Figure 16. (a) T₂ weighted sagittal fast-spin-echo scan demonstrating a very large cervical cancer invading the posterior bladder wall (arrow). (b) T₂ weighted sagittal scan demonstrating a very large vesico-vaginal fistula which developed after radiotherapy at the site of the patient's primary cervical cancer. Bullous oedema is also noted affecting the bladder wall (star). Multiple biopsies of the vaginal wall and bladder revealed no recurrent disease.
