A Rare Case of Meckel-Gruber Syndrome with Congenital Intestinal Atresia and Abdominal Pseudocyst Clinic.

Abstract

Background: Meckel-Gruber syndrome (MGS) is a rare disease with a fatal, autosomal recessive inheritance pattern. This article mentions the neonatal MGS case followed by intestinal atresia and meconium pseudocyst clinic. Case presentation: Bile-containing-fluid was aspirated from the fetus, which was found to have polyhydramnios, gastric dilatation, lung hypoplasia, and cystic formation with a diameter of 68*62mm in the abdomen at 32 weeks of gestation in the intrauterine period. The cyst recurred after 2 weeks. We operated the patient with the preliminary diagnosis of meconium pseudocyst due to intrauterine perforation. The general condition was moderate in the postoperative period, and intermittent bilious vomiting continued. We performed an ileostomy on the patient due to his inability to tolerate oral intake, lack of passage, and abdominal distension. In addition, as a result of liver biopsy, cholestasis, cholestatic changes, bile-duct loss, and ductular reaction were detected. According to the current clinical findings and genetic analysis results, the patient was diagnosed with MGS. Conclusion: Autosomal recessive, fatal diseases such as MGS are pathologies with a high probability of recurrence with each pregnancy. Therefore, awareness needs to be increased to prevent these diseases.
