Primary pulmonary tuberculosis can involve regional lymph nodes which may resolve spontaneously or on treatment; or they may enlarge causing extrinsic bronchial compression; or cause endobronchial inflammation and ulceration; or a node may erode through the bronchial wall with extrusion of caseous materials into the bronchial tree, causing focal or lobar pneumonia. This erosion is seen radiologically as hilar lymphadenopathy, with atelectasis and consolidation and described as â€śepituberculosisâ€ť. It is more common in infants than older children. We hereby describe the case of a 13-year-old child with right hilar lymphadenopathy and right upper lobe consolidation on chest x-ray. We demonstrated by fibreoptic bronchoscopy that this epituberculosis resulted from perforation of a lymph node and discharge of caseous material into the upper lobe bronchus with resultant endobronchial obstruction. Thus a tuberculous ruptured lymph node may lead to clinical and radiological worsening, but this does not indicate development of drug resistance in these patients and they respond well to the same treatment regimen.
