Staging CT pre- and post chemoradiotherapy
Abdomen and pelvis: No focal liver lesion. There is a 7 mm soft tissue attenuation exophytic nodule at the upper pole of the left kidney. Spleen, adrenal glands, pancreas appear normal. No free fluid or lymphadenopathy in the abdomen or pelvis. The uterus contains a number of calcifications within the myometrium. The endometrial thickness measures at least 12 mm. There is uncomplicated sigmoid diverticulosis. Some ill-defined soft tissue thickening is seen in the posterior anal canal, apparently extending to the anal cleft. No destructive bone lesion is identified. Conclusion: 1. No evidence of metastatic disease. No convincing rectal lesion, but a low anal lesion with possible extension into the natal cleft is seen. 2. Incidental subcentimetre exophytic nodule at the left kidney suspicious for a small neoplasm; 3. Endometrial thickening. Recommend pelvic ultrasound if clinically appropriate.
