title: Meconium periorchitis: case report and literature review.
abstract: Meconium periorchitis (MPO) is an uncommon entity associated with healed meconium peritonitis. The typical presentation is soft hydrocele at birth which becomes harder in weeks as the meconium calcifies. It mimics a scrotal mass, and, without knowledge of this rare disease, this may lead to unnecessary surgery. Both the masses and the calcifications have the tendency to resolve spontaneously without compromising the testicle. Sonographic features together with an abdominal plain film are diagnostic, and visualization of the normal testicle may be helpful in differentiating this tumor-like lesion from scrotal tumors. A case of a meconium periorchitis is reported on and the radiological and histological features are discussed with a literature review on the subject.
