Mucinous cystadenoma
Gastric impressions by a mucinous pancreatic cystadenoma Gastric impressions by a mucinous pancreatic cystadenoma
Gastric impression from outside the stomach. The gastric lumen is substantially narrowed. Peristaltic movements are not blocked by this space occupying lesion, rendering an impres- sion from outside very likely. Biopsy foreceps can not flatten the lesion (figure: top right). Ultrasound shows a normal pancreatic head and body (right figure). The pancreatic tail harbours a cystic structure with calcifications peripherally and also centrally. Needle aspiration corroborates the suspected mucinous cystadenoma. Central rather than peripheral calcifications of the cyst are strong hints to this cystic space occupying lesion of the pancreas.
