Megacystis-Microcolon–Intestinal Hypoperistalsis Syndrome: A Case Report

A 1-day-old girl, late preterm (36 weeks 3 days) infant, was admitted to the neonatal intensive care unit for respiratory distress and megacystis seen on a prenatal ultrasound at 24 weeks of gestation. A babygram (anteroposterior view of the entire body) showed absence of bowel gas, and abdominal ultrasound revealed grade 4 bilateral hydronephrosis. The patient was subsequently diagnosed with megacystis-microcolon–intestinal hypoperistalsis syndrome and was taken to the operating room for appropriate treatment.

Atrioventricular Discordance with Pulmonary Atresia, Double-outlet Right Ventricle, and Isolated Levocardia: A Case Report of a Rare Congenital Heart Disease

Almost all cases of isolated levocardia or situs inversus with levocardia are associated with congenital heart disease. We report a case of situs inversus with levocardia, double-outlet right ventricle, atrioventricular discordance, pulmonary atresia, patent ductus arteriosus, atrial septal defect, and ventricular septal defect in a neonate. An overview of anatomy and relevant definitions with radiographic correlation will be presented along with a synopsis of current medical literature.

 

A Rare Aneurysmal Bone Cyst of the Rib in an Infant: A Case Report

An aneurysmal bone cyst (ABC) is a rare benign expansile lesion of the bone that consists of hemorrhagic cystic spaces separated by fibrous connective tissue containing osteoid and multinucleated giant cells. The lesion may be primary or secondary. We present a case of ABC in a 7-month-old girl who had a growing, antibiotic-refractory mass in the left chest wall. A computed tomography of the chest confirmed the anatomic location of the mass, but a percutaneous image-guided biopsy and video-assisted thoracoscopic surgery performed during work-up were nondiagnostic. The patient ultimately had a partial rib resection via left thoracotomy. On histologic examination, the mass was found to be an ABC. To our knowledge, this is the second case reported on aneurysmal bone cyst of the rib in an infant. The presented case confirms that ABCs can affect any bone and suggests that the inclusion of an expansile osteolytic lesion of the ribs in differential diagnosis is necessary to facilitate timely treatment that warrants excellent results.
