Spermatocele is seen as an unilocular extratesticular cyst with low level internal echoes.
Case Discussion
Spermatocele is seen as a unilocular or rarely multilocular extratesticular cyst caused by cystic dilatation of tubules of the efferent ductules in the head of the epididymis.
On ultrasound studies, they appear as well-defined epididymal cystic lesions, with low-level fine internal echoes, usually measuring 1-2 cm with posterior acoustic enhancement. Thin septations may be present
Differential diagnosis
- epididymal cyst
- ectasia of rete testes
- intratesticular simple cyst
- encysted hydrocele
