Posterior circulation aneurysms in a child: clipping of one leads to spontaneous thrombosis of the other.
Multiple intracranial aneurysms in children are infrequent. This case involves an 11-year-old girl who presented with subarachnoid hemorrhage with posterior cerebral and superior cerebellar artery aneurysms. Initially, she underwent clipping of the posterior cerebral artery aneurysm. Four months later, she returned for clipping of the other aneurysm, at which time it was found to have completely thombosed. The literature contains 4 other cases of spontaneous thrombosis of intracranial aneurysms in children, but only one aneurysm < 25 mm in size is described. The clinical, surgical, and radiological features of this case and a detailed literature review are presented.
