  • Title: Central lung masses: prediction with CT of need for pneumonectomy versus lobectomy.
    Author: Quint LE, Glazer GM, Orringer MB.
    Journal: Radiology; 1987 Dec; 165(3):735-8. PubMed ID: 3685352.
    Abstract:
    To assess the possible role of computed tomography (CT) in predicting the need for pneumonectomy rather than lobectomy, the authors retrospectively analyzed the CT scans of 26 patients requiring pneumonectomy (n = 21) or lobectomy (n = 5) for resection of central pulmonary abnormality. Twenty-three patients had primary lung cancer, two had metastatic carcinoma, and one had a massive granuloma. Scans were evaluated for tumor involvement of bronchi and pulmonary arteries and veins and for evidence of tumor extension across a fissure. Findings were compared with detailed surgical and pathologic data. Pneumonectomy was necessary most commonly because of proximal bronchial tumor invasion (13 patients). CT showed poor sensitivity (50%-54%) in depicting central bronchial and central pulmonary artery involvement as well as transfissural tumor extent. The results suggest that CT is not highly accurate in predicting the lobectomy/pneumonectomy decision in patients with central lung masses.
