Desmoid tumors, also called deep or aggressive fibromatosis, are uncommon mesenchymal tumors characterized by proliferation of fibroblasts in an abundant collagen extracellular matrix. They rarely involve the pancreas, and the diagnosis is difficult to make if they do. Only eleven cases have previously been reported involving the pancreas in a review of the literature. In these reported cases, ...

endocrine tumors of the pancreas (islet-cell tumors) are rare with neuroendocrine origin. the patient was a 41- year- old man, admitted with chief complains of epigastric mass feeling, dull abdominal pain, lack of appetite and weight loss up to 2-3 kg since 6 months ago. in physical examination, a mass was detected in epigaster and left upper quadrant (luq). in abdominal x-ray, a calcified mass...

Solid and papillary epithelial neoplasm of the pancreas (SPEN) is an encapsulated, slowly enlarging abdominal mass that generally shows no evidence of capsular invasion, regional lymph node involvement, or distal metastases. We present a 68 years old Hispanic male diagnosed with SPEN 5 years earlier that refused surgical excision. Presently he underwent a whole-body 18F-FDG PET/CT. Although tum...

CONTEXT Cystic tumors of the pancreas have been diagnosed with increasing frequency. Intraductal oncocytic papillary neoplasm is a rare type of cystic pancreatic tumor. Intraductal oncocytic papillary neoplasm is considered a distinct entity with the potential of developing into invasive carcinoma and it should be differentiated from other cystic tumors of the pancreas, including mucinous cysti...

OBJECTIVE To describe the computed tomography (CT) features of neuroendocrine tumors (NETs) and solid pseudopapillary tumors (SPTs) with unilocular cyst-like appearance, and to compare them with those of unilocular cystic tumors of the pancreas. MATERIALS AND METHODS This retrospective study was approved by our Institutional Review Board, and informed consent was waived. We included 112 pancr...

CONTEXT Solid pseudopapillary tumor of the pancreas is a rare tumor more common in young girls and rare in males. CASE REPORT We present a case of a solid pseudopapillary tumor of the pancreas in a 13-year-old boy, with typical imaging features. CONCLUSIONS Our case report specifically illustrates the potential of diffusion-weighted imaging findings on solid pseudopapillary tumor in pediatr...
