Q

How would a CXR differ in mesothelioma vs asbestosis?

A

Mesothelioma is the cancer- associated with peripheral Masses and pleural plaques.

38
What is a radiological feature of pulmonary fibrosis?
Honeycombing
39
What makes up Lights criteria?
Protein, glucose and LDH of the pleural fluid and serum. *NB pleural pH is NOT part of lights criteria!- but still important***
40
Non small cell lung ca vs small small- treatment principles?
Non small cell= surgery! and chemo/ radio. Remember non small cell= non smokers. Small cell= chemo and radio (NOT SURGERY)
