Abstract
|
|
|
A 24-year-old female patient presented with a midline extra-axial posterior fossa lesion. We failed to suspect this lesion could be a giant thrombosed aneurysm of PICA (posterior inferior cerebellar artery) preoperatively, and didn¡¯t perform
preoperative angiogram even after rather typical finding of thrombosed giant aneurysm on MRI.
We suggest a giant thrombosed aneurysm should be included in the differantial diagnosis of any round extra-axial mass lesion in the skull base.
