横纹肌肉瘤是儿童软组织中较常见的恶性肿瘤,发生部位以头颈部居多。这种肿瘤的局部浸润相当广泛,可有早期和广泛地转移。因鼻咽、付鼻窦和中耳等器官接近脑膜表面,故称脑膜旁区为宜。本文报告1961至1976年Anelerson医院治疗27例16岁以下的脑膜旁横纹肌肉瘤患者,其中13例原发于鼻咽,9例付鼻窦,5例中耳。鼻咽横纹肌肉瘤患者中有2例初期就侵犯中枢神经,其余患者无脑膜 Rhabdomyosarcoma is a more common malignancy in children’s soft tissues and occurs mostly in the head and neck. The local infiltration of this tumor is quite extensive, with early and widespread metastases. As the nasopharyngeal, sinuses and middle ear and other organs close to the surface of the meninges, so called the meningeal area is appropriate. This article reports the treatment of 27 cases of meningeal rhabdomyosarcoma below the age of 16 in the Anelson Hospital from 1961 to 1976, of which 13 were primary in the nasopharynx, 9 were in the sinuses, and 5 were in the middle ear. Two patients with nasopharyngeal rhabdomyosarcoma invaded the central nervous system at the initial stage, and the remaining patients had no meninges
