Surgical outcome of inflammatory pseudotumor in the lung

Abstract

Background: Pulmonary inflammatory pseudotumors are rare, and little is known about their clinical behavior and surgical outcome.

Materials and methods: Between 1993 and 2003, 19 patients with inflammatory pseudotumor were managed in our hospital. We retrospectively reviewed the clinical and radiographic features, as well as the surgical outcomes.

Results: Of the 19 patients (15 men, 4 women; mean age 53.9 years), 6 underwent lobectomy, 11 had wedge resections, and 2 had biopsy alone. There was no recurrence of the lesion in the 17 patients who underwent resection or lobectomy of the pseudotumor. There was no disease progression in the 2 patients who had only had a biopsy.

Conclusion: Inflammatory pseudotumor of the lung is relatively benign. Complete resection leads to an excellent outcome.
