Aims: To evaluate the ethiological rate of pulmonary nodules, in Clinic of Pulmonary Diseases from Iasi, between 1st January 2002-31th December 2004. Matherial and Methods: A retrospective study included 1881 patients with ages between 13 and 89 years, with clinical diagnostic compatible with radiological patterns like pulmonary nodules. We observed the localisation of pulmonary nodules, the morphological characteristics, size and the radiological signs of association. Results: Ethiological repartition of the frequency was: lung cancer 41.84%, pulmonary tuberculosis 23.2%, lung absces 11.9%, hydatid cyst 11.32%, pulmonary metastases 4.6%, pulmonary nodules of unknown ethiology 4.41%, round pleural efussion 1.15%, pulmonary aspergillosis 0.38%, bronchogenic cyst 0.38%, pleuro-pericardic cyst 0.38%, benign tumors 0.19%, tumors of thoracic cage 0.19%. Conclusions: Males under 40 years have tuberculosis nodules on the first place (48.5%), followed by hydatid cyst 25.7%, abscess 12.8%, lung cancer 5.7% and metastases 1.4%. Female under 40 years have this etiology for the pulmonary nodules: tuberculosis(55.5%), hydatid cyst (14.8%), metastases (9.2%), lung cancer (7.4%) and abscess (5.5%) Males with more than 40 years: lung cancer on the first place (59.8%), abscess (14.3%), tuberculosis (13.4%), hydatid cyst (6.5%); similar with the females aged more than 40 years: lung cancer(29.7%), tuberculosis (18.6%), hydatid cyst (6.5%) and abscess (6.6%)
