A chronic collection of pancreatic fluid (rich in amylase, lipase and enterokinase) surrounded by a nonepithelialized wall of granulation tissue and fibrosis is referred to as a pseudocyst. Though most frequent loacation is the lesser peritoneal sac, 20% are located at extra pancreatic sites like pleura, mediastinum, pelvis, spleen, liver and perinephric space. Rarely, it can be present as a psoas abscess and this type of presentation is common in middle aged men who are chronic alcoholic. Recent history of pancreatitis may be present. CECT whole abdomen is initial investigation of choice. Presence of high level of amylase and lipase in the aspirate from psoas abscess is confirmatory for the diagnosis.

The incidence of a falciform ligament is very rare. Because of the rarity of the condition and sparsity of available literature, it's very difficult to diagnose this condition preoperatively. In this case, a 65-year-old lady had presented with pain in epigastrium and vomitings for 3 days. All blood investigations were normal except serum Alkaline phosphatase (ALP) and serum gamma-glutamyl transferase (GGT) which were 141 IU/L and 275 U/L respectively. USG revealed only chronic cholecystitis. On diagnostic laparoscopy, falciform ligament abscess was detected which was adequately drained. The patient responded well with the drainage without recurrence till date. Laparoscopic cholecystectomy was also done in the same sitting.
