Paratesticular lesions have a long list of differential diagnoses:

neoplastic
- benign
  - epididymal cyst (most common epididymal mass)
  - scrotal tunica cysts
- spermatic cord lipoma
- scrotal haemangioma: is often hypervascular on colour Doppler, unlike other benign paratesticular lesions that usually show little vascularity
- scrotal lipoma (most common paratesticular neoplasm, usually arising from spermatic cord; seen in about 22% of patients who had hernia repair) ¹
  - peritesticular lipoma
- fibrous pseudotumour of the scrotum
- papillary cystadenoma (of epididymis): most common epididymal mass on those with von Hippel Lindau disease (vHL)
- adenomatoid tumour (most common epididymal tumour)
malignant
