Abdominal ultrasonography and contrast-enhanced abdominal computed tomography (CT) scans showed the presence of a partially septated giant cystic lesion measuring 20 x 11 x 13 cm in the abdominal cavity (fig. 1).
On magnetic resonance cholangiopancreatography, the pancreatic body lesion detected by the CT scan was depicted as high-intensity area on a T2-weighted image.

T2-weighted images. These findings were consistent with the characteristics of cystic lesions (fig. 2).
A distal pancreatectomy with splenectomy was performed. The cystic content was serous fluid of a dark, muddy color, suggesting previous bleeding.

The cystic content was serous fluid of a dark, muddy color, suggesting previous bleeding (fig. 3).
On histopathological examination, the lining membrane had a papillary structure composed of cuboidal cells with round nuclei (a). The cells stained PAS-positive (b) and diastase PAS-negative (c), thus indicating the presence of glycogen. These findings led to the definitive diagnosis of SCN.
