Congenital Hemidiaphragmatic Agenesis Presenting as Reversible Mesenteroaxial Gastric Volvulus and Diaphragmatic Hernia: A Case Report

A 70-yr-old woman complained of left sided chest pain and non-bilious vomiting for four days after taking a gastric bloating agent for an upper gastrointestinal study. The chest radiography revealed gastric air-fluid levels and bowel loops in the left thoracic cavity. An emergency thoracotomy was performed. The abdominal organs (stomach, spleen, splenic flexure of the colon) were in the left thorax and the entire left hemidiaphragm was absent. There were no diaphragmatic remnants visible for reconstruction of the left diaphragm. We provided warm saline irrigation and performed a left lower lobe adhesiotomy. Thirteen days after surgery, the chest radiography showed improvement in the herniation but mild haziness remained at the left lower lung field. Here we present the oldest case of congenital diaphragmatic agenesis presenting with transient gastric volvulus and diaphragmatic hernia.
