Abstract:
Objective To investigate the CT and MRI findings of thymic carcinoid.Methods The clinical data of 12 thymic car-cinoid patients were analyzed retrospectively.All patients underwent immunohistochemistry and histopathological typing.All CT and MRI imaging features,including morphology,density,signal,presence/absence of capsule,calcification,degree of enhancements,were further analyzed.Results Irregular contour was identified in 8 cases;heterogeneous internal density or signal in 10 cases;absence of capsule in 9 cases;intratumoral calcification in 8 cases;cystic or necrotic component in 7 cases;intratumoral hemorrhage in 2 cases;pericar-dial or pleural effusion in 6 cases;preoperative metastasis in 2 cases;invasion of surrounding structures(vessels)in 10 cases.On con-trast-enhanced images,there were 2 cases with mild enhancement,6 cases with moderate enhancement,and 4 cases with obvious enhance-ment.And tumor enclosing the mediastinal great vessels was observed in 7 cases,among which 4 cases showed tumor thrombi in the superior vena cava,and intratumoral neovascularization was found in 4 cases.Conclusion Thymic carcinoid patients tend to present certain CT and MRI imaging features,mostly manifesting mild to moderate enhancement,infiltrative growth pattern along the medi-astinal vascular space,and concurrent intratumoral vascular sign,which are of vital significance to clinical diagnosis.
