you very much for your question.
pulmonary nodule is a round or oval spot (lesion) in the lungs
that is seen with a chest x-ray or CT scan.
than half of all solitary pulmonary nodules are noncancerous (benign).
Benign nodules have many causes, including old scars and infections.
granulomas (reactions to a past infection) cause most benign lesions.
effusion is a buildup of fluid between the layers of tissue that
line the lungs and chest cavity.
types of effusions can develop:
pleural effusions are caused by fluid leaking into the pleural space.
This is caused by increased pressure in, or low protein content in,
the blood vessels. Congestive heart failure is the most common cause.
effusions are caused by blocked blood vessels, inflammation, lung
injury, and drug reactions.
sarcoidosis may manifest with various radiologic patterns: Bilateral
hilar lymph node enlargement is the most common finding, followed
by interstitial lung disease.
CT, the most typical findings of pulmonary involvement are micronodules
with a perilymphatic distribution, fibrotic changes, and bilateral
granulomas frequently cause nodular or irregular thickening of
the peribronchovascular interstitium.
lung mass or nodule is rarely seen in sarcoidosis; however, individual
granulomas that coalesce may produce the appearance of solitary masslike
clinical contexts, multiple well-defined rounded macronodules (nodules
with diameters exceeding
5 mm) might mimic a metastatic process.
ground-glass opacities are seen in an estimated 40% of patients
with parenchymal changes due to pulmonary sarcoidosis; extensive ground-glass
opacities are much less common.
ground-glass opacities in sarcoidosis are always accompanied by other
abnormalities and often are superimposed on a background of interstitial
the presence of pulmonary sarcoidosis is suspected, diagnostic
procedures should ideally allow
(a) histologic verification,
(b) assessment of the extent and severity of organ involvement,
(c) assessment of whether disease is stable or likely to progress,
(d) determination of whether a patient might benefit from treatment.
