A primigravid woman in her 20s who had been pregnant for 16 weeks presented with significant abdominal pain. A noncontrast computed tomographic (CT) scan revealed a 15 × 13 × 11-cm heterogeneous cystic mass that appeared to originate from the body of the pancreas and protrude into the gastric wall (Figure 1, A). Results of CT scan also revealed a 3-cm hypodense lesion on the left lobe of the liver, ascites, and splenomegaly. Further evaluation with endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography revealed extrinsic compression of the gastric wall from a large mixed solid/cystic lesion with septations and well-defined margins with no clear involvement of the gastric wall. A thin, reddish-brown fluid (700 mL) was aspirated from the cystic component. Analysis of the aspirate showed no tumor cells or mucinous material, and normal carcinoembryonic antigen, CA19-9, and amylase. Fine-needle aspiration was performed on the solid component of the cystic tumor (Figure 1, B-E).
