A. Hiraide et al., DELAYED RUPTURE OF THE SPLEEN CAUSED BY AN INTRASPLENIC PSEUDOANEURYSM FOLLOWING BLUNT TRAUMA - CASE-REPORT, The journal of trauma, injury, infection, and critical care, 36(5), 1994, pp. 743-744
The delayed rupture of the spleen in a 12-year-old boy is reported. He
was admitted with an isolated blunt splenic injury. Successive echogr
ams revealed an enlarging hypoechogenic region in the spleen. A magnet
ic resonance imaging (MRI) scan showed that this hypoechogenic region
was a splenic pseudoaneurysm. On his 7th hospital day the pseudoaneury
sm ruptured. An emergency laparotomy with splenorrhaphy was performed.
His subsequent clinical course was uneventful and the pseudoaneurysm
was replaced by a hematoma that eventually resolved.
