The blue scrotum sign of Bryant, also known as Bryant's blue sign, is bruising of the scrotum, typically associated with a ruptured abdominal aortic aneurysm (AAA).[1] It generally appears three or four days after first experiencing pain, though may occur hours after and sometimes weeks after the rupture.[1]
Definition
editBlue scrotum sign of Bryant is a medical sign associated with ruptured abdominal aortic aneurysm (AAA) that is leaking relatively slowly.[1]
Signs and symptoms
edit
Bruising of one side or both sides of the scrotum may be seen three or four days after leakage of the aneurysm.[1]
Cause and mechanism
edit
Rupture of the aneurysm causes blood to accumulate in the retroperitoneal space and extravasate into the scrotal tissue via the inguinal canal.[1]
Epidemiology
editThe sign is uncommon.[2]
History
editThe sign was first described by John Henry Bryant (1867-1906) in autopsies conducted on people who died of AAA.[3][4]
