Facts: Scrotal Pyocele
- Also known as scrotal abscess
- Can be superficial (from infected hair follicles, wound) or intrascrotal
- Causes: epididymitis, TB, instrumentation, neurogenic bladder, chronic catheter indwelling, spread from intraabdominal infection (i.e., appendicitis)
- Intrascrotal abscess requires surgical drainage
- US is the modality of choice
- Complex-appearing fluid around the testicle
- Scrotal skin thickening with hyperemia
- Evidence of causes such as epididymitis or others
- Based on imaging, it is difficult to distinguish pyocele from hematocele
