Ruptured aneurysm of the middle meningeal artery associated with occlusion of the posterior cerebral artery. Case report

J Neurosurg. 1996 Feb;84(2):269-71. doi: 10.3171/jns.1996.84.2.0269.


The authors describe the case of a 69-year-old man with an intracerebral hemorrhage due to rupture of a nontraumatic aneurysm of the middle meningeal artery (MMA). The ipsilateral posterior cerebral artery (PCA) was occluded, and dural anastomoses developed as the main collateral pathway between the MMA and the cortical branch of the PCA, on which the aneurysm was located. It is considered that increased hemodynamic stress to the collateral pathway contributed to the formation of the aneurysm.
