[Show abstract][Hide abstract] ABSTRACT: We present ultrasound, computed tomography and magnetic resonance imaging findings in a case with pancreatic solid pseudopapillary tumor and their correlations with histopathology. Ultrasound revealed a hypoechogenic mass, and computed tomography revealed a hypodense mass at the pancreatic head minimally enhanced after intravenous contrast agent administration. Magnetic resonance imaging showed a hypointense mass on unenhanced T1-weighted images including a hyperintense focus representing the hemorrhage. The lesion was hyperintense on T2-weighted images. On the postcontrast images the lesion showed peripheral thin contrast enhancement in arterial phase and enhanced slightly diffusely in venous and equilibrium phases. The patient underwent elective resection of the mass and pancreatoduodenectomy with jejunostomy tube placement. A final diagnosis of solid pseudopapillary tumor was made histopathologically. Solid pseudopapillary tumor is a rare pancreatic tumor. It is important to make the diagnosis preoperatively because with an adequate surgical resection the prognosis is good. A multimodalitary approach, especially magnetic resonance imaging can suggest the diagnosis without the need for biopsy.

[Show abstract][Hide abstract] ABSTRACT: We describe five patients diagnosed with von Hippel-Lindau disease who complained of abdominal distension, pain and discomfort for a long time. All patients underwent ultrasonography, CT scan and MRI, which showed huge pancreas filled with multiple cysts. Additionally, extrapancreatic findings such as cerebellar hemangioblastoma (3 patients), retinal hemangioblastoma (2), renal cell carcinoma (3), renal adenoma (1), renal cysts (4), and splenic cyst (1) helped to reach the right diagnosis. One patient who had no known associated pathology had a family history of von Hippel-Lindau disease. Pancreatic cysts detected on imaging may be a clue to the diagnosis of von Hippel-Lindau disease. In all patients with multiple pancreatic cysts, this disease should be included in the differential diagnosis.
