Figure 1 Computed tomography imaging and magnetic resonance imagining. A: Computed tomography imaging of the abdomen: Heterogeneous density within the prostate and heterogeneous enhancement after enhancement, suggesting possible prostate cancer, possible pelvic lymph node metastasis, pelvic floor fascia, and rectal wall and seminal vesicle invasion; B-D: Prostate magnetic resonance imagining: Mixed signals in the prostate, with possible prostate tumor invasion of the lower posterior bladder wall, rectal mesentery, and bilateral seminal vesicles, with multiple lymph node metastases in the pelvis.
