How is lymphocytic bronchiolitis Diagnosed?

Is a lung ct or X-ray enough for a diagnosis or would a gas exchange test or a lung biopsy be needed? Also what are the symptoms and what would the tests be?

Hello and welcome to the forum.  Thanks for your question.  Are you asking for yourself or your child?  Lymphocytic bronchiolitis is a lung infection (inflammation of the bronchioles-the airways that extend beyond the bronchi and end in the alveoli) that affects the more distal airways; it is a viral inflammatory process.  Most people are diagnosed with this in childhood but has been seen in older people as well.  In the adult clinic, conventional and high-resolution radiology and respiratory functional studies are suggestive of the diagnosis but the etiology usually requires tissue.  https://www.mayoclinic.org/diseases-conditions/bronchiolitis/diagnosis-treatment/drc-20351571  So, the imaging is imperative and likely a gas exchange test but perhaps not a biopsy.  Please give us more details and let us know how you are doing.

It’s for me. I’ve been exposed to metal lubrication fluid At my workplace which is known to cause this disorder. I  I’ve had a ct of my lungs and the report doesn’t mention it. I have experienced a small pleural effusion and lung collapse, and Swollen fingertips so I’m wondering if it’s lymphocytic bronchiolitis. Would my ct and X-rays be enough for a diagnosis?
