Testicular torsion if not promptly recognised and managed, can lead to testicular loss. Predominantly occurring in young boys, if not
detected at an earlier stage could lead to severe debility and handicap them in their adult life. Color Doppler US is essential to
confirm or exclude testicular torsion, which is recognized by an absence of detectable blood flow in the testis. Here we present a
case of a 13 year old boy who presented with acute left sided scrotal swelling and pain since 12 hrs.
