Contribution of Medical Imaging in the Diagnosis of Epidermoid Cyst of the Anterior Fontanel in an Child: A Case at the “Mother-Child" University Hospital Center (Chu) Bamako Luxembourg

Abstract

This study aims to identify the epidemiological, clinical, radiological, surgical and histological characteristics of epidermoid cysts. The epidermoid cyst of the anterior fontanel is a very rare congenital lesion, less frequent than the dermoid cyst. We report a case of a four-month-old infant who consulted for a mass located at the level of the anterior fontanel. This lesion presented at birth as a small, soft mass covered with normal-looking scalp that gradually enlarged. Computed tomography showed the characteristics of a slightly heterogeneous cystic lesion limited by the superior sagittal sinus below, without intracranial extension. The surgical intervention allowed its ablation in one piece without adhesion. Histology confirmed the diagnosis. The evolution was satisfactory.
