Presentation
Left abdominal pain with palpable mass.
Patient Data
Well-encapsulated ovoid solid cystic mass arising from the corporeo-caudal region of the pancreas, measuring 95 x 85 x 70 mm. The cystic component is of intermediate to high signal on T1, low signal on T2. The solid component is mainly of peripheral location of low signal on T1, high signal on T2 with heterogeneous enhancement on post-contrast sequences.No abdominal lymphadenopathy or intraperitoneal effusion.
Case Discussion
The patient's age and the MRI features are suggestive of solid pseudopapillary tumors of the pancreas (Frantz tumor). In this case, the main differential diagnosis is GIST from the posterior gastric wall.
At surgery, the tumor was originating from the pancreas and the histopathological exam confirmed the diagnosis of solid pseudopapillary tumor (or Frantz tumor).
