L-Asparginase is a frequently used drug in hematological malignancies. Various side effects associated with its use include hypersensitivity, hyperglycemia, hypercoaguability and acute pancreatitis. We describe a rare complication of pancreatic pseudocyst in a 12 year old boy of Acute lymphoblastic leukemia (ALL) treated with MCP-841 protocol (during re-induction phase). Nearing the end of induction i.e. day 25, patient complained of a painful swelling in the epigastrium and left hypochondrium. Investigations revealed a pancreatic pseudocyst for which he underwent cystojejunostomy. Post surgical period was uneventful.
