Intraaxial epidermoid cyst: Report of a rare case and review of literature

Intra-axial epidermoid cysts are rare intracranial space occupying lesions, accounting for ∼1% of all intracranial tumours and are commonly located in the cisternal spaces, mainly in the cerebellopontine angle and parasellar cisterns. A purely intra-axial position as reported in this paper is quite exceptional.The authors report a case of intra-axial epidermoid cyst located in the frontal lobe that was surgically treated. The case is reported in this paper to highlight the fact that, although rare, the possibility of an intra-axial mass being an epidermoid cyst does exist. The origin, clinical course, radiological features, pathological findings, and surgical treatment are discussed based on a review of the literature.
