中文摘要:
      目的 观察儿童软组织卡波西型血管内皮瘤(KHE)CT及MRI表现。方法 回顾性分析11例术后病理证实的KHE患儿,其中7例仅接受CT、3例仅接受MR、1例接受CT和MR检查;10 例病变起源于皮肤伴毗邻软组织受侵,1例起源于咽部软组织、未累及皮肤;9例为单发、2例为多发,共13个病灶,位于四肢6个、躯干4个、头颈部3个,其中5个为局灶型、8个为弥漫型;观察病灶CT及MRI表现。结果 CT显示8例(8/8,100%)KHE均浸润至皮下脂肪及深筋膜,其中3例(3/8,37.50%)累及骨骼;7例(7/8,87.50%)病灶呈等密度、1例呈等-低密度(1/8,12.50%),CT值(30.25±14.32)HU,未见明显静脉石及钙化;增强后病灶均显著强化,CT值(124.30±82.96)HU,其中4例病灶周围见较多血管(4/8,50.00%)。MRI显示4例中3例(3/4,75.00%)侵犯邻近肌肉、1例(1/4,25.00%)累及骨骼;病灶T2WI均呈不均匀高信号、弥散加权成像(DWI)呈高信号,表观弥散系数(ADC)无明显减低,增强后均呈持续性显著强化;其中3例可见流空血管影。结论 儿童软组织KHE的CT及MRI表现、尤其增强CT/MRI及DWI表现较具特征性。
英文摘要:
      Objective To observe CT and MRI manifestations of soft tissue Kaposiform hemangioendothelioma (KHE) in children. Methods Data of 11 children with KHE confirmed by postoperative pathology were retrospectively analyzed, including 7 case underwent CT scanning, 3 case underwent MR scanning and 1 case underwent both CT and MR scanning. The tumors originated from the skin with adjacent soft tissue invasion in 10 cases, while from pharyngeal soft tissue without skin involvement in 1 case. Nine cases were found with single and 2 cases were found with multiple lesions, with a total of 13 lesions, including 6 in the limbs, 4 in the trunk and 3 in the head and neck, 5 were focal type and 8 were diffuse type. CT and MRI manifestations of KHE were observed. Results Involvements of subcutaneous fat and deep fascia were noticed in all 8 cases (8/8, 100%) who underwent CT scanning, while bone involvements were found in 3 cases (3/8, 37.50%). The tumors present as equal density in 7 cases (7/8,87.50%) and equal-low density in 1 case (1/8, 12.50%), with CT value of (30.25±14.32) HU, and no obvious venous stones or calcification was observed. Significant enhancement was observed in all 8 cases (8/8,100%) after administration of contrast agents, with CT value of (124.30±82.96) HU, and blood vessels around the lesions were noticed in 4 cases (4/8, 50.00%). Among 4 cases who underwent MR examination, tumors invaded adjacent muscles in 3 cases (3/4, 75/00%) and affected bones in 1 case (1/4, 25.00%), presenting as uneven high signal on T2WI, high signal on diffusion weighted imaging (DWI) without significant decreased of apparent diffusion coefficient (ADC), with sustained significant enhancement in all 4 cases and empty blood vessel shadows in 3 cases. Conclusion CT and MRI manifestations of soft tissue KHE in children were characteristic, especially on contrast-enhanced scanning and DWI.
