[Table/Fig-4]:

(a) Plain radiograph posteroanterior view chest of a 56-year-old female patient on cancer chemotherapy showing consolidation-cavitation with air crescent in right upper lobe suggestive of fungal ball with possibly invasion. (b) CT thorax of another 29-year-old male patient with angioinvasive aspergillosis who underwent a renal transplant showing a nodular lesion in left lung with central hypodensity (arrows). The “Hypodense sign” preceding the formation of air crescent is a less sensitive but highly specific sign for fungal infection.
