Intersphincteric Epidermoid Inclusion Cyst: Report of a Rare Case: Mri and Ultrasonography Findings

A wide range of lesions can be considered in the differential diagnosis of perineal cystic lesions. Still, Epidermoid inclusion cysts of the perineal region are a rare entity, which require appropriate diagnosis and management. Here we describe the unusual case of a large protruding epidermoid inclusion cyst originating from the intersphincteric anal plane, which was mobilized and excised successfully. Essential investigations to ensure accurate diagnosis in addition to surgical techniques to reduce recurrence and patient morbidity are described in this case report. Ultrasonographic and conventional magnetic resonance imaging (MRI) ndings are noted along with the diffusion-weighted MRI ndings. To our knowledge, only a few studies in the literature have focused on the value of MRI and USG ndings in the differential diagnosis of perineal cystic lesions.
