[The sonographic diagnosis of a spontaneous rectus sheath hematoma]

In 4 patients between 52 and 66 years of age with acute abdominal pain, rectus sheath haematoma in the right and left lower quadrant was diagnosed. In one case it was a condition after exertion, in another case after coughing, in the third case in thrombocytopenia and in the last case as a consequence of a contusion. Sonomorphology revealed a spindle-shaped or round hypoechoic mass localised in the rectus sheath. Two of the patients were operated on, and two were treated conservatively.
