Solitary pulmonary nodule--150 resected cases

Solitary pulmonary nodule represents a radiological entity with unknown prevalence in general population. As definition, solitary pulmonary nodule has 3 cm diameter or less and is surrounded by lung parenchyma, with no other abnormalities on the same chest X-ray or CT scan film. The differential diagnosis of the solitary pulmonary nodule includes over 100 conditions and the most frequent is lung cancer. Identification and correct management of the solitary pulmonary nodule opposes early detection and treatment of the lung cancer and the uselessness of a surgical procedure on a benign disease which needs no treatment. After analyzing 150 solitary pulmonary nodules resected and after comparing the results with the literature, given the fact that 48.66% of the nodules are malignant and 52.66% of the nodules have the maximum accepted dimensions (3 cm), the authors proposed an algorithm for solitary pulmonary nodule management adapted to Romania's accessibility to diagnostic procedures. As conclusion, the surgical resection of an indeterminate solitary pulmonary nodule (not certified as benign at CT scan or by biopsy) has an absolute indication and curative intention.
