Calcified post-tuberculosis nodule at an unusual site

Abstract

Abstract Calcification is one of the post-treatment sequelae of pulmonary tuberculosis (TB) and an isolated calcified pulmonary nodule representing granuloma in a lung fissure is rarely detected. We report the case of pulmonary nodule with calcification within the minor fissure of the right lung in a treated case of smear-positive pulmonary TB. As an incidental finding, a solitary post-tuberculous calcified granuloma may not have clinical significance but has to be differentiated from relapse of TB and other pathologic conditions particularly neoplasms. A computed tomographic scan of the chest is very useful for the detection and detailed evaluation of a pulmonary nodule such as its size, margins, doubling time, pattern of calcification and presence of cavitation and can help to identify whether the pulmonary nodule is benign or malignant.
