There is reticulation or a network of fine lines that resembles a net or mesh on the CT scan. It's usually a sign of interstitial lung disease (ILD). There is also architectural distortion, ground glass (hazy areas, red arrows in figure 1), and traction bronchiectasis (irregular widening of the bronchi and thickened bronchial walls, yellow arrows in figure 1). There are no pulmonary nodules noted. The pulmonary function testing results are shown in table 1.

Table 1. Results of pulmonary function testing (PFTs).

The connective tissue disease panel showed-

• Rheumatoid factors: 15 (nl <15)
• Anti-cyclic citrullinated peptide (anti-CCP): negative

• Remainder of CTD serology negative
