Disease Location
Brain
Personal Characteristics
44 years old male
Clinical Characteristics
Two episodes of focal seizures 2 months apart involving left leg. Mild post-ical confusion. No definitive loss of consciousness. Cranial CT showed an ill-defined hyperdense lesion with a few specks of calcification in the right occipital region anteriorly. No evidence of acute hemorrhage or mass effect was seen. Digital subtraction angiography (dsa) using nonionic contrast medium revealed pial avm in parietooccipital region. The nidus measured 2 cm in size with multiple feeders from right mca and pca
Remission Characteristics
Three months later, pre-embolization angiogram showed non-filling of the avm nidus and draining veins. Patient was neurologically intact. At 6 months follow-up, the patient had no recurrence of symptoms.
Treatment & Mechanisms
Proposed Remission Mechanisms
Venous thrombosis of the dominant-draining vein.
Clinical Treatment
Anti-epileptics
