S. Turpin et al., ANOTHER RIM SIGN - A PATENT PROCESSUS-VAGINALIS DEMONSTRATED BY PERITONEAL TC-99M SC SCINTIGRAPHY, Clinical nuclear medicine, 20(8), 1995, pp. 729-730
The ''rim sign'' is usually associated with a missed testicular torsio
n. Here, a ''rim sign'' was demonstrated during peritoneoscintigraphy,
in a case of an indirect inguinal hernia. Activity was found not only
along the inguinal canal, hut also around the testicle due to a large
patent processus vaginalis. An intravenous injection of Tc-99m pertec
hnetate helped evaluate the respective size of the right and left side
s of the scrotum.
