Walsh & Hoyt: Clinical Manifestations, Treatment, and Prognosis According to Site

Dolichoectasia of the intracranial portions ofthe ICAs and their branches may be asymptomatic, or it may cause a variety ofsymptoms and signs that are related to the location and extent of the condition. Thus, dolichoectasia of the petrous portion ofthe ICA may produce lower cranial neuropathies, whereas dolichoectasia of the intracavernous portion of the artery can enlarge the sella turcica and simulate a pituitary tumor, causing diplopia that is often painful. Other authors have recognized abducens palsies related to fusiform aneurysms. Epistaxis has been reported as a rare complication of a dolichoectatic aneurysm involving the cavernous sinus.
