Novel Combined ectopic variation of the right upper pulmonary vein and bronchus

We report the case of a 66-year-old woman with lung cancer in which preoperative three-dimensional computed tomography reconstruction and intraoperative images displayed a novel combined ectopic variation of the RUV and bronchus. The RUV was absent from the anterior hilum, but instead was present in the superior and posterior hilum dispersedly. In addition, the right upper lobe bronchus was ectopic to the lower edge of the "bronchus intermedius". Based on this discovery, video-assisted thoracoscopic lobectomy was successfully performed.

Precise medical imaging and analysis could enable early detection of lung cancer, help determine its exact size and location, and significantly improve diagnosis and treatment. This is usually done in a process called segmentation, which uses computers to identify the boundaries of the lung from surrounding thoracic tissue on CT images. From this process, a detailed 3-D map of the airways may be generated that can help to plan and navigate a bronchoscopy procedure to obtain biopsy samples and to perform other clinical interventions. “Until now, t...

Publication date: Available online 12 August 2019Source: Respiratory Medicine Case ReportsAuthor(s): Daisuke Himeji, Gen-ichi Tanaka, Chikara Fukuyama, Atsushi Yamanaka, Ritsuya Shiiba, Sayaka Moriguchi, Kousuke MarutsukaAbstractA 70-year-old woman diagnosed with advanced, non-resectable programmed cell death ligand 1-positive-non-small-cell lung carcinoma was treated with pembrolizumab as first-line therapy. Soon after therapy initiation, she presented with severe dyspnea, and chest computed tomography revealed a soft tissue mass in the lower trachea of the right main bronchus. During bronchoscopy, she became severely hyp...

We report an unusual case of a patient with persistent cough and dyspnoea in the context of prior chemoradiotherapy for primary lung cancer who was subsequently found to have invasive tracheobronchial aspergillosis of the distal trachea and proximal of right main bronchus. Invasive tracheobronchial aspergillosis is a rare disease with most reported cases in the literature occurring in immunocompromised hosts. We report an unusual case of a patient with persistent cough and dyspnoea in the context of prior chemoradiotherapy for primary lung cancer. Chest computed tomography (CT) demonstrated an abnormal soft tissue mass sur...

In this study, the ratio of the length of the lung apex to the hilum and the length of the apex to the base of the right lung was measured using chest computed tomography (CT) at the time of the diagnosis, and the relationship with clinical parameters was investigated. We also examined the deviations of the trachea on chest radiographs and compared them with those in idiopathic pulmonary fibrosis (IPF) and early-stage lung cancer. Thirty-eight PPFE patients in a previous study included 20 patients who simultaneously showed the lower lobe lesions. The median ratio of the length of the apex to the hilum/apex to the base was ...

Conclusions: As compared to 3DCT, 4DCT scans deliver more organ doses, especially for pediatric patients. Substantial increase in lung cancer risk is associated with higher radiation dose from 4DCT and smaller patients' size as well as younger age. PMID: 30345309 [PubMed - in process]

Conclusion: An iterative thresholding method for automatic lung segmentation has been described, capable of producing lung VOIs with DSCs comparable to the results of atlas segmentation with multiple best matches. This permits individuals without access to atlas segmentation methods to accurately and automatically generate lung VOIs. Reference: Pirozzi S, Horvot M, Piper J, Nelson AS.

Over the last half century, technology has made possible the probing of the solar system and galaxy beyond. People can instantly correspond with anyone in the world. We can see —in real time—events and phenomena heretofore only reported by second and third hand accounts. Yet with all of the distance breached by modern devices, we are also able to know in detail the goings on inside our own bodies. With the advent of computed tomography (CT) imaging, known familiarly as “CAT scans,” doctors and their patients now get a bird’s eye view of internal organs. This scientific know-how goes beyond sim...
