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.
Abstract
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.
