Bronchiectasis and infectious X-ray analysis of 23 cases misdiagnosed as tuberculosis
x-ray findings and pulmonary tuberculosis have much in common, it is easy to process in the diagnosis of misdiagnosed as tuberculosis. Analysis of the causes of misdiagnosis in this group are as follows: ① without making a comprehensive analysis of the history: In this longer course, performance does not match the symptoms and lesions, a history of long,[link widoczny dla zalogowanych], repeated, or died of self-healing lesion is good or bad, are valuable for the diagnosis of bronchiectasis. However, many patients in treatment, doctors at all levels did not change the overall course of analysis and assessment. ② meet the past Diagnosis: The treatment group had experienced many times, past diagnosis of admissions few doctors questioned others, and has repeatedly misdiagnosed,[link widoczny dla zalogowanych], this case is so typical. ③ insufficient basis for establishing the diagnosis of tuberculosis: 3 cases in this group simply an x-ray or clinical symptoms consistent with tuberculosis, some, not been based on etiology and CT, bronchoscopy and other tests based on to make the diagnosis of pulmonary tuberculosis , thinking one-sided, resulting in misdiagnosis. Not an objective analysis of medical technology ④ Check Results: The course of the disease appear in some cases false-positive sputum, but no further review confirmed that misdiagnosis; with x-ray findings similar to tuberculosis, the lack of images of the two signs of ability to identify disease, lead to misdiagnosis. Four cases of pulmonary alveolar proteinosis Diagnosis and Treatment of Fu Xuming (Third Hospital of Anshan City, Liaoning, Anshan 114031) Keywords: Pulmonary alveolar proteinosis; diagnosis; bronchoalveolar lavage; tomography, spiral computed; treatment CLC : R563.9 Document code: B Article ID :1002 -3429 (2008) 034) 0244) 2 alveolar proteinosis (pulmonaryalveolarproteinosis, PAP) is a lung disease of unknown etiology, characterized by alveolar accumulation of too acid Schiff (PAS) staining of lipid-rich protein. . . Clinical form. 24.2.2 Imaging Features of bronchiectasis and infection change the typical imaging increased lung markings, thickening, disorganized, not accompanied by blood vessels line the edge of a majority of films floc fuzzy shadows. ... Note the course of review, the dynamic changes observed lesions on the establishment of important reference value for diagnosis. X-ray findings in this group is among a large infiltrates showed cystic or tubular translucent film,[link widoczny dla zalogowanych], a short time after the invasion dissipated, but also thin-walled cystic visible or subtle, more regular tubular translucent areas, or in this local representation infiltrates. This phenomenon should be suspected bronchiectasis, and infection. Cystic dilatation of the bronchial isolation and infection, resembles thin-walled hollow of infection, the wall thicker and fuzzy, inflammation subsided,[link widoczny dla zalogowanych], wall thinning, but the capsule the size of the same film. CT scan not only confirms the presence of cysts, but also can help identify some of the complex circular shadow, or shadows caused by other fake bag like. Bronchiectasis, and infection can cause a wide range of inflammatory lung field infiltrates,[link widoczny dla zalogowanych], such as the emergence of massive, easily mistaken for tuberculosis hemoptysis after bronchial spread. However, after the cessation of hemoptysis, the anti-infection treatment, short-term large infiltrating melt away. 2.3 x-ray differential diagnosis should also pay attention on the non-tuberculous bronchiectasis bronchiectasis and tuberculosis identification: ① visible calcification of tuberculous bronchiectasis, fibrous proliferative lesions and lesions, lesions on the leaves of two lungs posterior tip. Non-tuberculous bronchiectasis showed lower lung texture thicker, curly hair can be seen along the bronchial-like film distribution, secondary infection can be seen the shadow of the small hair-like fluid level. Common typical tuberculous bronchiectasis or bronchial obstruction stenosis, non-tuberculous bronchiectasis often occurs terminal non-specific expansion. ② tuberculous bronchiectasis occurred in the upper lung, chicken feet were like aggregation may have a narrow lumen; non-tuberculous bronchiectasis occurred in the lower lung, and can extend to the edge of the lungs Departmen. Lung disease in this group are in the upper part, with the reported slightly different, which may be misdiagnosed as tuberculosis cases due to selective too.
