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.

Transient isoniazid-induced brain lesions have rarely been reported. The lesions were in the dentate nucleus of cerebellum and thalamus. Meanwhile, the neurotoxicity of rifampin has not been reported evidently. We observed bilateral lesions in the internal capsule in a young woman after taking a combination of isoniazid and rifampin. She transiently suffered numbness in both hands, dysarthria, and left side motor weakness while taking the medication. Isoniazid may induce structural lesions in various brain areas including the internal capsule.

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.
