Fig. 3. Distal rectal cancer with left levator ani muscle involvement.

Fig. 3

A. On baseline MRI, ulceroinfiltrative mass is observed in distal rectum with tumor infiltration into left levator ani muscle (arrow). B. On post-CRT MRI, signal drop is seen within entire tumor. However, shrunken tumor still invades levator muscle (arrow). Traditional APE was performed. Histopathology revealed tumors with pathologic tumor regression grade 3 and positive pCRM (not shown). C. Follow-up CT 6 months after operation shows recurrent mass at remnant left levator muscle (arrows). CRT = chemoradiotherapy, MRI = magnetic resonance imaging
