blue cells filling a parenchymal arteriole (black arrow).
Based on the findings in Figure 2, what is your diagnosis?
