This injury results in intense abdominal pain, which can mimic an acute abdomen. The diagnosis is difficult by physical exam since most hematomas are in the posterior rectus sheath and are not palpable or visible. Palpation of the abdominal wall may reveal a tender mass that is accentuated by contraction of the rectus. Ultrasound and CT can confirm the diagnosis.
