Pulmonary nodular lymphoid hyperplasia is a reactive lymphoproliferative disease. It is very rare, which means that many aspects of the disease are unknown or have not been proven. Pulmonary nodular lymphoid hyperplasia can be symptomatic or asymptomatic, progressive or not, and solitary or multiple, and a surgical approach is the current treatment of choice. We present a case of pulmonary nodular lymphoid hyperplasia that was visualized as multiple ground glass opacities on a computed tomography (CT) scan, and observed for 1 year because the patient was pregnant. Over this period, the number and extent of the opacities progressed, but no symptoms were reported. A surgical biopsy was done and some remaining lesions regressed on follow-up CT scans, while others progressed, without any appearance of symptoms.
