Summary:[ABSTRACT]: [Background]: Ruptured epidermoid cysts can cause aseptic meningitis, but spontaneous rupture is very rare. We report a case of spontaneous rupture of an intracranial epidermal cyst. [Case presentation]: A 44-year-old man developed occipitalgia and neck pain seven months ago. A brain tumor was detected on computed tomography, but was only followed up. After his headaches worsened, he visited our hospital. The tumor was located in the parasellar region with multiple small lesions in the sylvian fissure. We diagnosed it as a spontaneous ruptured epidermoid cyst and performed tumor resection. The patient did not develop fever or headache after surgery, and the postoperative course was uneventful. Nineteen months after surgery, the tumor has not relapsed. [Conclusion]: We treated a case of spontaneous rupture of an intracranial epidermal cyst. Since the risk of recurrence increases when the capsule remains, aggressive removal is suggested.
