Thanks for your question on Health Care Magic. I can understand your concern. Increased bronchovascular markings are seen in bronchitis or viral infection. It is not suggestive of pneumonia. It suggests inflammation. Normally, airways are black and not seen clearly on chest x ray. They appeared black on x ray. But due to inflammation, airway walls are edamatous and blood supply in adjacent vessels is also increased. So airways and vessels become prominent on chest x ray and hence it is known as prominent bronchovascular markings. So it is not first stage of pneumonia. It is inflammed airways. If your daughter is having severe cough, breathlessness, wheezing, fever, chest pain etc than admission is needed. Hope I have solved your query. Wishing good health to your daughter. Thanks.
