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.

Hydrocoele and periorchitis after extravasation of parenteral nutrition solution

“…Subsequently, the processus vaginalis seems to have obliterated, presumably due to inflammatory oedema resulting from infection and hyperosmolarity of the solution. This phenomenon shows similarity with periorchitis occurring after fetal meconium peritonitis, with (sterile) inflammation in the scrotal sac followed by oedema, adhesions and calcifications 1–3. Grey-scale ultrasonography in combination with colour Doppler imaging is a well-accepted technique for assessing scrotal lesions and testicular perfusions 4.…”

Meconium-induced periorchitis

“…In this report, an extraordinary case of a newborn with a rare cause of a periorchitis and its appropriate treatment are described; knowledge about this specific postnatal disease can have a great impact on avoiding unnecessary orchiectomy 1 , 2…”
