Sonographic diagnosis of a splenic artery pseudoaneurysm incorporated within an infected pancreatic pseudocyst.

In pancreatitis the involvement of adjacent vessels resulting in pseudoaneurysm formation is well known, though quite rare (Gadacz 1978, Kadell & Riley 1967). The diagnosis is usually established on angiography or surgery. We report here a case where the diagnosis of a splenic artery pseudoaneurysm incorporated within an infected pseudocyst, was made sonographically.
