Fibrous pseudotumor of the scrotum
Updates to Article Attributes
Body
was changed:
Fibrous pseudotumour of the scrotum is a relatively rare non-neoplastic extra testicular non-epididymal lesion.
Epidemiology
It affects any age. Although rare, it is considered the third most common extra testicular mass after a scrotal lipoma and an epididymal adenomatoid tumour.
Pathology
It is characterised by usually nodular, probably reactive proliferation of fibrous tissue and inflammatory cells. It occurs due to prior inflammation, infection, or trauma.
Location
It most often involves the tunica vaginalis.
Radiographic features
Ultrasound
Sonographic appearances can be widely variable. They are typically seen as one or more solid paratesticular or tunica nodules or masses with variable echogenicity.
MRI scrotum
- T1: uniformly low signal intensity: due to the presence of fibrosis 4
- T2: uniformly low signal intensity: due to the presence of fibrosis 4
- T1 (C+) Gd: generally show slow but persistent enhancement, as is typical of fibrous tissue, although enhancement can be variable 4
Differential diagnosis
Clinically, it can mimic testicular malignancy.
