pseudocyst
Pronunciation: SOO-do-sist
Fluid collection lacking epithelial lining, commonly occurring after pancreatic surgery or pancreatitis.
Full Definition
A pseudocyst is a fluid-filled cavity that lacks a true epithelial lining, distinguished from true cysts by this absence of epithelial cells. In pancreatic surgery, pseudocysts may develop as complications following pancreatectomy or as sequelae of acute pancreatitis. They contain pancreatic enzymes and debris, and may require drainage if symptomatic or enlarging. Editorial guidance: Always written as one word, not 'pseudo-cyst' or 'pseudo cyst'.
Usage
Usage note: Written as single word without hyphen; specify anatomical location when clinically relevant.
