Hilar adenopathy and tuberculosis.
I am going through suggested answers.
have one more question:
any chance of tuberculosis from given x ray report?
I go for TB sputum/smear test?
subtle Left Hilar Prominence noted. *
Fissure is seen Right diaphragmatic humping with bilateral scalloping
is noted *
both lung fields and pleural appear clear *
size is normal Aorta and right hilum appear normal *
thorax is normal*
diagnosis of unilateral or asymmetric hilar adenopathy includes infections
[primary tuberculosis (Primary TB, is classically described in children),
fungi such as histoplasma, and bacteria such as tularemia or anthrax]
and neoplasia (lymphoma or metastatic malignancy such as lung, breast,renal,
(TB) in adults is generally not associated with hilar adenopathy.
TB is usually due to reactivation of prior disease and is characterized
by multifocal cavitary infiltrates in the upper lobes, granuloma formation,
and healing with fibrosis.
in patients with disorders of cell-mediated immunity such as AIDS,
reactivation TB can have an appearance similar to primary TB (lobar
infiltrate and hilar adenopathy).
from a chest x-ray cannot confirm that a person has TB disease.
laboratory test is the examination of sputum for the detection of
acid-fast bacilli (AFB).
it only identifies 35% of patients with active TB.
test will also identify acid fast bacilli other than M. tuberculosis
so its specificity is not 100%.
