case_images: Imaging examination revealed situs inversus totalis, bronchiectasis predominantly in the left middle lobe, and sinusitis (Figure 1a-c). The CT scan of the paranasal sinuses showed thickening of the outer wall of the right maxillary sinus with unevenly increased density, suggesting a possible combination of fibrous dysplasia of bone. (Figure 1a) His nasal nitric oxide (nNO) was 7.2 nL/min, and during the 1-year follow-up when his respiratory symptoms were stable, the repeated nNO measurement was 19.3 nL/min, both significantly below the 77 nL/min threshold (Shapiro et al. ).
