Incidentaloma: cephaleas revealing partial thrombosis of internal carotid artery aneurysm during a 30-week pregnancy of amenorrhea: a case report

Abstract

Abnormal dilatation of the wall of an intracranial artery under the influence of various factors results in what we call a cerebral aneurysm. This creates a pocket where blood accumulates, as it communicates with the vessel via a collar.1 When an aneurysm has not yet ruptured, it is usually detected incidentally, but sudden onset of headache should prompt a search for an intracranial vascular cause.2 In this work, we report a case of a patient who presented with sudden onset of headache which revealed partial thrombosis of an aneurysm of the internal carotid artery during a pregnancy presumed to be at 30 days' gestation + 5 days in severe preeclampsia.
