Internal capsular genu infarcts infrequently cause cognitive impairment and behavioral changes, and little is known about the underlying mechanism. Using diffusion-tensor imaging (DTI) and the fractional anisotropy (FA) index in the region of interest (ROI) and ipsilesional frontal cortex, we evaluated two patients with internal capsular genu infarction who presented with frontal dysfunction and cognitive impairment. The reported findings help to elucidate the mechanism underlying cognitive deterioration in internal capsular genu infarction.

Behcet's disease is a systemic vasculitis that is characterized mainly by recurrent oral and genital aphthous ulcers, uveitis, and skin findings. Its neurological manifestations are well recognized. Recurrent meningitis in Behcet's disease is exceptional. We describe herein the case of a 31-year-old man who presented with recurrent aseptic meningitis without any specific cause. A few years later he developed oral and genital ulcers, and uveitis. Behcet's disease should always be considered in a differential diagnosis of recurrent aseptic meningitis without viral infection, particularly in the context of multisystem manifestations.

High signal intensity on diffusion-weighted image (DWI) at the site of venous occlusion has previously been reported in cerebral venous thrombosis (CVT). The frequency and diagnostic value of these signal changes in CVT were unknown. Some authors suggest that the presence of high signal intensity on DWI in occluded veins might help diagnose CVT and suggest low rate of recanalization. We experienced two cases of CVT with high signal intensity at the site of intravascular clot on DWI.

Neurilemmoma is a benign, solitary tumor which may occur from the nerve sheath of the peripheral, sympathetic and cranial nerves. Although it occurs most frequently in the head and neck region, especially in the acoustic nerve and the vagus nerve, the neurilemmoma of the brachial plexus is rare. We have experienced a case of neurilemmoma in the brachial plexus. Surgical excision was performed by anterior supraclavicular approach. The mass was removed completely, sparing the nerve function. We report this case with literature review.
