Hemorrhage into pancreatic pseudocyst.
We report a patient whose upper abdominal pain was due to an alcoholic pancreatic pseudocyst with hemorrhage. CT showed a gradually enhancing pancreatic pseudocyst about 6 cm in diameter. It exhibited hyposignal intensity on T2-weighted images and hypersignal intensity on T1-weighted images. Enlargement of the pancreatic pseudocyst was thought to be attributable to hemorrhage into the pancreatic pseudocyst. Angiography revealed a pseudoaneurysm in the anterior superior pancreaticoduodenal (ASPD) artery. Selective transcatheter arterial embolization (TAE) of the ASPD artery stopped the bleeding and his abdominal pain lessened. After 1 month, the diameter of the pseudocyst was reduced to about 3 cm and it showed hypersignal intensity on T2-weighted images and hyposignal intensity on T1-weighted images. TAE was considered to be a minimally invasive, highly effective treatment in this patient with hemorrhage into a pancreatic pseudocyst.
