Clinicopathological Features of Small Pancreatic Neuroendocrine Neoplasms 10 mm or Smaller.

ABSTRACT: Background/Objectives: There is limited evidence on imaging characteristics and pathological grading of small pancreatic neuroendocrine tumors (PNENs). This study aimed to compare imaging features and histopathological diagnoses of PNENs based on tumor size. Methods: Patients with PNEN who underwent pathological diagnosis at Hiroshima University Hospital were retrospectively reviewed. Detection rates, imaging findings, and diagnostic accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) were analyzed according to tumor size. Results: Among 107 patients with PNEN, 42 had tumors ≤10 mm, and 65 had tumors >10 mm. The detection rate for lesions ≤10 mm was 92.3% according to EUS and 83.3% according to contrast-enhanced CT, showing the superior sensitivit
