Epidermoid cyst: highlights on diagnosis and magnetic resonance imaging features

PURPOSE: Epidermoid and dermoid cysts are extremely rare developmental cysts of a benign nature, which may occur anywhere in the body, although about 7% are found in the head and neck. This article reports a clinical case of a patient who had an epidermoid cyst and its magnetic resonance imaging (MRI) features. CASE REPORT: This case discusses an epidermoid cyst in a 36-year-old woman complaining about speech difficulty. Clinical examination revealed an extensive swelling on the floor of the mouth. MRI findings showed a cystic homogenous lesion located underneath the mylohyoid muscle which was removed by surgery. Histological examination of the mass confirmed the diagnosis of an epidermoid cyst. CONCLUSION: We concluded that MRI was considered useful for a more accurate diagnosis prior to treatment.
