A 60-year-old woman with cervical squamous cell carcinoma, treated with brachytherapy, demonstrating complete response to treatment. Initial staging pelvic MRI depicts the fungating cervical mass with left parametrial invasion (open white arrows) on coronal oblique and sagittal T2 TSE (a). Also note the mass is causing malignant hydrometra due to cervical obstruction. Follow-up pelvic MRI for treatment planning depicts optimal positioning of ovoid and tandem intracavitary brachytherapy device on axial and sagittal T2 TSE with intracavitary device at the level of the cervical tumour and probe tip in the endometrial cavity. Foley catheter (f) in situ. Follow-up pelvic MRI performed 1 year after RT demonstrates complete response with reconstitution of the normal zonal anatomy of the cervix and presence of homogeneous low signal intensity of the cervical stroma (white arrows) on axial and sagittal T2 TSE (c), which are reliable indicators of complete response and absence of tumour in the post-irradiation cervix. Low T2 signal has replaced intermediate signal in the left parametrium (white arrow on axial image in c) indicating parametrial fibrosis
