E N D
Types • Cysts of the epididymis • Spermatocele
Cysts of the epididymis • Congenital, derived from an embryonic remnant around the epididymis • Filled with crystal clear fluid
Cysts of the epididymis: clinical features • Found during middle life • Usually bilateral • Cysts: • Located behind the body of the testis • Tense (aggregation of a number of small cysts like bunch of tiny grapes) • Fluctuation difficult appreciate • Transillumination: Chinese lantern pattern
Cysts of the epididymis: D/D • Cysts of the appendages of the testis
Cysts of the epididymis: T/t • If small no T/t is needed • Surgical if the cyst is large & causing discomfort • Aspiration is useless, as these cysts are usually multilocular
Spermatocele • Acquired • Unilocular • Retention cyst • Cysts contain fluid resembling barley – water containing spermatozoa
Spermatocele: clinical features • Scrotal swelling • Location: head of the epididymis, above & behind the body of testis • Testis can be felt separately from the body of the testis • Soft • Fluctuation: usually positive • Transillumination test: negative
Spermatocele: T/t • Aspiration • Excision of the cyst
