Does this patient have a UIP pattern?
While the honeycombing and traction bronchiectasis are in keeping with a UIP pattern, the extensive ground gas opacity and gas trapping is not. These changes do not meet HRCT criteria for UIP.
Reticular opacity and honeycombing in a mainly basal and peripheral distribution. Traction bronchiectasis in the bases. Widespread ground glass opacity. Gas trapping on expiratory images. Emphysematous changes at the lung apices.
No pleural effusion. No lymphadenopathy.
