Teratoma Retroperitoneal With Intra-Canal Expansion about a Case

Abstract

The retroperitoneal teratoma is a rare congenital tumor, accounting for only 1-10% of retro primitive peritoneal tumors in children; its extension endo canal is still much rarer. There is a female; the diagnosis can be done either by prenatal obstetric ultrasound, or more often in the neonatal period. Or it can go unnoticed and is discovered in adulthood. We report a case of a 6-month infant, male, no particular history that has a gradual onset flaccid paraplegia from birth and anesthesia of both lower limbs, spinal MRI and abdominal CT showed a large retroperitoneal fibrosis solido heterogeneous right lesion containing calcification and fatty component with intraductal extension for a teratoma. Histological examination confirmed the diagnosis. The purpose of this observation is to show you the contribution of CT in the diagnosis of teratoma in its rare localization.
