Cerebral aneurysms arising on the peripheral posterior inferior cerebellar artery (PICA) are rare. Here, we present a unique case of arteriovenous malformation (AVM) with pedicle aneurysms arising on the peripheral PICA and recruited by meningeal supply. A 67-year-old woman presented with subarachnoid hemorrhage. Cerebral angiography revealed two saccular aneurysms on the peripheral PICA, which formed an abnormal arteriovenous shunt adjacent to the transverse sinus. The shunt was also fed by the ipsilateral superior cerebellar and contralateral posterior meningeal arteries. The proximal aneurysm was larger and deep seated while the distal aneurysm was smaller and located superficially. The patient underwent coil embolization of the proximal aneurysm followed by microsurgical trap of the distal aneurysm and resection of the arteriovenous shunt lying superficially in the cerebellar hemisphere. The shunt was histologically verified as AVM. Staged approach with coil embolization and open microsurgery can be a treatment option for multiple PICA aneurysms associated with an AVM.
