A gentleman aged 38 years presented with a 5 years history of a feeling off epigastric discomfort followed by automatic movements lasting for 10 minutes followed by complete recovery. He had no memory of the episode. He was diagnosed as a case of complex partial seizures which were poorly controlled with medication.
CT scan of the head showed a lesion in the right temporal lobe of the brain(yellow arrows).
MRI brain also revealed an Arterio-venous malformation in the right temporal lobe(yellow arrows)
Digital Subtraction Angiography showed that the malformation was fed by branches from the middle cerebral artery with veins draining towards the surface and into the depth.
The AV malformation was completely removed by microsurgical technique. During surgery multiple tortuous arterialized veins were fed by right first part of the middle cerebral artery. It was drained by two veins, one over the brain surface and the other towards its lower surface.
Post-operative CT scan of head showed surgical changes and the cavity left after removal of the AVM (yellow dots)
The patient recovered well and was discharged intact on long term anti-epileptic medication.
