“…Prenatal sonographic diagnosis has usually been reported in the second half of pregnancy (Romero et al, 1988;Hertzberg, 1994). There are only very few cases in which the diagnosis was made in the first or early second trimester (Tsukerman et al, 1993;Estroff et al, 1994;Petrikovsky, 1994).…”

“…Although early sonographic diagnosis of intestinal obstruction has been reported as early as 15 weeks' gestation, it usually appears after 27 weeks of gestation [7]. The differential diagnosis in such cases is broad, and includes mid-and hindgut atresia, imperforated anus, meconium ileus due to cystic fibrosis, intestinal malrotation, volvulus and peritoneal bands [8].…”

Nonobstructive Dilatation of the Fetal Bowel in Twin Gestations

Objective: To assess the possible association of in-utero bowel dilatation and circulatory changes with fetal compromise. Methods: A retrospective survey of all ultrasound examinations was performed at the Chaim Sheba Medical Center (n ∼10,000) between 1995 and 1999. Cases with ultrasonographic evidence of bowel dilatation, but without evidence of obstruction, were recruited. In utero Doppler studies of umbilical, splenic, superior mesenteric arteries, and middle cerebral artery (MCA) were performed: systolic/diastolic ratio (S/D), pulsatility index (PI) and resistance index (RI) were calculated in the above arteries and compared with those of normal fetuses. Nonstress test and cord blood pH were also assessed. Neonatal medical records were procured. Results: Four fetuses, all of who were products of twin gestations, showed bowel dilatation without evidence for obstruction. Three of the four fetuses were small-for-gestation-age (SGA) and of bichorionic gestation, while one was of monochorionic twin gestation, with twin transfusion syndrome. In all three SGA fetuses, Doppler studies revealed increased peripheral resistance in the umbilical artery and adaptive peripheral vasodilatation in the fetal midcerebral, splenic and superior mesenteric arteries. In all cases, an abnormal nonstress test led to prompt delivery. Conclusions: Acute fetal bowel dilatation in a twin gestation is associated with abnormal splanchnic and gut perfusion that may lead to fetal compromise.

“…After exclusive use of radiography for diagnostics in the past, in particular for the detection of calcifications (that are not always found),9 , 10 today, ultrasound is considered the “gold standard” 11 , 12. Whether MRI scans can supply substantial additional information is still unclear 13.…”

Case Reports

A testicular tumour-like lesion or a solid extratesticular mass are serious postnatal problems with a broad spectrum of inflammatory or tumorous causes and possible differential diagnoses. In this case report, an extraordinary case of a newborn boy with a rare cause of a periorchitis is described.A premature boy infant (25-year-old mother with obesity) was diagnosed as having a disturbance of prosperity. A plain film of the abdomen showed a dilated intestine (no pathological findings in abdominal ultrasound, in particular, no ascites). After 3 postnatal months of clinical observation at the hospital including temporary parenteral nutrition, hydrocele at both sides was diagnosed. Therefore, the boy underwent surgical exploration. Intraoperatively, the processus vaginalis peritonei was surprisingly filled with meconium; because of that, the situs was extensively rinsed. In addition, the boy underwent an operation for the right and left hydrocele. The testes were preserved (on follow-up investigation there were no further problems).Pathohistological investigation confirmed meconium periorchitis, which is a rare postnatal disease and which can only develop in cases of former meconium peritonitis and if the processus vaginalis peritonei is open. The precise details of cause and pathophysiology in this case may significantly help in avoiding unnecessary orchiectomy.
