Figure 1
Figure 1  Endoscopic findings of large polypoidal mass in the descending colon.
Figure 2
Figure 2 Contrast-enhanced abdominal computed tomography. Computed tomography shows the lead point (white arrow) of the intussusception in the descending colon due to an approximately 3-cm cystic mass. A: Axial view; B: Coronal view.
Figure 3
Figure 3 Gross pathological specimen after the left hemicolectomy. A 7.5 cm-sized leiomyosarcoma originating from the descending colon was identified.
Figure 4
Figure 4 Abdominopelvic computed tomography and liver dynamic magnetic resonance imaging. A: Abdominopelvic computed tomography performed 11 mo after left hemicolectomy reveals a new low-density mass, with possible liver metastasis in segments 4 and 8. There is no evidence of local tumor recurrence at the anastomotic site; B: Liver dynamic magnetic resonance imaging reveals a 2.3-cm solid mass with peripheral enhancement and diffusion restriction in segments 4 and 8 of the liver.

Figure 5 Intraoperative finding, gross finding, and pathological specimen. A: Intraoperative finding. After demarcating the tumor location and resection margin using intraoperative ultrasonography, liver segmentectomy of segment 8 was performed; B and C: Gross finding of the resected liver (B) and pathological specimen (C). The resected specimen exhibits a 2.4 cm × 2.2 cm × 2.0 cm white-yellowish solitary mass that is firm and relatively well-demarcated.
