Introduction: Solid-pseudopapillary neoplasms (SPN), or Frantz tumor, is a rare, low-grade neoplasm that occurs mainly in young women. It was described in 1959 by Virginia Frantz and constitutes 0.2-2.7 % of all pancreatic tumors. Computed tomography (CT) plays an important role in the diagnosis of this pathology of scarce reporting. The objective of the present study is to describe the epidemiological and tomographic characteristics of the SPN in the Instituto Nacional de Enfermedades Neoplásicas (INEN) of Peru. Methods: Descriptive cross-sectional study performed with medical records of all patients diagnosed with SPN between 2004 and 2014. The variables described were tumor size, location, shape, borders, thickness of the capsule, composition, calcifications and uptake of contrast. The categorical variables were expressed in absolute and relative frequencies; while the numerical variables were described with median and interquartile deviation (ID). Statistical support STATA Version 12.0 was used. Results: Of all pancreatic cystic tumors (PCT), 51.9% corresponded to confirmed cases of TSP. The median age was 23.5 years. The isolated location in the head predominated (33.3%); the most frequent mixed location was body and tail (16.7%); diameter was more frequent between 5.1-10 cm and the content of the majority was predominantly solid. 30.0% of the NSP presented calcifications. Aim conclusion: Most cases of INP SPN (2004-2014) have similar characteristics to those reported in the international literature.
