Strong internal diffusion restriction.
Separate smaller subcutaneous cyst in the right glueteal region.
Case Discussion
An example of a perineal abscess - perhaps overkill to have required an MRI, but nevertheless it demonstrates the pathology nicely.
Likewise the appearances on DWI/ADC in abscess are well shown with avid internal diffusion restriction.
The abscess spontaeneously burst whilst awaiting incision and drainage.
