A patient presents with a cavitatory lesion in right upper lobe of lung. The best investigation is?
Branchoscopy, lavage and brushing
C.T. Scan
X ray
FNAC
Answer is A (Bronchoscopy, lavage and brushing) : The basic idea is to obtain a tissue biopsy. FNAC could he used, however it would ceainly not be the best. Bronchoscopy would allow, both, direct visualization and biopsy, and so is the best option here.
