A 1-day-old, full-term male infant had a right groinswelling that was nonreducible. Ultrasonography ofthe right groin demonstrated the presence of calcifi-cations (A, arrowhead), an undescended testicle (A &B, white arrow), and evidence of an incarceratedloopof bowel (B, arrowhead). An abdominal x-ray showedmultiple calcifications in the right groin and scrotalsac consistent with a suspected scrotal meconiumpseudocyst (C, arrowhead).He had diagnostic laparoscopy to evaluate the possi-bility of an intraperitoneal perforation or meconiumperitonitis. It revealed a prenatal incarcerated right in-guinal hernia with a right undescended testicle with noevidence of perforation.

Intraoperative ultrasonography showedadequatebloodflowtothetesticledespiteincarceration.The indirect hernia sac was ligated and a Bassini repairwas used because of the large size and chronic nature ofthe incarcerated hernia, which resulted in disruption ofthe inguinal floor. Careful examination of the intraab-dominal viscera showed no evidence of intestinal perfo-ration. The patient had an uneventful postoperativecourse.Meconium pseudocysts are commonly associatedwith meconium peritonitis, a serious and potentiallyfatal neonatal condition that occurs secondary to fetalbowel perforation.
