A pulmonary tuberculoma is one of the most common causes of a solitary pulmonary lesion. Treating a tuberculoma is still controversial and there are few reports on antituberculosis chemotherapy. In this study, the clinical findings and changes in the size of tuberculomas on a radiograph after completing antiuberculosis chemotherapy was investigated. METHODS: The medical records, an chest radiographs of 18 pulmonary tuberculoma patients who were admitted to the Gachon medical school, Ghil medical center between April 1998 and August 2001, were reviewed. The symptomatic changes were recorded and the size of the tuberculomasl following treatment were compared. To compare the size, the long distance of each tuberculoma on the chest radiographs were measured and the additional radiological findings of calcification, satellite nodules and cavities were investigated. RESULTS: Fifteen patients were men and 3 were women. The median age was 46(24-74). Among these 18 patients, 14 patients had clinical symptoms. The other 4 patients were diagnosed incidentally as during a routine chest radiograph. The mean size of the tuberculomas on the initial plain chest film was 4.3+/-2.3cm(range : 1.7-10cm)and after 6 months treatment, it had decreased to 1.68+/-2.00cm(range : 1.5-6.5cm)(P<0.05). At least 6 months of antituberculosis chemotherapy resulted in the findings of a tuberculoma with a disappearance in 9, a decreased size in 4, and no change in 5 on the chest radiograph. Calcifications were found in 3 patients on the initial chest film and the chest CT and all calcified tuberculomas had disappeared after treatment. CONCLUSIONS: A lthough a pulmonary tuberculoma can remain as an inactive lesion for a long time, if it is confirmed by pathological or bacteriological methods, antituberculosis chemotherapy will be beneficial despite the presence of calcification.
