Abstract:
Objective To evaluate the imaging findings of thoracic Castleman's disease (CD)to improve the diagnostic accuracy. Methods The imaging findings of 14 cases of thoracic CD confirmed by pathology were analyzed retrospectively.Plain and dynamic contrast-enhanced CT scans were performed in all patients before surgery.Results Among the 14 cases,10 cases were hyaline vascular type (HVT)and other 4 cases were plasma cell type (PCT).HVT-CD showed well-define,homogeneous soft-tissue lesion with different sizes of lymph nodes around the lesions in 2 cases,mottled calcification in 2 cases and coarse calcification in 1 case.Dynamic enhanced CT showed HVT-CD had obvious enhancement in arterial phase,and sustained enhancement in venous phase and delayed phase.PCT-CD all showed enlarged lymph nodes in the mediastinum and bilateral axillary,associated with interstitial pneumonia,pulmonary nodules,ground glass opacity and pleural effusion,with marked and sustained enhancement 1 case.Conclusion Thoracic HVT-CD presents equal density on CT plain scan,and obvious and durative enhanement on multiphase contrast-enhanced CT,which can be accompanied by lymphnodes around the lesions and intratumoral calcification.With the above imaging findings,we should consider the possibility of HVT-CD.CT features of PCT-CD are non-specific,a comprehensive evaluation of the clinical data should be combined,but the obviously enhanced PCT-CD can be diagnosed.
