Traumatic abdominal wall hernia (TAWH) following blunt injury is a rare clinical entity, induced by traumatic disruption of the abdominal wall's muscle and fascia, alongside abdominal organ herniation. A thorough clinical examination and a high level of suspicion are necessary for the diagnosis. We present the case of a 45-year-old individual who presented to the surgical outpatient clinic with a left lateral bulge in his belly caused by a mountaineering accident. After obtaining a thorough history of the mechanism of injury and clinical assessment, abdominal ultrasonography and computed tomography (CT) scan revealed a significant traumatic left lateral abdominal wall hernia. The patient subsequently underwent an open surgical mesh repair, followed by anatomical and functional restoration of the muscular deficit over the mesh, with an uneventful postoperative course. TAWH constitutes a diagnostic challenge, and in many cases remains untreated for long periods of time. Considering that TAWH occurs in less than 1% of all blunt abdominal trauma, many surgeons are unaware of this rare manifestation. Here we suggest that elective surgery with an open, tension-free polypropylene mesh repair appears to be an appropriate therapeutic option.
