Abstract: Objective To study a characteristic CT sign of pulmonary tuberculosis granuloma and improve the diagnostic accuracy of the disease.Methods The clinical data and CT findings of 32 cases with pulmonary tuberculosis granuloma were retrospectively analyzed.All cases were pathologic confimed by bronchoscopy or biopsy.All the patients had spiral CT scan,of which five had CT enhancement.Results In 51 cases of pulmonary tuberculosis granuloma 32 hadCrawling Sign,which showed the trend that le-sions from the peripheral spread to the hilum of lung along the bronchovascular bundle with the outer part larger than the inside,like a lesion crawled along the bronchial tree.Conclusion TheCrawling Signis a quite characteristic CT sign of the tuberculous granu-loma which can help to differentiate tuberculous granuloma from lung cancer and other lung diseases.
