Cystic lesions deriving from the omentum are rare benign clinical conditions of uncertain etiopathogenesis. In this report we describe a case of antenatal diagnosed intra-abdominal cystic mass, which, due to the absence of symptomatology and constant ultrasound morphology over time, did not require immediate treatment. The present patient was followed up until surgery, which was performed at 4 years of age: on laparoscopy a cyst within the greater omentum was identified and excised. Histopathology indicated a cyst with epidermoid structure, which is unusual among the omental cysts reported in the literature.

Thoraco-abdominal trauma can in rare cases involve diaphragmatic rupture and subsequent herniation of intra-abdominal contents. We report a case of this complication in a 5-year-old boy who was injured in a car crash, and who manifested respiratory distress and hemodynamic instability after 48 h of being monitored in the pediatric intensive care unit. Multiple radiologic investigations were inconclusive and the definite diagnosis was established only on thoracoscopic exploration.
