More Information
The clinical presentation, including the history of cough, headache, shortness of breath, fever, and presence of cold agglutinins along with the chest X-ray findings suggests a diagnosis of atypical pneumonia. Cold agglutinin titers are often associated with Mycoplasma pneumoniae, a common cause of atypical pneumonia.
Tips
A common mistake might be to choose streptococcal pneumonia due to the productive cough, but cold agglutinin titers are more specific to atypical causes.
