 | Media file 1: Polypoid carcinoma of the upper rectum. |
 | Media file 2: Annular carcinoma in the upper rectum. |
 | Media file 3: CT scan of wall thickening in a rectal carcinoma. |
 | Media file 4: CT scan for low rectal carcinoma preoperative staging. Note circumferential thickening of the rectal wall. |
 | Media file 5: CT scan following intravenous contrast medium, revealing hypodense lesions in the right lobe of the liver from metastases of a rectal adenocarcinoma. |
 | Media file 6: CT scan demonstrating presacral recurrence of a tumor following abdominoperineal resection for carcinoma of the rectum. |
 | Media file 7: CT scan following abdominoperineal resection. The presacral mass is a result of fibrosis. Distinction from recurrent tumor may be difficult on imaging alone. |
 | Media file 8: CT scan demonstrating metastases in the right lobe of the liver from a rectal adenocarcinoma. The left kidney is hydronephrotic because of obstruction of the distal left ureter by perirectal spread of the tumor. |
 | Media file 9: Axial MRI scan of a T3a rectal carcinoma, revealing mural thickening from the tumor and extension of the tumor into the perirectal fat. |
 | Media file 10: Hyperechoic hepatic metastases from rectal adenocarcinoma. |
 | Media file 11: Ultrasound of liver revealing hypoechoic metastasis from a rectal carcinoma. |
 | Media file 12: Transrectal ultrasound demonstrating the 5 concentric layers of the normal rectal wall. The mucosa (innermost ring), the submucosa (middle ring), and the serosa (outermost ring) are echogenic (white rings). They are separated by 2 hypoechoic (black) rings, the muscularis mucosa (adjacent to the mucosa) and the muscularis propria (adjacent to the serosa); the rings are best seen in the 5-o'clock position in the full-size view. |
 | Media file 13: Large tumor in left lateral rectal wall with invasion of perirectal fat. A large node is present at the 12-o'clock position. |
