Abstract
Craniopharyngiomas are benign tumors of the sellar and parasellar region for which
surgical resection remains the treatment of choice. There are many publications on
the most frequent postoperative complications, but few reports on subclinical lesions
affecting the arteries of the circle of Willis, despite their high morbidity and mortality
rate. Trauma-induced aneurysms are infrequent, representing less than 1% of intracranial
aneurysms. Iatrogenic intracranial pseudoaneurysms are a subtype of surgically induced
aneurysms developed as a result of direct injury to the arterial wall or after dissection
of tumors adherent to the vessel adventitia. The natural history of these lesions
is not well known because their incidence is extremely low. We report two cases of
postoperative aneurysms of the internal carotid artery after craniopharyngioma resection
and a brief review on the management of such lesions.
