Roentgenographs localization of adult reactivation pulmonary tuberculosis to the anterior segment of either or both upper lobes rarely has been reported in the recent literature. This is contrary to reports of childhood or adult primary pulmonary tuberculosis in which disease is not uncommonly described in this location. In a series of 142 adults with pulmonary tuberculosis seen over a five-year period at this insti­tution, nine patients were noted to have an initial radiologic lesion localized either solely or predomi­nantly to the anterior segment of either or both upper lobes. Five of these patients had evidence of postpri­mary or reactivation tuberculosis. This report dem­onstrates that upper lobe anterior segment infiltrates may occur in adult pulmonary tuberculois, including reactivation forms of the disease. revatio online
