Paratesticular lesions have a long list of differential diagnoses:

epididymal cyst (most common epididymal mass)
adenomatoid tumour (most common epididymal tumour)
scrotal tunica cysts
- tunica vaginalis cyst
- tunica albuginea cyst
hydrocele
scrotal haematocele
varicocele
scrotolith (scrotal pearl)
inguinal herniation
polyorchidism (supernumerary testes)
spermatocele
sperm cell granuloma
scrotal lipoma: is the most common extratesticular non epididymal lesion of the scrotum; seen in about 22% of patients who had hernia repair
scrotal leiomyosarcoma
fibrous pseudotumour of the scrotum
papillary cystadenoma (of epididymis): most common epididymal mass on those with von Hippel Lindau disease (vHL)
testicular sarcoidosis
tuberculous epididymo-orchitis/epididymitis
spermatic cord
scrotal haemangioma: is often hypervascular on colour Doppler, unlike other benign paratesticular lesions that usually show little vascularity
