The thin section MSCT of this patient shows a definite usual interstitial pneumonia (UIP) pattern with the following features: 
  • Traction bronchiectasis
  • Honeycombing
  • Reticulation
It is important to note that although this patient shows a definite UIP on the MSCT, the underlying disease is not idiopathic pulmonary fibrosis. The dilated oesophagus points to systemic sclerosis.
