透明血管型Castleman 病的CT及MRI表现

目的:探讨透明血管型Castleman 病的CT 及MRI 影像表现，旨在提高对该病的诊断水平。方法:回顾性分析4例经手术病理证实的透明血管型Castleman 病的CT 及MRI 资料，总结其特征。结果:左锁骨上窝1 例，纵隔1例，肠系膜1 例，肝胃间隙1例，4例临床类型均为局限型，4例病理分型均为透明血管型。 CT表现为椭圆形软组织肿块，平扫与肌肉相比呈等密度，动态增强4例肿块动脉期明显强化，静脉期及延时期均表现为持续强化。MRI 检查T1WI 病灶呈等信号，T2WI 呈高信号，增强表现与CT 近似。结论: 透明血管型Castleman 病有一定的CT和MRI影像学特征，具有较高的诊断价值，但需病理性确诊。

CT and MRI findings of hyaline-vascular Castleman' s disease

Objective:To study the CT and MRI findings of hyaline-vascular Castleman's disease and improve the diagnostic level to this disease.Methods:The CT and MRI imaging materials of 4 patients with hyaline-vascular Castleman's disease were analyzed retrospectively，diagnosis of hyaline-vascular Castleman's disease was done by surgery and pathology.Results:In these cases，1 case was at left supraclavicular fossa，mediastinum，mesentery，hepatogastric gap.The clinical types were topical type in 4 cases，the pathological types were 4 cases of hyaline-vascular.On CT the lesions were oval softtissue mass.CT scan showed isodense compared with muscle，dynamic contrast-enhanced CT scan of hyaline-vascular type in 4 cases，there was marked enhancement in tumor arterial phase，venous phase and delayed phase appeared as continuing to strengthen.There was thickening shadow of tortuous vascular around the lesions or/and in the lesions in 2 cases.MRI scaning lesion showed the same or slightly lower signal intensity in T1WI and high signal intensity in T2WI，the enhance performance was similar to CT.Conclusion:the CT and MRI have important value in diagnosis of hyaline-vascular Castleman's disease，diagnosis depends on the histopathology.
