Intracranial internal carotid artery aneurysm with metastatic carcinoma

Abstract

Unruptured intracranial aneurysm can be picked up incidentally on cranial angiography screening for other cause. However, with increasing use of neuroimaging led to increasing rate of pickup and many such incidentally detected cases are treated with endovascular treatment, or craniotomy and clipping of aneurysm or uncommonly a very small aneurysm unsuitable for retreatment by currently available modality may be observed as wait and watch policy. Extremely uncommonly a patient undergoing investigation for suspected subarachnoid hemorrhage following aneurismal rupture, computed tomography scan revealed presence of subarachnoid hemorrhage associated with sellar mass. Such association was previously unreported. In extensive Pubmed search by authors could find a case reported by Yang et al., a case of known surgically resected gastric carcinoma developing secondary in sella, CT angiography of the intracranial artery revealed an aneurysm of ICA located at the inner edge of the siphon segment.
