Magnetic resonance imaging (MRI) was requested immediately, showing a voluminous prostatic tumor process measuring 429mL, locoregional extension towards the seminal vesicles, the mesorectum, the rectum, the levator ani muscles, the rectus muscle, and the pubic bone, with several bilateral internal iliac nodes and some bone lesions in the left iliopubic bone and coccyx (Figure 1, Figure 2).
