Diagnostic imaging of solid pseudopapillary tumor of the pancreas in children: report of two cases

Solid-pseudopapillary tumor of the pancreas (SPT) is an exceptionally rare neoplasm in children. lt is of low malignant potential and occurs most frequently in young females. Patients and methods: A cumulative review of the tumor's radiological characteristics from the English language scientific literature is presented. The clinical course, radiological investigations and outcome of surgery of two children treated at Vilnius University Hospital Santariskiu Klinikos Children 's hospital are analyzed. Results: Total number of 33 SPT was reported in litera/ure in 2000- 2011.4 articles about radiological features of SPT in children were found in reviewed literature. Between 2011 and 2012, two children with SPT were diagnosed at our institution. Both patients underwent abdominal ultrasound and computed tomography (CT) examinations. Preoperative biopsy was performed for both patients. After surgery SPTwas confirmed for both patients. Conclusions: SPT is a rare differential diagnosis of a pancreatic mass in children. SPT might be one of the radiological differential diagnoses in children with big pancreatic tumor within intratumoral hemorrhage, calcifications and pseudocapsule. CT examination is used to evaluate tumor invasion and resectability. Magnetic resonance tomography could be used to avoid radiation exposure
