23
Q

2-3 rows of bubbles of subpleural cystic areas

A

Honeycombing

23
Q

Causes of Interstitial Pneumonias

A

Idiopathic
Collagen vascular disease
medications
inhilation

24
Q

The MOST COMMON Interstitial Lung Disease (ILD)

A

Unutual Interstitial Pneumonia (UIP)

25
Q

First finding of UIP in X ray

A

Reticular pattern in the posterior costophrenic angle

26
Q

What is the definite UIP Criteria?

A
  1. Honeycombing (must be present) +/- traction bronchiectasis
  2. Reticular abnormalities
  3. Subplerual basal predominant distribution
  4. Absence of inconsistent features:
    Upper lobe
    GG>reticulations
    Air trapping involving 3 or more lobes
27
Q

Definite UIP pattern = Biopsy?

A

Doesn’t need a biopsy to prove diagnosis.

28
Q

UIP Buzzwords!

A

Apical to basal gradient
Traction bronchiectasis
Honeycombing
Heterogeneous on Histology

29
Q

Chronic hypersensitivity Pneumonitis (HP) vs IUP

Features favoring chronic HP?

A

Air Trapping involving 3 more lobes
Mid-upper lobe predominant fibrosis

30
Q

Pulmonariy fibrosis is a risk factor for?

A

Lung CA

31
Q

Cancer in fibrotic Lung favors what lobe?

A

Lower lobes

32
Q

Cancer in fibrotic Lung favors what interface?

A

Fibrotic cysts and normal lung

33
Q

ILD that is a common pattern in collagen vascular disease, and drug reactions

A

Nonspecific Interstitial Pneumonia (NSIP)

34
Q

ILD: Homogeneous inflammation or fibrosis

A

NSIP

UIP - heterogeneous

35
Q

Two FLAVORS of NSIP

A

NSIP

42
Q

NSIP vs UIP

Presence of micronodules

A

NSIP

43

44
Q

More diffuse GGO, with patchy or subpleural distribution

A

Desquamative interstitial pneumonia (DIP)

45
Q

ILD showing Localized centrilobular ground glass nodules (due to macrophages filling up the terminal bronchioles).

A

Filling of alveolar spaces with macrophages

A

DIP
