(a) and (b) : A long axis scan of the left spermatic cord and testis and the representative line drawing a 5 years old child, four hours after the onset of symptoms demonstrating the characteristic gray scale sonography signs of intravaginal torsion testis. Note the abrupt reduction in the size of the cord with thinning at the point of spiral twist. (Small arrows). The cord proximal to this point is thickened producing the “figure of eight” or “wringing of the cord” or the “twisted cord” sign. The testis appears heterogeneous with an area of increased echogenicity between 5-6’O clock position compatible with focal intratesticular hemorrhage. The reactive hydrocele extends distally high up the cord indicating atypical insertion of the tunica vaginalis pointing to the “bell – clapper” pattern of anomalous testicular suspension
