case_images: MRI study demonstrating a locally aggressive prostatic tumor. MRI: magnetic resonance imaging. Axial T2-weighted imaging (T2-WI) (A), gadolinium-enhanced fat-suppressed T1-weighted imaging (FS T1-WI) (B), diffusion-weighted imaging (DWI) (C), and apparent diffusion coefficient (ADC) map (D) reveal a large, locally aggressive prostatic tumor with invasion of the seminal vesicles, lymphovascular bundles, and rectal walls (arrowheads). The lesion demonstrates intermediate signal intensity on T2-WI, hypervascularity on gadolinium-enhanced FS T1-WI, and marked diffusion restriction, as evidenced by high signal intensity on DWI and corresponding low signal intensity on the ADC map

case_images: The lesion demonstrated intermediate signal intensity on T2-weighted images (T2-WI), hypervascularity on gadolinium-enhanced fat-saturated T1-weighted images (FS T1-WI), and marked diffusion restriction, as evidenced by high signal intensity on diffusion-weighted imaging (DWI) and corresponding low signal intensity on the apparent diffusion coefficient (ADC) map (Figure 1).
case_images: MRI study demonstrating multiple metastatic penile lesions.. MRI: magnetic resonance imaging. Sagittal T2-weighted imaging (T2-WI) (A-B) and gadolinium-enhanced fat-suppressed T1-weighted imaging (FS T1-WI) (C-D) reveal multiple lesions involving the corpora cavernosa (arrows; A, C) and the bulbospongiosum region of the penis (arrowheads; B, D). These lesions exhibit intermediate signal intensity on T2-WI and heterogeneous enhancement on gadolinium-enhanced FS T1-WI

case_images: The lesions exhibited intermediate signal intensity on T2-WI and marked diffusion restriction, with high signal intensity on DWI and corresponding low signal intensity on the ADC map, and heterogeneous enhancement on contrast-enhanced imaging (Figures 2-3).
case_images: MRI study demonstrating multiple metastatic penile lesions. MRI: magnetic resonance imaging. Axial T2-weighted imaging (T2-WI) (A), gadolinium-enhanced fat-suppressed T1-weighted imaging (FS T1-WI) (B), diffusion-weighted imaging (DWI) (C), and apparent diffusion coefficient (ADC) map (D) reveal multiple lesions involving the corpora cavernosa and corpus spongiosum with disruption of the tunica albuginea (arrows) and the bulb of the penis (arrowheads). The lesions exhibit intermediate signal intensity on T2-WI, heterogeneous enhancement on gadolinium-enhanced FS T1-WI, and marked diffusion restriction, as indicated by high signal intensity on DWI and corresponding low signal intensity on the ADC map.

case_images: CT showing multiple metastatic lesions in the liver and lungs. Iodine contrast-enhanced computed tomography (CT) reveals multiple metastatic lesions in the liver, characterized as hypovascular nodules with slight peripheral enhancement (arrows, A), and in the lung, presenting as scattered solid nodules (arrow, B)
