Multidetector CT imaging features of solid pseudopapillary tumours of the pancreas in male patients: distinctive imaging features with female patients

Abstract

Objective: To describe multidetector CT imaging features of solid pseudopapillary tumours (SPTs) in male patients and to compare these imaging features with those found in female patients. Methods: The institutional review board approved this retrospective study. We included the CT images of 72 patients (M:F 5 12:60; mean age, 35.0 years) diagnosed with SPT by histology. CT images were reviewed on the following: location of the tumour, maximal diameter, shape, margin and the fraction of the tumour composition. Statistical differences in CT imaging features were analysed.

Características tomográficas del tumor sólido pseudopapilar de páncreas (tumor de Frantz)

“…La ecografía y la tomografía son los exámenes de imágenes que se usan con frecuencia como apoyo diagnóstico 5 . En el presente estudio se hizo uso de la tomografía; esto debido a que las características de interés a reportar (sugeridas por Park MJ, et al 8 ) sólo eran posibles visualizar dicha instrumento de imagen.. Respecto a sus características tomográficas, la ubicación aislada más frecuente fue en la cabeza (33.3 %). Un reporte de TSP en niños refirió a la ubicación en cabeza en el 30.0 % de ellos 13 , y 42.1 % en una serie de 19 casos norteamericanos reportados entre 1990 y 2002 14 .…”

“…Se diseñó una ficha de recolección para registrar los datos de las HC seleccionadas. Esta ficha incluyó una adaptación de las características de imágenes del estudio de Park MJ, et al: localización del tumor, diámetro transverso máximo, forma, márgenes, grosor de la cápsula, calcificaciones según forma y distribución, componente sólido o quístico y patrones de contraste 8 . Posterior a ello se elaboró una base de datos en el programa Microsoft Excel 2010.…”

An Atypical Presentation of Pancreatic Pseudocyst Masquerading as Solid Pseudopapillary Neoplasm of Pancreas

“…SPN accounts for 1% of all pancreatic neoplasms with high female predominance [ 5 ]. Although it is most prevalent in young women of the second decade of life, approximately 17% of cases are males with a higher mean age of presentation [ 6 ]. SPN is composed of poorly cohesive epithelial cells arranged in solid and pseudopapillary structures [ 7 ].…”

“…The ratio of solid to cystic components tends to be higher in males than females, showing that males have a slower rate of degeneration than females [ 8 ]. Calcification in SPN has been observed in 30% of cases [ 6 ]. Several patterns of calcification, including focal nodular, amorphous or scattered, incomplete or complete rim calcifications, have been observed in SPN, though no calcification pattern is significantly associated with malignant transformation [ 9 ].…”

Clinical update on the management of pseudopapillary tumor of pancreas

“…Atypical SPNs on CT have no surrounding capsule, solid or cystic component with hyper attenuation during pancreatic phase and dense internal calcification with no defined margin[ 52 ]. Park et al[ 53 ] studied CT imaging features of SPNs in males and females. The results showed that lobulated shape is more common among males and oval shape in females[ 53 ].…”
