Blue Scrotum Sign of Bryant (1903)
Scrotal ecchymosis associated with ruptured abdominal aortic aneurysm (AAA). Extravasation of blood in the retroperitoneum may lead to nontraumatic discoloration beneath intact penile or scrotal epithelium. Ecchymosis typically appears within 3 to 6 days after AAA rupture.
In these two articles Bryant correctly describes the diffuse nature of the atheromatous changes, the possible clinical presentation of AAA as apparent renal colic, and the scrotal and abdominal discolourations as diagnostic clues.
In one case blood was effused into the right spermatic cord, and the corresponding half of the scrotum was much ecchymosed…When blood is extravasated into the anterior abdominal wall ecchymoses may appear…‘Bryant JH. Clin Jour. 1903;23:79
1987 – RM Ratzan et al, identified the correct historical attribution of lower abdominal/scrotal discolouration secondary to aortic aneurysmal disease as belonging to John Henry Bryant.
