| 目的 观察儿童单中心型卡斯尔曼病(UCD)CT表现。方法 回顾性纳入7例经术后病理确诊的单发UCD患儿,观察病灶CT表现。结果 7例病灶均呈类圆形,边缘光滑、规整、清晰,最大径15.1~74.3 mm、平均(42.57±19.05)mm;位于颈部、纵隔及腹腔各2例,腹股沟区1例。7例病灶CT平扫均表现为软组织密度灶,其中6例密度均匀且未见明显出血、钙化及坏死,1例位于纵隔者可见短线状高密度钙化灶;6例周围可见卫星灶;增强扫描动脉期可见4例中度强化、3例明显强化,静脉期均呈明显强化。7例病灶周围均可见丰富小血管,3例见裂隙征。结论 儿童UCD CT表现为边界清晰、密度均匀的软组织肿块,增强后明显强化,周围伴丰富滋养血管及卫星灶,部分可见钙化及裂隙征。 |

| Objective To observe CT manifestations of unicentric Castleman disease (UCD) in children. Methods Totally 7 children with solitary UCD confirmed by postoperative pathology were retrospectively enrolled, and CT manifestations of lesions were observed. Results The lesions presented as circular mass, with smooth, regular and clear edge in all 7 cases, the maximum diameter of lesions was 15.1—74.3 mm, and the average diameter was (42.57±19.05) mm. Among 7 cases, lesions located in the neck, mediastinum and abdominal cavity each in 2 cases, respectively, while in 1 case located in inguinal area. Non-enhanced CT showed soft tissue density lesion in all 7 cases including 6 with uniform density without bleeding, calcification or necrosis, while lesion in mediastinum had short linear high-density calcification in 1 case. Satellite lesions around the mass were noticed in 6 cases. After enhanced scanning, in arterial phase lesions moderately enhanced in 4 cases and significantly enhanced in 3 cases, which all significantly enhanced in venous phase, and abundant small blood vessels around lesions were observed in all 7 cases, while fissure signs were observed in 3 cases. Conclusion UCD in children presented as soft tissue mass with clear boundary, uniform density and significant enhancement on CT, with abundant nourishing blood vessels and satellite lesions around, while some with calcifications and fissure signs. |
