  ABSTRACT: The development of CT scanning has been beneficial for clinical medicine. In this case, virtual bronchoscopy (VB) was of clinical benefit. A 71-year-old woman with suspected lung cancer in the upper left lobe remained undiagnosed after investigation at another hospital. VB was used to confirm the location of the tumour, which facilitated an appropriate trans-bronchial lung biopsy being performed. The volume-rendering technique yielded information regarding an arterial anomaly, allowing high-quality and safe medical treatment to be provided. VB assists navigation in bronchoscopy, and the volume-rendering technique is effective in finding congenital anomalies of the vessels during preoperative assessment.

  ABSTRACT: Occasionally, we have difficulty in diagnosing small peripheral pulmonary nodules. However, efforts have been made to resolve this problem. For instance, computed-tomography (CT), positron emission tomography (PET), flexible bronchoscopy examination (BF), and video-assisted thoracic surgery (VATS) have been performed to investigate such nodules. We have used endobronchial ultrasonography with a guide-sheath (EBUS-GS) for BF examination, and recently applied the virtual reality technique "virtual bronchoscopy (VB)". Here, we present a case in which a combined technique with VB and EBUS-GS was useful. The patient was a 54-year-old man with a persistent cough and chest pain. Small nodules were seen in the bilateral lungs on the chest CT taken at the local hospital. A slight increase in the CEA level (6.1 ng/ml; normal level < 5.0 ng/ml) was shown as well as an uptake in the latter term on PET. As a result, he was referred to our hospital for a detailed work-up. We applied VB to confirm the location of the tumor, which allowed us to approach the lesion easily. Furthermore, we precisely localized the lesion using EBUS-GS. Then a biopsy was performed, which demonstrated bronchiolitis obliterans organizing pneumonia (BOOP). As seen in this case, combining VB and EBUS-GS seems beneficial for diagnosing peripheral pulmonary nodules.
