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]

The sign is uncommon.[2] It is named after British physician John Henry Bryant, who first described it in 1903.[3]

Definition

Blue scrotum sign of Bryant is a medical sign associated with a ruptured abdominal aortic aneurysm (AAA) that is leaking relatively slowly.[1]

Signs and symptoms

Abdominal Aortic Aneurysm Location

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

Inguinal canal

Rupture of the aneurysm causes blood to accumulate in the retroperitoneal space and extravasate into the scrotal tissue via the inguinal canal and spermatic cord.[1]

Epidemiology

The sign is uncommon.[2]

History

The sign was first described in 1903 by John Henry Bryant (1867-1906) in autopsies conducted on people who died from ruptured AAA.[3][4]
