  • Insulinoma: Imaging Features and Correlation with Pathological Findings (Analysis of 8 Cases)

    ObjectiveTo investigate the imaging features of insulinoma on multi-slice spiral CT (MSCT) and magnetic resonance imaging (MRI) with correlation of pathology. MethodsAll images of 8 patients confirmed by surgery and pathology were retrospectively analyzed with correlation of pathology. MSCT scans were performed in 4 patients and MR scans in 6 patients, among which 2 patients accepted both MSCT and MRI examinations. ResultsInsulinoma in all patients manifested as solitary lesions with diameters of 0.5-3.5 cm. Four lesions demonstrated isodensity or hypodensity on plain MSCT, with significant enhancement on arterial phase, and relative isodensity or slight hyperdensity on portal phase and delay phase. On plain MRI, lesions demonstrated hyperintensity on T1WI, slight hyperintensity or hyperintensity on T2WI. The enhanced patterns of insulinoma were similar to the findings on MSCT. ConclusionsThe imaging characteristics of insulinoma reflect the pathological features. MSCT and MRI are effective in the diagnosis of inslinoma, and MRI can show more diagnostic information.
