Comparison is made with the previous examination. At the site of the previously identified anal lesion, no clearly viable residual tumour is identified. At the point of previously identified contact with the internal sphincter at the 3 o'clock position, there is a 17.7 x 2.3 x 11.6 mm lesion with no definite high T2 signal identified to suggest active tumour identified. Previously the lesion measured 25.5 x 5.9 x 20 mm. The rectum and anal sphincters appears normal.
Since previous, the endometrial thickness has normalised. 1.5 centimetre posterior loops of uterine leiomyoma is again noted.
Conclusion: Apparent excellent tumour response with significant reduction in size and no definite residual tumour signal (mrTRG 1).
