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.
颅内皮样囊肿是罕见的肿瘤。它们占颅内肿瘤的0.3%。这些囊肿常见于中线和大脑外侧裂区域。轴内病变极为罕见。我们报告一例35岁女性患有巨大轴内皮样囊肿，术前影像学检查报告为少突胶质细胞瘤，但术中及组织病理学检查证实为皮样囊肿；从而突出了诊断上的困境。患者术后恢复良好，在一年的随访中无复发。总之，皮样囊肿是罕见的良性肿瘤，轴内病变更为罕见。由于与神经和血管粘连，完整的手术切除可能会变得困难。
