RETAINED CONTRAST AFTER EMBOLIZATION OF A RIGHT GASTRIC ARTERY PSEUDOANEURYSM

Pseudoaneurysms due to chronic pancreatitis can be a source of major g astrointestinal (GI) hemorrhage, Computed tomography (CT) is the prima ry diagnostic imaging modality for pancreatic pseudocysts associated w ith GI bleeding. Pseudoaneurysms and associated GI bleeding can be dia gnosed and embolized with transcatheter techniques once the arterial a natomy is defined. CT is a useful modality for follow-up examination o f the pseudocyst; the findings must be correlated with other procedure s performed on these patients. On follow-up studies, contrast medium r etained in the pseudocyst after embolization may falsely signal persis tent bleeding into the pseudocyst.
