PDFAbstract
Objective To analyse the magnetic resonance (MR) imaging features of adrenal schwannoma. Methods Two cases of adrenal schwannoma confirmed by histopathology were included in this study. Both patients had undergone MR examinations. The features of the adrenal schwannoma in the MR images were analysed retrospectively, including size, shape, margin, intensity and enhancement pattern. Results There were two female patients, with a age of 56 and 52 years, respectively. Both patients were diagnosed incidently, without any symptom. On unenhanced MR images, both cases of adrenal schwannoma were well circumscribed, rounded or oval, heterogeneous masses with cystic components in one case and septa in the other one. On enhanced MR images, both cases displayed mild heterogeneous enhancement of the tumour during the arterial phase, and progressive enhancement during the portal venous phase and equilibrium phase. Conclusion Adrenal schwannoma commonly presents as a well-defined unilateral mass with cystic degeneration, septa, and a characteristic progressive contrast-enhancement pattern on MR multiphase enhanced scans.
