Figure 6 (A and B): Tuberculosis with perilymphatic nodules and cluster sign. 36-year old man with fever, cough and progressive weight loss for 5 months. GeneXpert MTB from bronchoalveolar lavage (BAL) fluid was positive. (A) Axial high resolution computed tomography (HRCT) image shows thick-walled cavity with adjacent consolidation in right upper lobe (black arrow). Multiple adjacent coalescent ill-defined air-space nodules are noted. Smaller area of consolidation also noted in left upper lobe. (B) Axial HRCT image (at lower level) shows multiple clusters of discrete micronodules bilaterally along with nodular thickening of right major fissure suggestive of lymphatic spread (dashed arrows)
