title: Q fever inflammatory pseudotumor of the lung.
abstract: A 36-year-old man presented with malaise, myalgia, fever, and weight loss. Liver function tests were moderately abnormal and chest x-ray film revealed an irregular mass in the right lower lobe. Bronchoscopy with cytology was not helpful. Serology revealed markedly elevated titers to Q fever. The mass was presumed to represent the presence of a Q fever pseudotumor. The patient responded to therapy with resolution of symptoms and chest x-ray film and decrease in titers to Q fever.
