Perfusion-CT imaging in epileptic seizures.

Introduction: PCT is used in the diagnosis of acute neurological syndromes, particularly stroke. We aimed to evaluate PCT abnormalities in patients with acute epileptic seizures or status epilepticus (SE).

Methods: We collected patients undergoing acute PCT for the suspicion of acute ischemic stroke (AIS), who received a final diagnosis of focal seizures or generalised seizures with a post-ictal deficit, with or without concomitant AIS.

Two brothers with atypical syndactylies, cerebellar atrophy and severe mental retardation.

Two brothers with a combination of atypical syndactylies, cerebellar atrophy and severe mental retardation are described. These cases share important features with the group of craniodigital syndromes and could represent new occurrences of Filippi syndrome. Cerebellar atrophy may represent a yet unreported finding in this syndrome.

Eosinophilic aseptic arachnoiditis. A neurological complication in HIV-negative drug-addicts.

The finding of an eosinophilic aseptic meningitis in IV drug abuse is usually suggestive of an opportunistic infection or an allergic reaction. However, HIV-negative patients are at lower risk for developing these complications. Two young HIV-negative patients, with previous intravenous polytoxicomany, developed cystic arachnoiditis over the spinal cord associated with eosinophilic meningitis.
