Occipital intradiploic epidermoid cyst

Abstract

Intradiploic epidermoid cysts are rare intracranial tumours, with an estimated prevalence of less than 1% of all cranial tumours. Most of the intradiploic cysts are asymptomatic; however, clinical findings consist of headache and tenderness. We presented a case of a 21-year-old female who consulted the neurosurgery department for a period of three years about a mass in the occipital region, which was growing gradually. The patient was treated with surgical removal without complications. Intradiploic epidermoid cysts are infrequent intracranial tumours that primarily affect adults. This tumour has a wide spectrum of symptoms. Radiologic findings on computed tomography (CT) and magnetic resonance imaging (MR) are the cornerstone for the diagnosis, which is finally confirmed by histopathological studies. Surgical management with a complete resection of the cyst and capsule is the most commonly used treatment.
