Distal hyperintense vessels (DHV) on MRI FLAIR sequences in acute brain ischemia are thought to represent leptomeningeal collateral flow. We hypothesized that DHV are more common in acute stroke patients with perfusion-diffusion weighted mismatch (PDM) than in those without. ⋯ DHV may be a surrogate marker for PDM in patients with hyperacute ischemic stroke.

The Cavum Septi Pellucidi (CSP), Cavum Vergae (CV) and Cavum Veli Interpositi, are anatomical variants located in the midline of the brain. It is important to identify these conditions to distinguish them from other entities that may require treatment. In this paper, our purpose is to describe MR and CT findings of CSP, CV and Cavum Veli Interpositi, explaining the differential diagnosis.

Dural arteriovenous fistula (DAVF) of the anterior condylar canal is a rare subgroup of posterior fossa DAVF. Successful treatment of this DAVF requires an accurate image diagnosis and the knowledge of the anatomy of the anterior condylar confluent. We present the imaging features of angiography and MR angiography of a 54-year-old man, who presented progressive right synchronous tinnitus due to a DAVF of the anterior condylar confluent, successfully treated by transvenous embolization.

To assess the involvement of basal ganglia and thalamus in patients with amyotrophic lateral sclerosis (ALS) using diffusion tensor imaging (DTI) method. ⋯ The increased MD in basal ganglia and thalamus and decreased FA in globus pallidus and thalamus are indicative of neuronal loss or dysfunction in these structures.
