MRI: In the posterior cortical and subcortical right temporal lobe, there are prominent rpiginous flow voids that demonstrate enhancement and measure approximately 1.9 x 1.2 x 1.1 cm, consistent with an arteriovenous malformation. The brain parenchyma is otherwi unremarkable. Ventricles, sulci, and cisterns are normal in size and symmetric. Calvarium is normal. Orbits are unremarkable.
Angiogram: There is a 1.8 x 1.3 x 1.3-cm arteriovenous malformation in the posterior right temporal lobe. The arteriovenous malformation is supplied by arterial feeders from distal right middle cerebral artery (MCA) branches. There is superficial drainage into the superi
or sagittal sinus and right transver sinus.
The angiographic appearance of the right supraclinoid internal carotid artery and right anterior cerebral artery is unremarkable. The angiogram has normal parenchymal and venous phas. There is no evidence of high-grade focal intracranial stenosis. The left common carotid artery and right vertebral and right common femoral artery also were lected and found to be unremarkable in cour and appearance.
Diagnosis: Small right posterior temporal arteriovenous malformation.
