EVERY WHITE ON CT IS NOT BLEED: CASE REPORT OF A RARE, ATYPICAL WHITE EPIDERMOID TUMOR.

Abstract

Epidermoid tumors are benign congenital tumors within the neurosurgical domain, with white epidermoids constituting a rarer subset characterized by distinct radiological features. Here, we report the case of a 50-year-old female presenting with recurrent headaches, initially misdiagnosed as an intracranial aneurysm but later revealed to be a sellar-originating white epidermoid tumor. Despite its size, conservative management was chosen due to the lesion's benign nature and lack of symptomatic contribution. White epidermoid tumors pose diagnostic challenges as they share radiological features with other intracranial lesions, including dermoid tumors, neuroenteric cysts, craniopharyngiomas, and clival tumors. Surgical resection carries a risk of chemical meningitis from tumor content leakage. Therefore, accurate preoperative diagnosis is imperative for appropriate management. In conclusion, white epidermoid tumors represent a rare variant requiring meticulous radiological evaluation to ensure accurate diagnosis and optimal patient care.
