Cryptococcal antigen testing of lung tissue homogenate improves pulmonary cryptococcosis diagnosis: Two case reports

Figure 1 Imaging, pathology and cryptococcal antigen testing of lung tissue homogenate of case 1. A: Computed tomography scan of the chest showing multiple nodules in both lungs (arrow); B: Ink staining of lung biopsy specimen showing polysaccharide capsule that surrounds the cell body; C: Results of cryptococcal antigen lateral flow immunoassay of lung tissue homogenate.

Figure 2 Imaging, pathology and cryptococcal antigen testing of lung tissue homogenate of case 2. A: Computed tomography scan of the chest showing a nodule in the right lung (arrow); B: Positive result for cryptococcal antigen in lateral flow immunoassay of lung tissue homogenate; C: Ink staining of lung biopsy specimen showing polysaccharide capsule that surrounds the cell body.
