- The authors report a case of recurrent arteriovenous malformation
(AVM), which has been completely removed and disappeared on postoperative
angiography four years ago. Initially, at the age of nine years, she presented
intracerebral hematoma. The angiography demonstrated an aneurysm and AVM
nidus located in the posterior frontal area, fed by the branches of the anterior and
middle cerebral arteries. Eleven days after the ictus, rebleeding occurred, so left
fronto-parietal craniotomy was done emergently. The hematoma and AVM nidus
with aneurysm were removed. Her postoperative course was uneventful and
postoperative angiography showed that the AVM had been completely excised.
However, four years later, sudden focal motor seizure on right leg developed.
Magnetic resonance (MR) images and angiography demonstrated that the AVM
reappeared on the previously operated region. Extirpation of the recurrent AVM was
carried out. We do emphasize a long term follow-up MR images or a repeated
angiography is essential to confirm the complete absence after excision of the AVM.
