Delayed pancreatic pseudocyst formations. Long-term complication of L-asparaginase treatment

L-asparaginase-induced pancreatitis has been reported during or closely following administration of the drug. Three cases of pseudocyst of the pancreas in two women and one man have previously been reported with the use of intravenous L-asparaginase. An adolescent male developed acute pancreatitis and pseudocyst of the pancreas 16 weeks after cessation of intramuscular L-asparaginase. Delayed pseudocyst of the pancreas can be a complication of intramuscular L-asparaginase.
