Insights

Solid pseudopapillary tumours (SPTs) in children are typically larger than in adults, but share similar clinical and imaging features. Diagnosis should be considered in children with large pancreatic masses, particularly adolescent girls.

Area of Science:

  • Oncology
  • Pediatric Oncology
  • Radiology

Background:

  • Solid pseudopapapillary tumors (SPTs) are rare pancreatic neoplasms, predominantly affecting young women.
  • Distinguishing pediatric SPTs from adult SPTs is crucial for appropriate diagnosis and management.

Purpose of the Study:

  • To compare the computed tomography (CT) imaging features and clinical characteristics of pediatric SPTs with those in adults.
  • To identify any age-related differences in the presentation of pancreatic SPTs.

Main Methods:

  • Retrospective review of CT images and clinical data from 86 patients with histopathologically confirmed SPTs.
  • Patients were categorized into pediatric (≤18 years) and adult (>18 years) groups.
  • Statistical analysis included chi-squared and Student's t tests.

Main Results:

  • Eighteen pediatric patients (15 female, 3 male) with a mean age of 15.1 years were identified.
  • Abdominal pain was the most common symptom in children (66.7%).
  • Pediatric SPTs were significantly larger than adult SPTs (mean 9.1 cm vs. 5.7 cm; p=0.001), with no other significant differences in clinical or imaging features.

Conclusions:

  • This study represents the largest single-center analysis of pediatric pancreatic SPTs.
  • The findings suggest that SPT should be considered in the differential diagnosis of large pancreatic masses in children, especially adolescent females.
  • Similarities in clinical and imaging features, apart from size, highlight the importance of considering SPT across age groups.

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
