Mesenchymal chondrosarcoma of the rectus sheath case report with ultrasonic findings

The ultrasonic findings in a 54 year old white male with a rare tumor, mesenchymal chondrosarcoma, involving the rectus sheath are described. The sonogram confirmed the tumor's location in the anterior abdominal wall and provided useful information regarding its extent. An interesting feature was the lesion's relative sonolucency, apparently due to its myxoid content.
