Intra-axial CNS dermoid cyst.
Intracranial dermoid cysts are rare tumors. They constitute 0.3% of intracranial tumors. These are commonly seen in the midline and sylvian area. Intraaxial lesions are extremely rare. We report the case of a 35-years-old female with a large intraaxial dermoid cyst, which was reported as oligodendroglioma on imaging studies done preoperatively, but was confirmed to be a dermoid cyst intra-operatively and on histopathological examination; thus highlighting a diagnostic dilemma. Patient did well post operatively and there is no recurrence in the one year follow-up. To conclude, dermoid cysts are rare benign tumors, and intraaxial lesions are still rarer. Complete surgical excision may become difficult due to adherence to nerves and vessels.
