case_images: Color Doppler image with linear transducer. the Doppler gate is placed over a blood vessel and shows peaked, high amplitude flow, indicating increased resistance. Hashes are placed at points indicating peak systolic velocity and end diastolic velocity.

case_images: Color Doppler demonstrated scant but central flow with an intratesticular resistive index of 0.75 (normal range 0.48-0.75 in children) (Figure 2).

case_images: POCUS demonstrated heterogenous echotexture with surrounding hydrocele and scant arterial flow, demonstrating a tardus parvus pattern (Figure 3, Video S3).

case_images: During examination, spontaneous increase in blood flow was seen (Figure 4, Video S4,S5), as was a kinked spermatic cord (Video S6).

case_images: Color Doppler image with linear transducer. The testis is on the left of the color window and the circular cord complex ("whirlpool sign') is on the right. The cord complex can be difficult to distinguish from epididymis. Here, there is very little flow in the cord complex, as can be seen in torsion. In contrast, epididymitis would present with epididymal swelling and increased blood flow.

case_images: POCUS showed a testis in the inguinal canal adjacent to the cord complex (Figure 5).
