[Pulmonary nodules and arachnophobia].
Pulmonary nodules are a common reason for consultation and their investigation must always exclude a possible neoplastic cause. This means that, in addition to a thorough history, investigations may be necessary which are sometimes invasive and therefore potentially a cause of iatrogenic harm. The toxic aetiologies for pulmonary nodules are rare. We report a case of a patient with pulmonary nodules occurring predominantly in the right lung, about 1cm in diameter, non-cavitating without calcification, and sometimes surrounded by a peripheral halo. The nodules were a chance finding during preoperative evaluation. After a comprehensive review, a reaction to an inhaled irritant was the preferred hypothesis, specifically overuse of a compound insecticide containing, in addition to the propellant gas and solvent type hydrocarbon - a mixture of piperonyl butoxide, of esbiothrine and permethrin. Removal of this led to the complete disappearance of nodules. Pathological examination identified bronchiolitis obliterans with organising pneumonia accompanied by non-necrotizing granulomas and lipid vacuoles.
