Dural arteriovenous malformation with symmetrical calcification of the basal ganglia: a case report.

Dural arteriovenous malformations associated with symmetrical calcification of the basal ganglia are rare in children. This report concerns a 22-month-old female infant who was admitted with the problem of acute onset of status epilepticus. Physical examination revealed a grade II/VI heart systolic murmur over the left sternal border, and engorged scalp veins. Neurologically, left side hemiparesis, brisk deep tendon reflexes, bilateral presence of Babinski sign and ankle clonus were present. Brain computed tomography without contrast medium showed cortical atrophy and symmetrical calcification of the basal ganglia. Brain magnetic resonance imaging showed a signal-voided tortuous structure over the right parietal region. Cerebral angiography disclosed a dural arteriovenous malformation, located over the right parietal region, which had two major feeding arteries from the branch of the anterior cerebral artery and the parietal branch of the middle cerebral artery, and had direct venous drainage into the superior sagittal sinus. The patient received craniotomy with ligation of feeding arteries. She became seizure-free, and her neurological deficits improved gradually.
