"Abdominal wall injuries comprise a set of injuries of the abdominal wall and include different forms of muscle injuries, traumatic hernias and injuries to the subcutaneous tissue. They are often overshadowed by the attention to associated “more severe” abdominal visceral injuries."
"Traumatic abdominal wall hernias usually occur at various weak spots of the abdominal wall most frequent are lumbar hernias affecting the inferior lumbar triangle. Spigelian hernias can also occur in a traumatic event and rarely there are trans-diaphragmatic intercostal hernias."

"The main symptom will be abdominal pain and history will often reveal the mechanism of injury frequently a blunt and less often a penetrating abdominal trauma. The physical examination might reveal skin discolouration or ecchymosis in case of blunt trauma or a laceration, stab or gunshot wound in case of penetrating trauma. Other findings include a soft tissue mass or bulge. Typical seat belt injuries should raise the concern for traumatic abdominal wall hernias 2."
"Abdominal wall injuries can be depicted and assessed with ultrasound, CT and MRI and their appearance will vary with the type of injury. Acute injuries will be probably most frequently evaluated in CT in an emergency after blunt abdominal injury."
"Stab wounds and wounds from projectiles might show fluid, air and dirt along the wound track or trajectory."
"Nowadays CT will be often the first-line modality for the workup of penetrating but also non-penetrating abdominal wall injuries also due to its capability of fast and comprehensive imaging of associated vascular, visceral and osseous injuries 1. Besides, CT is highly sensitive in the detection of traumatic abdominal hernias."
"Most muscle contusions, haematoma or muscle strains can be managed conservatively with rest and pain control. In some larger haematomas, patients might need a blood transfusion because of blood loss. A smaller percentage of rectus sheath haematomas with active bleeding might require surgery or endovascular treatment. In acute groin injuries affecting the rectus abdominis insertion surgery will probably be considered 1."
