“…First recognized by Neuhauser [20], calcification has been the most reliable radiographic sign of meconium peritonitis and can be detected antenatally [4,10,11,13,24]. Boikan [2] stated that calcium deposition may occur within 24 h of meconium spillage.…”

Meconium peritonitis occasionally occurs as a localized, encysted collection of meconium ranging from a few centimeters in size to huge cysts occupying most of the abdominal cavity. The cyst wall consists of fibrous granulation tissue and the cyst may contain only meconium or may also encase loops of bowel. Gas within the cyst indicates persistent communication between the perforated bowel and the cyst cavity; if the perforation seals over in utero the cyst remains gasless. Calcification is a variable finding. Sonography in two neonates with cystic meconium peritonitis showed well-defined, echogenic masses, one of which contained calcifications and was detected in utero.

“…On sonography their cyst had a central echogenic core with an anechoic halo. Fetal ascites [10,13] and hydrops [18] both have been observed on antenatal sonograms in cases of meconium peritonitis.…”

“…The importance of the assessment of fetal bowel echo genicity, alone or in conjuncture with other sonographic signs, is manifest by the reported association of fetal com plications with increased echogenicity [1][2][3][4][5][6][7][8]. The differ entiation of these complications from normal rests upon several other sonographic findings, rather than upon the degree of bowel echogenicity alone.…”

“…Increased echogen icity in the fetal abdomen, as revealed by ultrasonogra phy, has been associated with several pathologic condi tions such as meconium peritonitis [1][2][3][4][5][6], meconium ileus [7,8], neoplasms and infections. However, several au thors [9][10][11] reported on increased intestinal echogenicity with subsequent normal neonatal outcome.…”

Ten plates of normal fetal ultrasonography (at 16-20 weeks’ gestation) showing fluid, liver, lung, bone and intestine were submitted to electro-optical transmission surface densitometry. A distinct echogenic gradient has been found and used as an ‘internal standard’ to evaluate intestinal echogenicity. Intestine had significantly different echogenic properties from bone, liver and fluid but similar to that of lung. Using this echogenicity scale for fetal bowel, observers were correct in 46%, overscored in 32.6% and underscored in 21.4%. These poor results may be due to the significant inconsistency in the interpretation of each plate compared to other plates (about 65%). Although the densitometry-derived grading scale seems valid at these gestational ages, interobserver variation is too large and precludes a simple ultrasonic diagnosis of the hyperechogenic fetal intestine. Densitometric evaluation may be indicated in suspected cases when fetal bowel seems to have increased echogenicity.

“…Because this form of small-bowel obstruction may present early in life as an emergency, it would be helpful to identify prenatally those newborns at risk for meconium ibeus. Numerous case reports have documented prenatal findings associated with meconium peritonitis, including pobyhydramnios, fetal ascites, peritoneal wall calcifications, and intraabdominal cysts [2][3][4][5][6][7]. To date, however, no one has described the sonographic appearance of uncomplicated meconium ileus in the fetus.…”
