The authors present a case from a 59 years old white female Brazilian patient, based in Salvador-Bahia, Brazil's northeastern side area, who experienced irritative cough and progressive dyspnea, and, after 18 months, was admitted to a hospital with respiratory insufficiency. The physical exam showed diffuse rales in both hemithoraces. Initial leukogram showed 14,400 cells/mL with 14% of eosinophils and chest X-ray showed peribronchovascular infiltrate, predominating in the lower half of the lung fields, and small opaque nodules. The high-resolution computed tomography scan of the chest (HRCT) presented compatible pattern with airways disease, especially from the small airways, with air trapping, tree sprouting images, central lobular nodules and bronchiectasis, making the results compatible with bronchiolitis and bronchiectasis. The transbroncho biopsy unveiled granulomatous lesion with necrosis, where was noticed a structure compatible to a parasitic case, and the research of the parasite eggs in the sputum was positive to paragonimus. After the praziquantel use, the patient presented a thick ferruginous expectoration and the result for BAAR examination was positive. The PCR exam and the sputum culture confirmed M. tuberculosis, and then the treatment for M. tuberculosis was initiated. The authors warn that this infection may have been a consequence of economics globalization process, where the importation of parasitized crustaceans might be the cause. However, there is the need of an accurate examination for the possibility of paragonimus specimens in this area of Brazil.
