Meconium periorchitis

Meconium Periorchitis is Amenable to Prompt Radiological Diagnosis

“…Differential diagnoses of neonatal scrotal swelling are hydrocele, inguinoscrotal hernia, testicular neoplasm, testicular torsion, and organizing hematoma. [ 1 2 3 4 ] Calcifying testicular neoplasms can be teratoma, Sertoli cell tumor, metastatic neuroblastoma, paratesticular rhabdomyosarcoma, and lymphoma. MPO is an extremely rare possibility.…”

“…The presence of abdominal calcifications in addition to scrotal calcifications on radiography, reported in 38.7% of the cases, strongly suggests the possibility of MPO. [ 2 ] Symptomatic meconium peritonitis can be associated in about 20% of cases. [ 1 ] Any accompanying clinical or sonographic findings consistent with meconium ileus, peritonitis, intestinal atresia (such as fetal echogenic bowel and polyhydramnios), dilated bowel loops, ascites, or pseudocyst may aid in diagnosing MPO.…”

“…[ 1 5 ] Rarely, during inguinal herniotomy, calcifications in the hernia sac, along with an amorphous mass adherent to the testis were discovered, which on HPE, MPO was diagnosed. [ 1 2 ] Spillage of fetal meconium into its peritoneal cavity can occur from intrauterine bowel perforation secondary to volvulus, bowel atresia, or mesenteric vascular insufficiency. Meconium in the peritoneal cavity initiates chemical peritonitis.…”

“…A total of 32 cases of MPO are identified from 1986 to 2021. [ 2 ] Fetal USS (fUSS) was employed as the most frequent antenatal diagnostic imaging technique. The most common fUSS findings were fetal hydrocele with hyperechogenic lesions representing peritesticular calcifications or mass, which were found in 58.8% of cases, in which it was employed.…”

“…Fetal magnetic resonance imaging (MRI), used only in 2 cases, detected scrotal mass/fluid-filled scrotum with thick wall and septa. [ 2 ] There has been no instance, in which postnatal MRI scan has been resorted to for diagnosing MPO.…”
