Diagnosis and endoscopic endonasal management of nontraumatic pseudoaneurysms of the cranial base.

Abstract

BACKGROUND:

Nontraumatic pseudoaneurysms of the cranial base are rare and present unique diagnostic and treatment dilemmas compared with both true aneurysms and pseudoaneurysms outside of the cranial base. There is a dearth of knowledge regarding the management of these complicated lesions.

METHODS:

Nontraumatic pseudoaneurysms of the cranial base internal carotid artery (ICA) were retrospectively identified at the University of Pittsburgh Medical Center through a key word search of cranial base cases from 2010 to 2017.

RESULTS:

Three cases were identified, demonstrating pseudoaneurysms of the cavernous and petrous ICA. Each patient underwent diagnostic work-up with computed tomography, magnetic resonance imaging, and angiography, followed by endovascular occlusion and endoscopic endonasal surgery, which resulted in relief of presenting complaints and ablation of the pseudoaneurysm.

CONCLUSION:

Symptomatic cranial base pseudoaneurysms should undergo treatment to obliterate the aneurysm and relieve the mass effect. First, formal angiography is necessary for accurate diagnosis and treatment planning. Next, endovascular occlusion is performed, with a preference for coiling or endoluminal reconstruction with a flow diverter. Last, endoscopic intervention follows in cases where: (1) decompression of vital structures is indicated; (2) diagnosis of the pseudoaneurysm cannot be definitively confirmed with angiography; or (3) the etiology of the confirmed pseudoaneurysm requires further investigation.
