A meningioma was incidentally identified with computerized tomography (CT) in 17 patients without relevant clinical signs. The tumor was not removed, but biopsy confirming a meningioma was obtained from one patient. Tumor growth rate was calculated from repeat CT scans or follow-up magnetic resonance imaging. The annual growth rate ranged from less than 1% to 21%. It is concluded that in nonsymptomatic meningiomas with a low growth rate a nonsurgical approach may be warranted.
17例无相关临床症状的患者通过计算机断层扫描（CT）偶然发现患有脑膜瘤。肿瘤未被切除，但从1例患者身上获取了活检组织，证实为脑膜瘤。通过重复CT扫描或后续磁共振成像计算肿瘤生长率。年生长率范围从小于1%到21%。得出的结论是，对于生长率低的无症状脑膜瘤，可能有必要采取非手术方法。
