Figure 10b. Central pelvic recurrence of cervical carcinoma in a 46-year-old woman after surgery. (a) Sagittal T2-weighted fast spin-echo MR image (3,500/90) shows an ill-defined inhomogeneous mass (arrows), which has high signal intensity relative to that of back muscle. Loss of low signal intensity in the wall of the urinary bladder is indicative of invasion. (b) Axial contrast-enhanced gradient-echo MR image (120/1.5) shows a central recurrent mass with an irregular, thick, enhancing wall and invasion of the right pelvic side wall (arrow). (c) Axial T2-weighted fast spin-echo MR image (4,000/104) obtained at the renal hilum shows moderate right hydronephrosis.
