【Objective】To study the imaging manifestation of solitary pulmonary tuberculous cavity.【Methods】 Eighty seven patients suffering from solitary pulmonary tuberculous cavity underwent chest X-ray,and 27 of them underwent CT scan.【Results】①The incidence of tuberculous cavity was 35.1%,and 22.5% of them were solitary pulmonary tuberculous cavity.②Solitary tuberculous cavity imaging features: most of the tuberculous cavity(79.3%) were thick walled cavity,and the thickness was uneven(82.6%).27.5% of them were thick walled cavity with inner wall tubercle,and 24.1% with a simple solution plane.The outer edge was empty or rough fuzzy barb with shallow sublobe,but without small and deep sublobe.All cases had satellite lesion and bronchial drainage shadow.In addition,CT showed that two cases had tuberculous cavity wall calcification.【Conclusion】 Most kinds of the pulmonary tuberculous cavity are thick walled cavity.In particular,the image of the cheese thick walled cavity is similar to that of lung cancer cavitas.However,tuberculous cavity has no small and deep sublobe.Satellite lesion,bronchial drainage shadow,disseminated lesion of the neighboring lobes of the lung or bronchi segmentales and tuberculous cavity wall calcification are the characters of tuberculous cavity which are important for differential diagnosis.
