The association of arteriovenous malformation and aneurysm within the posterior cranial fossa--report of a case.
A relatively rare case of cerebellar arteriovenous malformation (AVM) associated with a saccular aneurysm fed by the left posterior inferior cerebellar artery (PICA) is described. The interpretation of angiograms and the appropriate surgical treatment for the coexistence of the intracranial AVM and aneurysm are discussed. It is a fact that the steal phenomenon existed in the flow of contrast medium during the angiography. The appropriate surgical treatment may be clipping of the aneurysmal neck first and then radical excision of the AVM.
