Fig. 1: Computed tomography (CT): A cystic mass with a diameter of 15 mm in the pancreatic tail (arrow).
Fig. 2: Magnetic Resonance Imaging (MRI): A. Cystic lesion measuring 18 × 14 mm cystic lesion assessed by low signal intensity on T1-weighted image(arrow). B. The same lesion with high signal intensity on T2-weighted image (arrow).
Fig. 3: Endoscopic imaging: A. Endoscopic ultrasonography (EUS) showed a cyst with calcification in the margin (arrow). B. Endoscopic retrograde cholangiopancreatogtaphic image showing a normal main pancreatic duct with no communication with the cystic lesion.
Fig. 4: Histopathology: A. The cystic wall is lined by mature keratinized squamous epithelium and underlying lymphoid tissue. B. The epithelial lining is surrounded by splenic pulp and pancreatic tissue.
