Figure 3. Indeterminate for UIP Pattern (early UIP pattern)
(A and B) Transverse computed tomography (CT) section, (C) coronal reconstruction of both lungs,
and (D) magnified view of the right lung in supine position showing ground-glass opacity and subtle
reticulation in the subpleural areas (arrows) with a basal predominance. (E) Transverse CT section of
the lower lung zones in prone position showing persistence of lung infiltration in nondependent areas,
thus excluding gravitational abnormalities. UIP was proven at histolog y.
Figure 4. Indeterminate for UIP Pattern
(A–C) Transverse computed tomography sections
showing extensive lung infiltration combining
honeycombing, mild to marked ground-glass
opacity, asymmetrical distribution between both
lungs, and no subpleural predominance.
