Periprostatic dermoid cyst a Coronal T1W image shows a large well-circumscribed mass in the pelvis (white arrows) which is mildly T1 hyperintense to muscle, shows mild fat saturation on (b) axial T1 fat saturation sequence. c Axial T2W image shows the lesion is high T2 signal compared to muscle. It causes significant mass effect on the bladder (red arrow) displacing it anteriorly and exerts mass effect on the prostate and seminal vesicles. d Post-contrast T1 shows no significant enhancement. The lesion shows strong diffusion restriction with (e) high DWI and (f) low ADC. No evidence of calcification, fluid–fluid level or suspicious enhancing nodular soft tissue thickening was identified
