Table 4 Chest CT scan findings in patients with DIPNECH vs. patients with other diagnoses

From: Is the combination of bilateral pulmonary nodules and mosaic attenuation on chest CT specific for DIPNECH?

Characteristic DIPNECH
N = 5
Other diagnoses N = 46
Number of nodules
 2–3 0 (0) 7 (15)
 4–5 0 (0) 3 (7)
 6–10 1 (20) 12 (26)
 > 10 4 (80) 24 (52)
Nodule density
 Solid only 4 (80) 29 (63)
 Solid and subsolid 1 (20) 17 (37)
Lobar predominance
 Upper lobes 0 (0) 3 (7)
 Lower lobes 0 (0) 2 (4)
 Random 5 (100) 41 (89)
Peribronchial distribution** 4 (80) 10 (22)
Bronchial wall thickening 5 (100) 31 (67)
Masses present 0 (0) 5 (11)
Diameter of largest nodule/mass (mm); median (range) 7 (4–30) 8 (3–69)
  1. Data are presented as N (%) unless otherwise specified
  2. DIPNECH: diffuse idiopathic pulmonary neuroendocrine cell hyperplasia
  3. Subsolid attenuations include ground-glass, and part-solid attenuations
  4. **Signifies p-value < 0.05
