Figure 11a. Postoperative hematocele. (a) Transverse US image obtained 2 months after surgical repair of a large right inguinal hernia demonstrates complex layering of fluid (arrow) in the right scrotal sac, a finding consistent with a hematocele. (b) Sagittal US image obtained after a right inguinal hernia repair in another patient shows a septate fluid collection with fine echoes (arrows) anterior to the testis (area between the cursors). At Doppler imaging in both patients, flow in the testis was normal.
