title: A case of epidermoid cyst in an intrapancreatic accessory spleen mimicking pancreas neoplasms: MRI with DWI.
abstract: We report on a rare case of an epidermoid cyst in an intrapancreatic accessory spleen (ECIAS) that presented as a cystic lesion in the tail of the pancreas, in a 21-year-old woman. ECIAS is very rare; thus, accurate diagnosis before surgery is difficult. When a wall within the lesion presents with similar imaging features to accessory splenic tissues on magnetic resonance imaging with diffusion-weighted imaging, ECIAS should be considered in the differential diagnosis of cystic lesions in the tail of the pancreas.
