Figure 7a. Extratesticular hematoma in a patient with scrotal swelling after a right inguinal hernia repair. Transverse US images demonstrate a large hypoechoic region (8.6 x 3.8 x 4.7 cm) within the right-sided scrotal wall on the gray-scale image (a) and no internal flow on the color Doppler image (b), findings that are indicative of an extratesticular hematoma (H). The right testis in b appears to have normal internal flow.
