  Fig. 1. (A) Abdominal CT scan shows a non-enhancing septated cystic mass at pancreas tail. (B) T1-weighted image on MRCP shows a septated cystic mass with slightly high signal intensity of the larger chamber. (C) T2-weighted image of MRCP shows a septated cystic mass with slightly low signal intensity of the larger chamber. (D) Endoscopic ultrasound shows a heterogeneously isoechoic cystic mass with daughter cystic lesion. (E) A submucosal cyst lined with stratified squamous epithelium is seen and in some areas, the lining epithelium is attenuated or denuded with erosion (H&E stain, ×15). (F) There is an aggregation of lymphocytes forming a subepithelial rim of lymphoid tissue (H&E stain, ×200).

  Fig. 2. (A) Abdominal CT shows a peripherally enhancing cystic mass at pancreas tail. (B) T1-weighted image of MRCP shows a well-defined cystic mass with focal area of high signal intensity in anterior wall of the mass. (C) T2-weighted image of MRCP shows a cystic mass with high signal intensity with focal wall thickening. (D) Endoscopic ultrasound shows floating debris within the cystic mass along with focal wall thickening. (E) About 2.0 cm sized cyst is seen within the pancreas (H&E stain, ×15). (F) The lining epithelium of the cyst is squamous epithelium and there are abundant lymphocytes accompanied by germinal center formation in the cyst wall (H&E stain, ×200).
