Diagnosis of acute diffuse pulmonary infiltrates in immunosuppressed patients by open biopsy of the lung.

Herein is a review of the results of open biopsies of the lung performed upon immunosuppressed patients between the years 1982 and 1988. The goal was to assess the safety and value of the procedure on a group of patients who are many times in extremis because of multiorgan failure. Obtaining the correct diagnosis and establishing treatment poses a challenge.
