Severe pulmonary tuberculosis complicated with insidious pulmonary thromboembolism: a case report and literature review

Figures

• 

  Fig. 1. Chest CT confirmed severe pulmonary tuberculosis at admission. Large pieces of density-increased shadow and air bronchogram appeared in the upper right lung (a). The small patch of consolidation in the sub-pleura existed in the left lung, where there were small caves indicated by arrow (b). In the right lower lung lesion, there was a thin-wall cave, as well as pachynsis and adherence of pleura (c). There were neither obvious enlarged lymph nodes in the mediastinum nor the hilar on both sides. The heart shadow was not large, and no effusion or pleural thickening was observed in the chest

  Fig. 2. CTPA confirmed PTE after 15 days of treatment. Signs of filling defects were found in the left pulmonary artery, as well as the trunk and branches of right lower pulmonary arteries

• 

  Fig. 3. Comparison of pulmonary artery imaging before and after thrombolytic therapy. Pulmonary angiography revealed a filling defect in the left pulmonary artery with poor branch imaging before therapy (left panel). Through a thrombolytic therapy including mechanical thrombolysis, aspiration and pulmonary artery local urokinase thrombolysis, the filling defect of left pulmonary artery disappeared (right panel). The left pulmonary artery trunk and branches were indicated by a circle
