(a) Preoperative transverse contrast material-enhanced CT scan shows a large exogastric leiomyosarcoma (arrows) with extensive central necrosis. (b) Follow-up transverse contrast-enhanced CT scan obtained 16 months after surgical resection shows two well-defined, discrete soft-tissue peritoneal nodules (thick white arrows) at the previous tumor site, a finding that represents PL. Multiple hepatic metastases (black arrows) and a small amount of ascites (thin white arrows) in the left subphrenic space also are seen.
