“…Although conventional CT in patients with bronchial pathology was shown to be 63-85% sensitive in detecting airway abnormalities, it was shown to be relatively inaccurate in differentiating mucosal abnormalities, intra-and extraluminal tumour [18]. Magnetic resonance imaging was found to be inferior to CT, with a 50% detection rate for bronchial abnormalities [19]. The use of HRCT to evaluate very small bronchial abnormalities in patients with haemoptysis is obvious [20].…”

In patients with so-called roentgenologically occult intraluminal lung tumours, an accurate assessment of tumour size, its location and peribronchial tumour extent is important prior to any intraluminal bronchoscopic therapy (IBT) with curative intent.In twenty patients with so-called occult early-stage lung cancers, clinical outcome was compared to high resolution computed tomography (HRCT) findings prior to IBT.HRCT showed peribronchial tumour extension or nodal enlargement in 7 of the 20 patients (35%), and consequently treatment policy was changed. Five of the seven died 1.5-6 months after diagnosis, one patient underwent a radical pneumonectomy after induction chemotherapy, and the remaining patient is alive with pleural metastasis. HRCT showed intraluminal tumours in 11 of the 20 patients and IBT with curative intent was given. Complete response (CR) was achieved in 10 of the 11 patients, follow-up has been 4-26 months. One patient underwent a radical lobectomy, pathological stage T1N0, after 3 months because of tumour recurrence. HRCT was inconclusive in 2 of the 20 patients with postobstructive infiltrates. IBT was unsuccessful in both these cases.High resolution computed tomography may provide supportive evidence of intraand extraluminal tumour; thereby, helping in the assessment of patients who were judged to be suitable for intra-luminal bronchoscopic therapy with curative intent. This may lead to a change in the treatment policy.High resolution computed tomography findings are complementary to bronchoscopic, histological and cytological examinations for the proper evaluation of treatment indications in patients with occult lung cancer.

“…Furthermore, single or multiple small nodular lesions other than the main metastatic lesion were correctly diagnosed by CT in 4 cases, while only 2 of these 4 were diagnosed by chest radiography. CT is therefore useful for identifying hilar and mediastinal lymphadenopathy (17,18,23) as well as small pulmonary nodules.…”

CT Findings of Endobronchial Metastasis

One hundred and sixty-one patients with pulmonary métastases were studied with CT. Six of them proved to have endobronchial (intraluminal) metastatic lesions by bronchoscopy. Retrospective analysis of the CT studies showed obstruction and /or narrowing of the bronchi in 5 cases while no lesion was observed in one patient. Although CT can not always demonstrate intraluminal lesions, it should be performed when an endobronchial metastasis from extrathoracic malignancy is seen by bronchoscopy because it will show hilar or mediastinal lymphadenopathy, or single or multiple pulmonary métastases other than the endobronchial lesion.

“…Also, CT scanning of the thorax is a very sensitive method for detecting pulmonary tumours. In two recent studies, abnormalities were seen in the lung parenchyma or bronchi in 9698% of primary pulmonary malignancies (Henschke et al 1987;Mayr et al 1987).…”
