【摘要】：目的探讨和分析透明血管型Castleman病的CT表现,提升诊断准确率。方法回顾性分析2010年7月—2015年5月行CT双期增强扫描并经病理证实的透明血管型Castleman病的23例患者资料。结果23例透明血管型Castleman病中,21例增强扫描病灶呈显著均匀强化,均分布在大血管旁,且被迂曲粗大血管包绕;1例病灶呈轻度均匀强化,分布在升结肠旁,周围无大血管;另1例骨盆诸骨有成骨性和溶骨性骨质破坏。23例中有4例含钙化灶,其中1例CT表现为中央区星芒状钙化灶,3例边缘分别呈线状、弧线和点状钙化灶。1例病灶位于左颈部,手术切除后1年原手术区复发。结论透明血管型Castleman病肿瘤位于大血管旁并被粗大迂曲血管包绕者呈显著强化,CT动静脉双期呈持续性显著均匀强化,钙化的特征对透明血管型Castleman病的诊断具有重要价值。成骨性和溶骨性骨质破坏,局限性透明血管型Castleman病手术切除后复发属罕见表现。
[Abstract]:Objective to investigate and analyze the CT features of transparent vascular type Castleman disease and to improve the diagnostic accuracy. Methods from July 2010 to May 2015, 23 patients with transparent vascular Castleman's disease were retrospectively analyzed. Results among 23 cases of transparent vascular type Castleman's disease, 21 cases showed homogeneous enhancement in contrast enhancement, all of them were distributed around the large vessels, and 1 case showed slight homogeneous enhancement, which was distributed beside the ascending colon, and no large vessels were found around the lesions. In the other case, osteogenic and osteolytic bone destruction was found in the pelvic bones. 4 of the 23 cases had calcification foci, of which 1 case showed starlike calcification in the central region and 3 cases showed linear margin. One case was located in the left neck and recurred 1 year after resection. Conclusion the tumor of transparent vascular type Castleman's disease is located next to the large vessel and surrounded by large and tortuous vessels, and the CT arteriovenous dual phase is continuously and uniformly enhanced. Calcification is of great value in the diagnosis of transparent vascular type Castleman's disease. Osteogenic and osteolytic bone destruction and recurrence of local transparent vascular Castleman's disease are rare.
