Figure 10a. Older hematocele. Sagittal US images obtained approximately 1 week (a) and 6 weeks (b) after trauma show uniform echotexture and internal flow in both testes, but with differences in the echotexture of the hematoma. A complex cystic mass (arrow in a) anterior to the left testis represents a hematoma with a hematocele. The mass demarcated by cursors in b had a more complex and more masslike appearance that was believed to be due to a clot. At surgery after 6-week follow-up US, a large amount of fluid and an old clot were found with an intact testis. LT T = left testis, RT T = right testis.
