摘　　要：目的　探讨肺内球形病灶中多结节聚合CT征象的诊断价值。方法　分析了肺内良、恶性球形病灶 12 4例 ,其中恶性 88例 ,良性 36例。病灶大小为 1～ 6cm。经CT平扫后病灶区域薄层重建 ,10例作了HRCT ,8例作了CT增强扫描。结果　 88例恶性病灶中发现CT多结节聚合征者 2 9例 ,36例良性病灶中有 3例。其CT征象以病灶大小不同表现不同 ,病灶 <2cm者为花瓣形 ,病灶 >2cm者为桑葚形和葫芦形。结论　CT多结节聚合征对周围型小肺癌的早期诊断和肺内良恶性病灶的鉴别诊断有一定价值。Objective To study multi-nodule accumulation sign of CT and it′s diagnostic values of peripherial lesion of lung. Methods 124 cases of benign and malignancy peripherial lesion of lung were analyzed. There were 88 cases of peripheral lung cancer and 36 cases of benign lesion. All lesions were 1～6cm in diameter. CT scan was performed on all cases and additional 2～5mm thin slice scans were made in focus range. Enhanced CT scan was performed in 8 cases and HRCT in 10 cases. Results Multi-nodule accumulation sign was found in 29 cases of malignant lesion and 3 cases in benign lesion. CT signs usually showed petal shape (<2 cm in diameter)or mullerry and calabash shape(>2 cm in diameter).Conclusion Multi-nodule accumulation sign is valuable for the diagnosis of pulmonary malignant tumor.
