CT findings of adrenal schwannoma
چکیده انگلیسی


• Adrenal schwannomas were extremely rare, and eight cases' medical data of this disease were collected in this study.
• They usually presented a well-defined unilateral mass with cystic degeneration and sepations.
• They manifested characteristic progressive contrast enhancement pattern on enhanced CT images.

AimTo analyse the computed tomography (CT) imaging features of patients with adrenal schwannoma.Materials and methodsEight cases of adrenal schwannoma confirmed by histopathology were included in this study. All eight patients had undergone multiphase CT examinations. The features of the adrenal schwannoma in the CT images were analysed retrospectively in detail, including size, shape, margin, radiodensity, calcification, and enhancement pattern.ResultsThere were six male and two female patients, with a median age of 44.5 years (range, 25–52 years). Two patients complained of right flank pain, and two with left upper abdominal discomfort, while the remaining patients were diagnosed by routine ultrasound examinations. On unenhanced CT images, all cases of adrenal schwannoma were well circumscribed, rounded or oval, heterogeneous masses with cystic components, with two cases exhibiting calcification, and three cases with septa. On enhanced CT images, all cases displayed mild heterogeneous enhancement of the tumour during the arterial phase, and progressive enhancement during the portal venous phase and equilibrium phase.ConclusionAdrenal schwannoma commonly presents as a well-defined unilateral mass with cystic degeneration, septa, and a characteristic progressive contrast-enhancement pattern on multiphase enhanced scans.
