Gray-scale and color Doppler US images of the testicle shows a complex fluid collection (stars) around the testicle and marked scrotal skin thickening. The epididymis is edematous with increased flow (image not shown).
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
Imaging
- 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
