Periprostatic fatty tissue. A 62-year-old patient who had underwent left photodynamic therapy 1 year earlier, and right treatment 7 days earlier. Axial T1-weighted (a), axial T1 FS unenhanced (b) and contrast-enhanced (c) images show a nodular lesion (arrowhead) located in the right rectoprostatic angle, with a high intensity T1 FS signal, unenhanced, corresponding to focal haemorrhagic necrosis of periprostatic fatty tissue
