RESUMO
Human immunodeficiency virus (HIV) infection can result in ischemic stroke via several mechanisms, including opportunistic infection, vasculopathy, cardioembolism, and coagulopathy. HIV-vasculopathy is related to endothelial dysfunction, stenosis and aneurysm formation, infectious vasculitis, dissection and accelerated atherosclerosis during highly active antiretroviral therapy (HAART). We represent a case of HIV infection manifested as an acute ischemic stroke attack. After 4 months during HAART, our patient experienced a recurrent ischemic stroke with progression of middle cerebral artery stenosis.

Crossed cerebellar diaschisis (CCD) is known to be due to a contralateral supratentorial lesion decreasing blood flow and the metabolism in a cerebellar hemisphere. Arterial spin labeling (ASL) is an imaging technique that utilizes arterial blood water as a tracer for quantifying the regional cerebral blood flow in magnetic resonance imaging (MRI). This case was a patient with simple partial status epilepticus (SPSE) and CCD confirmed by ASL-perfusion MRI. Controlling the SPSE resulted in improvement of CCD being observed in the follow-up ASL-perfusion MRI.

A cavernous angioma (CA) and a developmental venous anomaly may consist a mixed vascular malformation (MVM). Two bleeding foci were observed in a MVM of a man with epilepsy. The hemodynamic association between the two foci was not clear. An advance of neuroimaging may enhance the susceptibility of detection of MVMs. We should consider a MVM when a daughter bleeding focus occurs near the main bleeding focus associated with a CA.
