Respiratory bronchiolitis: an unusual cause of pulmonary infiltrates in a pregnant woman.
Numerous mechanical, biochemical, and immunologic changes occur during pregnancy. Because of these changes, pregnant women are more susceptible to infection, thromboembolic disease, exacerbation of underlying immunologic disease, and heart failure than women who are not pregnant. The differential diagnosis of diffuse pulmonary infiltrates in a pregnant woman is broad; thus, the work-up can be very challenging. If the patient fails to respond to conservative measures, such as antibiotics, the cause of the infiltrate must be aggressively evaluated because the treatment may be essential for the survival of the mother and fetus. We report a case of a pregnant woman who presented with diffuse bilateral infiltrates. After video-assisted thoracoscopic lung biopsy, this patient was found to have respiratory bronchiolitis, a disease not previously reported during pregnancy. Treatment with glucocorticoids resulted in a prompt improvement in symptoms.
