Pulmonary nodulosis

Last update 17/06/2026

(Fr: nodulose pulmonaire). Rapide development or increase in size of rheumatoid lung nodules. This pattern is restricted to the rheumatoid arthritis patient. It is is the form of new nodules or the rapid increase in size and/or cavitation of preexisting rheumatoid nodules that are temporally associated with exposure to a drug. The role of medications is unclear. Other etiologies (lung cancer, tuberculosis or another infection, lymphoproliferation) must be carefully excluded using history, FOB, PET-scan and biopsy, when and where needed. See also under XIo
