My 5 year old son has an extensive history including hopitalizations for pneumonia and bronchitis. I took him to the ER and his SpO2 was 94% upon arrival with a 102.3 oral temp. They stated he had decreased breath sounds and had a chest x-ray performed. He cried throughout the x-ray and was unable to hold still. They stated his x-ray came back normal however the actual report stated that he had crowded bronchovascular markings in the right infrahilar region. They placed him on Omnicef as the dx was bilateral otitis media and fever unspecified. He has been taking the abx for 4 days now. He is complaining of some chest pain and is really not getting any better. Is the bronchovascular markings to be of concern as he is not getting better?
