{Abstract}: Transdiaphragmatic intercostal herniation is a rare injury that can be associated with blunt trauma. Since its first documentation within the literature in 1946, there have been less than 50 cases reported. We present a case involving a 56-year old female who presented to our Trauma Center with transdiaphragmatic intercostal herniation caused by blunt trauma from a high-velocity T-bone vehicular collision. Upon presentation, she exhibited bilateral breath sounds; however, with labored breathing, chest pain, and hypoxia. The initial chest radiograph interpretation indicated the presence of "left lower lobe infiltrates", and subsequent computed tomography imaging identified "a small lateral hernia along the left mid abdomen". After initial resuscitation, her condition deteriorated, exhibiting respiratory distress and becoming increasingly hypercarbic, requiring intubation. Review of the imaging showed disruption of the left hemidiaphragm with intrathoracic herniation of colon and stomach through the thoracic wall between the ninth and tenth ribs. Consequently, a thoracotomy was performed in the operating room, revealing a large defect between the two ribs with disruption of the intercostal muscles and inferior displacement of rib space. Lung and omentum had herniated through the disrupted rib space and the diaphragmatic rupture was attenuated anteriorly, measuring 11x6cm. After reduction of the herniated organs, a biologic porcine mesh was placed and an intermediate complex closure of the thoracic wall hernia was performed. The patient was later extubated, recovered from her injuries with no complications and was discharged. With the low incidence of transdiaphragmatic intercostal herniation, there is no standardized surgical management. Recent literature suggests that these injuries should be managed with mesh, rather than sutures only, due to high rates of recurrence. Furthermore, diaphragmatic injuries may suffer a delay in diagnosis. Therefore, a high index of suspicion should be maintained in patients with respiratory distress following a blunt trauma, with close review of computed tomography.
