ABSTRACT: The posterior meningeal artery (PMA) usually
originates from the third segment of the vertebral artery. Many variations in
its origin and course have been observed; however, as far as we know, the association of true aneurysm of the PMA
and its anomalous origin from the internal carotid artery has not been reported
previously. We reported the case of a 59-year-old woman who suddenly presented a loss of
consciousness without head trauma, computed tomography (CT) revelated intracerebellous
hematoma associated with a subarachnoid hemorrhage of the posterior cerebral
fossa. Cerebral angiography demonstrated a true aneurysm of the PMA which
originated from the internal carotid artery.
