【摘要】：目的旋前方肌肿瘤早期不易发现,本文探讨旋前方肌血管瘤高频超声表现与病理对照分析,以提高旋前方肌血管瘤的超声诊断水平。资料与方法回顾性分析经手术及病理证实的23例旋前方肌血管瘤患者的超声像图特点,观察病灶大小、边界、内部回声、钙化,实时动态观察肿块与周围组织的毗邻关系以及血供情况。结果 23例病灶均位于旋前方肌内,最大者约50 mm×50 mm×40 mm,最小者约10 mm×10 mm×9 mm,其中11例旋前方肌血管瘤内可见静脉石、钙化灶声像。实质回声型8例:超声示形态不规则的低强不均质回声,部分可见囊实混合性回声,多见钙化,边界清楚,包膜完整,与周围组织界限清晰;CDFI以连续性静脉血流频谱为主;病理类型为海绵状血管瘤、混合型血管瘤。囊性回声型12例:声像为相互交错的管状暗区低无回声光团,呈蜂窝状,少有钙化,边界清楚,无明显包膜,与周围组织界限尚可分辨;CDFI见暗淡血流信号;病理分型为蔓状血管瘤、混合型血管瘤。混合回声型3例:超声示中低强不均匀回声,夹杂有点、带状或不规则偏强回声区交错分布声像,多见钙化,边界不清,无明显包膜,与周围组织界限分辨不清,与周围肌肉肌腱神经关系密切;CDFI见少许血流信号,偶见搏动性低速高阻型动脉血流频谱;病理分型为混合型血管瘤。超声与病理诊断的符合率为87%(20/23)。结论高频超声可以清晰地显示旋前方肌血管瘤,可作为旋前方肌血管瘤首选无创的检查方法,通过分型有助于提高术前诊断率。
[Abstract]:Objective it is difficult to find the tumor in the early stage of pronator muscle tumor. In order to improve the diagnostic level of pronator anterior muscle hemangioma, the high frequency ultrasonic findings and pathological analysis were discussed. Materials and methods the ultrasonographic features of 23 patients with anterior circumflex hemangioma confirmed by surgery and pathology were retrospectively analyzed. The size, boundary, internal echo and calcification of the lesions were observed. The relationship between tumor and surrounding tissues and blood supply were observed dynamically. Results all the 23 lesions were located in the anterior circumflex muscle, the largest was about 50 mm 脳 50 mm 脳 40 mm, and the smallest was about 10 mm 脳 10 mm 脳 9 mm. Among them, 11 cases of anterior circumflex hemangioma could be seen with phleboliths and calcified foci. There were 8 cases of parenchymal echo: ultrasound showed irregular low intensity and uneven echo, partial mixed echo with calcification, clear boundary, intact capsule, and clear boundary with surrounding tissue. CDFI was mainly composed of continuous venous blood flow spectrum. The pathological types were cavernous hemangioma and mixed hemangioma. 12 cases of cystic echo type: the acoustic image was a low echoic mass of interlaced tubular dark area, with honeycomb shape, few calcification, clear boundary, no obvious envelope, and the boundary of CDFI could be distinguished from the peripheral tissue. Histopathologic types were vines hemangioma and mixed hemangioma. Mixed echo type in 3 cases: ultrasound showed low and low intensity inhomogeneous echo, mixed with a little, band or irregular strong echo region staggered distribution of sonography, calcification, unclear boundary, no obvious capsule, and could not distinguish from the surrounding tissue boundary. There were a few blood flow signals in CDFI and pulsatile low velocity and high resistance arterial blood flow spectrum in peripheral muscle tendon nerve, and the pathological type was mixed hemangioma. The coincidence rate between ultrasound and pathological diagnosis was 87 / 23. Conclusion High-frequency ultrasound can clearly display the anterior circumflex hemangioma and can be used as the first non-invasive method for the examination of the anterior circumflex hemangioma. The classification is helpful to improve the preoperative diagnosis rate.
