Pulmonary tuberculoma and indications for surgery: radiographic and clinicopathological analysis

Tuberculomas of the lung are one of the more common lesions presenting a solitary pulmonary nodule, roentgenographically. We treated 36 patients with such nodules and describe here the radiologic-pathologic correlations and surgical treatment. In 21 patients, lung cancer was suspected preoperatively, based on radiographic findings of an ill-defined margin, pleural indentation and spicular radiation. Histologically, the tuberculous granuloma proliferated in the alveolar septa of the surrounding normal lung, often seen as a spicular radiation resembling lung cancer. In eight patients, tuberculoma was suspected because of radiographic findings of calcification and satellite nodules, and anti-tuberculous chemotherapy was prescribed for a few months. As this treatment was ineffective, surgical resection had to be done. Postoperative complications were nil and all of these patients are doing well at the time of preparation of this report. Anti-tuberculous chemotherapy was prescribed for 28 of 36 patients, postoperatively. We believe that surgical intervention is required for selected patients.
