Inflammatory pseudotumors of the lung are uncommon in the thoracic surgical
literature. These masses resemble carcinoma of the lung radiographically a
nd are discovered only at time the of histologic review of the resected spe
cimen. We report a case of inflammatory pseudotumor that was excised withou
t pulmonary resection, although it completely filled the Fight hemithorax.
We think it was the greatest inflammatory pseudotumor in the English litera
ture.
