Fiberoptic bronchoscopy (FOB) is one of the important modalities in helping to uphold the diagnosis and stadium of bronchogenic carcinoma. However, FOB has some limitations, namely invasive, time-consuming, requiring sedation, intolerable in patients who are critically ill, and difficult to evaluate distal airway side of severe stenosis. To identify the imaging capability of virtual bronchoscopy (VB) examinations in evaluating abnormalities in the tracheobronchial in bronchogenic carcinoma. Observational study with total sampling. Data was obtained from the histopathologic with diagnosis of bronchogenic carcinoma in 1 year. Retrospectively, the data were obtained from the archives of thoracic CT examinations in Radiology and FOB examination in Lung Operating Room. The variables assessed were the finding of mass of endobronchial based on its location, the main bronchi constriction, lobar bronchi constriction, segmental bronchi constriction, and compression/tracheal deformity. The results of VB were examined by three radiologists independently and were then compared with the results of FOB. The observation results of VB and FOB were used to analyse the degree of conformity. There is a low level of agreement on the finding of endobronchial mass, lobar bronchi and segmental bronchi constriction, sufficient level of agreement on the main bronchial constriction finding. VB has a limited capacity to evaluate abnormalities of the tracheobronchial compared with FOB, but VB has an advantage in evaluating the patency of the distal airway of severe obstruction.

Abstract Background Although drug-induced interstitial pneumonia is a well-known adverse side-effect of cancer chemotherapy, the disease is difficult to detect in the early phase. We report a case of oxaliplatin-induced interstitial pneumonia in which eosinophilia and high-grade fever with relative bradycardia were useful presenting signs for the early diagnosis. Case presentation A 76-year-old Japanese woman with postoperative recurrent rectal cancer (peritoneal dissemination and liver metastasis) was admitted to our hospital because of productive cough and consolidation on thoracic computed tomography (CT) images. Two months prior to the consultation, she had started chemotherapy (fluorouracil, oxaliplatin, and bevacizumab). After finishing three courses of chemotherapy, she developed fever and was noted to have relative bradycardia. After another two courses of chemotherapy, she developed productive cough, chest discomfort, and high-grade fever. At this time, thoracic CT revealed patchy areas of consolidation distributed predominantly in the periphery. Despite the administration of tazobacterium/piperacillin, the consolidation seen on CT scans gradually worsened. Fiberoptic bronchoscopy was performed, and bronchoalveolar lavage fluid analysis showed increased lymphocytes, eosinophils, and total cell count but a low CD4/ CD8 ratio. No specific pathogen was identified. With a diagnosis of interstitial pneumonia, prednisolone was started and chemotherapy was temporarily discontinued. Her productive cough gradually decreased, and the infiltrative shadows on the thoracic CT scans improved. Conclusion Although cases of oxaliplatin-related pneumonia with complicating relative bradycardia are not uncommon, drug-induced interstitial pneumonia should be taken into account in the differential diagnosis. In this case, an increased circulating eosinophil count and high-grade fever with relative bradycardia were the first signs of drug-induced interstitial pneumonia.

Introduction/Objective. Fiberoptic bronchoscopy often is too aggressive, which requires the use of other noninvasive diagnostic methods. The study presents research results on the diagnostic capabilities of virtual bronchoscopy with multidetector computed tomography and fiberoptic bronchoscopy in traumatic abnormalities of trachea and main bronchi. Methods. A total of 21 patients (six males and 15 females) at the ages of 11?82 years (50.65 ? 19.8) were studied by the methods of virtual bronchoscopy with multidetector computed tomography and fiberoptic bronchoscopy. The diagnostic capabilities of virtual bronchoscopy as compared to fiberoptic bronchoscopy were assessed by established criteria. Results. Ruptures of the trachea and/or bronchi were proven by fiberoptic bronchoscopy in 21 patients and by virtual bronchoscopy in 19 patients. The greatest frequency was reported for the post-intubation ruptures (15 patients, 71.42% with virtual bronchoscopy; 16 patients, 76.19% with fiberoptic bronchoscopy), followed by post-traumatic ruptures (three patients, 14.29%); ruptures of trachea and the left lower lobar bronchus as a result of an advanced neoplasm of the esophagus (one patient, 4.76%), diagnosed by both methods; mucosal erosion after instrumental manipulations (4.76%, after fiberoptic bronchoscopy). Conclusion. Achieved diagnostic accuracy in ruptures of trachea and bronchi by virtual bronchoscopy is 90.47% and by fiberoptic bronchoscopy it is 100%. In terms of localization, shape and size, almost complete correspondence of changes with those of fiberoptic bronchoscopy was found. The presence of abundant secretion in virtual bronchoscopy may be interpreted incorrectly and efficiency of virtual bronchoscopy decreases.

Tomography Data

A broad spectrum of pathologies that involve the laryngotracheobronchial airway and imaging plays a crucial role in evaluating these abnormalities. Computed tomography with virtual bronchoscopy has been found to be very helpful in defining the location, extent, and nature of these lesions, and is increasingly being used even in patients with contraindications for fiberoptic bronchoscopy and laryngoscopy. Ionizing radiation, associated with virtual bronchoscopy, can be minimized by using low-dose multidetector computed tomography and hybrid iterative reconstruction techniques. Furthermore, retrospectively generated virtual bronchoscopy from a routinely acquired computed tomography data set eliminates additional cost and radiation. In the future, virtual bronchoscopy assisted with advanced navigational techniques will broaden the diagnostic and therapeutic landscape. This article presents the characteristic features of common and rare laryngotracheobronchial pathologies seen with virtual bronchoscopy.

Visual Range

— Of 1,000 consecutive patients undergoing fiberoptic bronchoscopy, 331 eventually were proven to have primary lung cancer. Of the 331 carcinomas, 253 were beyond the visual range of the flexible bronchoscope. However, under fluoroscopic guidance, the diagnosis of carcinoma was established in 194 (76.7%) of these nonvisualized tumors. Cytologic analysis of brush specimens was more often positive for malignancy than specimens obtained by forceps biopsy. An expert cytologist and experienced bronchoscopy team are essential for a high percentage of reliable positive diagnoses in bronchogenic carcinoma.

The aim of this study was to compare different representation models of surface-rendered virtual bronchoscopy. 10 consecutive patients with inoperable primary lung tumors underwent thin-section spiral computed tomography. The structures of interest, the tracheobronchial system and anatomical and pathological thoracic structures were segmented using an interactive threshold interval volume-growing segmentation algorithm and visualized with the aid of a color-coded surface rendering method. For virtual bronchoscopy, the tracheobronchial system was visualized using a triangle-surface rendering model, a shaded-surface rendering model and a transparent shaded-surface rendering model. The triangle-surface rendering model allowed optimum detailed spatial representation of the dimensions of extraluminal anatomical and pathological mediastinal structures. As the lumen of the tracheobronchial system was less well defined, the rendering model was of limited use for depiction of the airway surface. The shaded-surface rendering model facilitated an optimum assessment of the airway surface, but the mediastinal structures could not be depicted. The transparent shaded-surface rendering model provides simultaneous adequate to optimum visualization and assessment of the intraluminal airway surface and the extraluminal mediastinal structures as well as a quantitative assessment of the spatial relationship between these structures. Fast data acquisition with a multi-slice detector spiral computed tomography scanner and the use of virtual bronchoscopy with the transparent shaded-surface rendering model obviate the need for time consuming detailed analysis and presentation of axial source images by providing improved the diagnostic imaging of endotracheal and endobronchial diseases and offering a useful alternative to fiberoptic bronchoscopy.
