胸内巨大淋巴结增生的X线CT表现12例分析

Castleman disease of the thorax: X-ray and CT features with 12 cases

目的 :分析胸内巨大淋巴结增生的影像学特征 ,提高术前诊断水平。方法 :回顾性分析 12例病理证实的胸内巨大淋巴结增生X线和CT表现。结果 :胸片检出 12病例共 13个病灶 ,其中边缘清楚圆形、椭圆形肿物 12个 ,分叶肿物 1个。CT增强 4例中见明显均匀强化 ,1例强化不均匀。结论 :巨大淋巴结增大的影像学特点为肿块边缘清楚 ,CT增强扫描可见明显强化 ,对该病诊断有较大价值。

Objective: To characterize the radiologic manifestations of thoracic Castleman disease. Methods: The clinical and histopathologic records; chest radiographs; and computed tomographic (CT) in 12 pathologically proved cases of thoracic Castleman disease were reviewed. Results: Patients with Castleman disease (n=12) typically had solitary (n=12), round or oval-shape (n=12), well-circumscribed (n=12) masses. Unusual manifestations of Castleman disease were multicentric (n=1), and lobulated-shape (n=1). All lesions (n=5) CT demonstrated homogeneous (n=4) or inhomogeneous (n=1) masses with marked contrast enhancement. Conclusion: thoracic Castleman disease manifests as a well-circumscribed mass, CT scan showed strong enhancement. This appearacnce should always raise the possibility of Castleman disease.
