Coexistence of intracranial epidermoid tumor and multiple cerebral aneurysms

Abstract

Rationale:There were a few case reports concerning epidermoid tumor coexisted with multiple cerebral aneurysms. Here, we present one case of coexistence of intracranial epidermoid tumor and multiple cerebral aneurysms and performed a literature review.Patient concerns:A 42 years old male patient was admitted to our institution with complaints of headache and dizziness.Interventions:The radiological examinations showed a hypointense lesion in the right parasellar and petrous apex region and an ipsilateral saccular aneurysm originated from the M2–M3 junction of the right middle cerebral artery (MCA) and a saccular aneurysm of the clinoid segment of right internal carotid artery (ICA).Interventions:The patients underwent a right frontotemporal approach for removal of the epidermoid tumor and clipping of the MCA aneurysm in one stage. The aneurysm located at the clinoid segment of ICA was invisible and untreated during operation.Outcomes:No postoperative complications were found in the patient. The patient's follow up after 5 years of surgical treatment was uneventful, and the untreated aneurysm remains stable.Lessons:The coexistence of intracranial epidermoid tumor and cerebral aneurysm is a rare event. The secondly inflammation in cerebral arterial wall may be responsible for the aneurysm formation. Surgical treatment of the intracranial epidermoid tumor and cerebral aneurysm repair may be an optimal scheme in one stage.

Intracranial Dermoid in Patients With Fibrous Dysplasia

“…The coexistence of intracranial ECs and other intracranial abnormalities had seldom been reported. A total of 23 cases of coexistence with intracranial EC were reviewed 7,16–36 . Among these patients, the most common location of ECs was CPA (n=9) and parasellar area (n=7), which was in accordance with regular solitary intracranial ECs 37 .…”

Epidermoid Cysts – A Wide Spectrum of Clinical Presentation and Successful Treatment by Surgery: A Retrospective 10-Year Analysis and Literature Review

“…These cysts can develop in any area of the body with about 7% occurring in the head-and-neck region. Extracutaneous development has been observed in the oral cavity and intraosseous, and in various internal organs including the cerebrum [ 2 ][ 3 ][ 4 ]. Secondary infection and inflammation due to wall rupture are possible complications.…”
