Figure 11: About 2 years after chemoradiation for cervical cancer, surveillance CT found hydrometra and MR was made for better characterization. Sagittal T2WI (a) depicts a high cervical recurrence causing obstruction of the cervix, with hydrometra. Axial T2WI (b and c) reveal recurrent tumor in the cervix with obstructing the internal os and hydrometra. The tumor doesn’t invade the parametria but the left parametrium is strongly hypointense (arrow in b) and there is left ureteral dilatation (dashed arrow in c). These findings, as also the rectum and sigmoidal parietal thickening, were assigned to inflammatory effects of radiation.
