神经母细胞瘤是幼儿期最常见的实质性肿瘤之一。虽然它可起自任何交感神经节,但65～75%发生于肾上腺髓质或其它非肾上腺的腹膜后部位。本文复习了21例神经母细胞瘤患儿的超声图像,特别注意到大小、部位、内部回声、无回声区及边界。所有病例均经肿瘤活检及骨髓中找到瘤细胞确定诊断。 Neuroblastoma is one of the most common solid tumors in childhood. Although it can arise from any sympathetic ganglion, 65 to 75% occurs in the adrenal medulla or other non-adrenal retroperitoneal sites. This article reviews ultrasound images of 21 children with neuroblastoma, with particular attention to size, location, internal echo, echo-free zone, and border. All cases were diagnosed by tumor biopsy and tumor cells found in bone marrow.
