- 1. HRCT Basics of UsualInterstitial Pneumonia E-Poster presentation by - Dr. Vaibhavkumar Vekaria (Resident doctor) Under guidance of – Dr. Nalin G. Patel Professor & H.O.D. of Radiology dept. Dr. M.K. Shah Medical college.
- 2. (A) UIP pattern (Givenin 2018 update of ATS/ERS classification) • 1. Honeycombing with or without traction bronchiectasis (hallmark). • 2. Reticular abnormality • 3. The typical sub-pleural and basal predominance
- 3. Honeycombing with sub-pleuraland basal predominance - Definite UIP pattern
- 4. Probable UIP pattern •Absent honeycombing • Reticular abnormalities • Peripheral tractional bronchiectasis or bronchiolectasis • Typical distribution: Sub-pleural and basal predominance
- 5. • Reticular pattern •Peripheral bronchiolectasis with sub-pleural & basal predominance • Absence of honeycombing.- Probable UIP pattern
- 6. Indeterminate for UIPpattern • Subtle reticular abnormalities with/without ground glass opacification superimposed on a fine reticular pattern. • Non specific distribution • Does not explicitly suggest an "alternative diagnosis”.
- 7. • Ground-glass opacity •Subtle reticulation in the subpleural areas with a basal predominance - Indeterminate for UIP pattern
- 8. Alternative diagnosis forUIP • Upper or mid lung predominance • Peri-broncho-vascular or Peri-lymphatic distribution • Marked mosaic attenuation • Predominant ground-glass opacification • Profuse micro-nodules • Pleural Effusion • Pleural Thickening or plaques
- 9. Case: 64Y /Male patient •C/O shortness of breath • On ambulatory O2 therapy • H /O chronic bidi smoking • On lab. Reports – elevated D-DIMER
- 10. •Patchy ground glassopacities •Microcystic honeycombing •Reticular pattern •Parenchymal Distortion •Subpleural and basal distribution - Fibrotic Usual Interstitial Pneumonia (UIP) likely
