The  aim  of this study was to estimate diagnostic value of virtual bronchoscopy (VB) in patients with trachea neoplasms.   Methods . Results of multidetector computed tomography with virtual bronchoscopy (MDCT"VB) were analyzed in 31 patients with neoplastic lesions of the trachea according to an original method developed in our institution.   Results.  The method allowed complete evaluation of location and extension of tumors, differentiation between benign and malignant tumors including those complicated by stenosis precluded from bronchoscopic examination. A sessile tumor with destructed underlying tissue, a rough surface, infiltrated tracheal wall, tumor extension outside the trachea, and infiltration of the mediastinum were considered as malignant signs. Similar signs were seen in metastatic lesions of the trachea from lung carcinoma: the carina and the distal trachea were injured if the tumor grew from a main bronchus, a tracheal wall was injured if a lung tumor penetrated the mediastinum.   Conclusion.  MDCT"VB appears to be the optimal diagnostic method in tumors of the trachea. In cases of trachea stenosis, MDCT"VB is the preferable method for evaluation of the tumor extension. Virtual modeling of an intratracheal tumor could help to make a decision about radical treatment.
