作者在一亚群神经母细胞瘤中,发现了一种特殊的超声表现,并认为这种特殊的表现可能是神经母细胞瘤的特异性表现。这种特殊的超声表现是由一种占据部分肿瘤肿块的圆形或卵圆形的均匀回声增强的小叶所组成。所有的小叶均呈圆形或卵圆形,边缘光滑。易与周围肿瘤组织分开,无1例不规则或成角。所有有超声小叶的4例患者均为神经母细胞瘤,其中2例在CT扫描上不能识别这种小叶。2例行肿瘤全切术,2例经活检证实。活检证实的1例不久尸解证实有明显的小叶形成,尽管有广泛的出血坏死,显微镜下仍显示小叶形成的特征。
The authors found a special sonographic appearance in a subset of neuroblastomas and believe that this particular manifestation may be a specific manifestation of neuroblastoma. This special ultrasound manifestation consists of a round or oval shaped uniform echo-enhancing leaflet that occupies part of the tumor mass. All leaflets are round or oval, with smooth edges. Easy to separate from the surrounding tumor tissue, no one case of irregular or angled. All 4 patients with ultrasound lobules were neuroblastomas, 2 of which were not able to recognize this lobe on a CT scan. Two patients underwent total tumor resection and 2 patients were confirmed by biopsy. One of the biopsy-confirmed short-lived autopsy confirmed that there was a clear leaflet formation. Despite the extensive hemorrhagic necrosis, the features of leaflet formation were still shown under the microscope.
