An accessory cardiac bronchus (ACB) is a rare congenital anomaly of the trachobronchial tree. It rarely presents with symptoms, and is usually diagnosed incidentally by chest CT, bronchoscopy, or during surgery. We experienced a case of accessory cardiac bronchus found incidentally in the bronchus intermedius with lung cancer in the right lower lobe, and surgically removed.

We have experienced a case of communicating bronchopulmonary malformation. A 35-year-old female patient was admitted for coughing with sputum. About eight years ago, she had treated for bronchiectasis with medication. Chest computed tomography revealed esophagopulmonary communication with upper esophageal dilatation and bronchiectasis of the left lower lobe. A about 3 mm diameteded abnormal feeding vessel from descending thoracic aorta to the left lower lobe was detected at operation. Division and closure of the communication between the esophagus and left lower lobe was performed. Communicating bronchopulmonary malformation is the rare form of pulmonary sequestion and chest computed tomography is one of the useful diagnostic methods for pulmonary sequestion.

Primary malignant fibrous histiocytoma of the lung is extremely rare, A 12-year-old child was admitted to the hospital due to an incidentally detected lung mass. A $2.5{\times}2.5 cm$ sized mass located in the right lower lobe was seen on the chest X-ray, the chest computed tomogram and the positron emission tomogram. We resected the mass through a right lateral thoracotomy and the mass was revealed to be a malignant spindle cell neoplasm on the frozen section diagnosis. So, we performed lobectomy of the right lower lobe with systemic dissection of the mediastinal lymph nodes; the final histopathological diagnosis of the mass was malignant fibrous histiocytoma. The patient was discharged on postoperative day 7 and adjuvant chemotherapy was not applied.

Purpose We evaluated the risk factors for progression to chronic complicated bronchopleural fistula (BPF) after pulmonary resection using follow-up CT. Materials and Methods We retrospectively reviewed 45 cases with BPF that had undergone pulmonary resection during 2010-2018. We compared the clinical and radiological characteristics of those with complicated BPF (n = 24) and those without complicated (sterilized) BPF (n = 21). The clinical and radiological risk factors for progression to chronic complicated BPF were examined by logistic regression analysis. Results The thickness of the pleural cavity wall (p = 0.022), the size of the pleural cavity (p = 0.029), and the size increase of BPF on follow-up (p = 0.012) were significantly different between the two groups. The risk factors for progression to chronic complicated BPF were age > 70 years (odds ratio, 6.43; 95% confidence interval, 1.2-33.7), the thickness of the cavity wall > 5 mm (odds ratio, 52.5; 95% confidence interval, 5.1-545.4), and an increase in the size of the pleural cavity on follow-up CT (odds ratio, 12.5; 95% confidence interval, 2.1-73.5), only in the univariate analysis. Conclusion The risk factors for progression to chronic complicated BPF can be evaluated using follow-up CT.

Bronchopulmonary endometriosis is a rare cause of hemoptysis. We describe a woman with recurrent hemoptysis during menstruation. The site of origin of hemoptysis was localized on chest CT images. CT appears to be the method of choice for the correct intrapulmonary localization of this disease. The hematogenous spread from the pelvis to the lungs has been proposed for the mechanism for the development of parenchymal pulmonary endometriosis. Thoracic endometriosis is reviewed and new therapeutic modalities are discussed.

We experienced a case of upper esophageal leiomyoma successfully excised by thoracoscopic surgery. A 29-year-old male was presented with retrosternal discomfort and mild dysphagia and an esophagogram revealed smooth fElling defect In the upper third of the intrathor cic esophagus, and esophagoscopy showed a submucosal tumor without mucosal infiltration. Chest CT and MRI were performed to confirm size, character and location of the esophageal mass, the absence of infiltration of surrounding structures, and to define mediastinal Iymphadenopathy. The tumor was excised by thoracoscopic surgery and it was diagnosed as leiomyoma (4$\times$2xlcm in size). The postoperative course was uneventful.

Coronavirus disease 2019 (COVID-19) is spreading rapidly around the world. Several articles have so far reported on radiological findings of COVID-19 pneumonia. Herein, we present three cases of COVID-19 pneumonia in South Korea, and provide clinical information as well as chest radiograph and chest CT findings.

Leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumor. Yet tumors of a smooth muscle origin are the most common primary neoplasms of the major veins, and the inferior vena cava is the most common site of origin. We report here on a 65-year-old female patient who had been suffering from dyspnea and abdominal discomfort for 3 weeks before admission. The abdominal computed tomography (CT) scan and IVC cavogram showed an IVC mass extending from the right atrium to above the level of the right renal vein, obstructing the IVC, and the radiological findings were suggestive of an IVC leiomyosarcoma. We resected the tumor and reconstructed the IVC with a patch PTFE graft. The follow-up abdominal CT revealed no recurrence and obstruction of the IVC for 6 months after the operation.

Contrast media may cause tissue injury by extravasation during intravenous automated injection during CT examination. Here, we present a study in which contrast media extravasation was detected and localized in the neck and thorax by three-dimensional(3D) CT data reformation. The CT studies of the extavasation site were performed using a 3D software program with four different display techniques axial, multi planar reformation(MPR), maximum intensity projection(MIP), and volume rendering displays are currently available for reconstructing MDCT data. 3D image reconstructions provide accurate views of high-resolution imaging. This paper introduces extravasation with the MDCT and 3D reformation findings of contrast media extravasation in neck ant thorax. The followed injection of the external jugular vein into an existing intravenous catheter and a large volume of extravasation was demonstrated on by 3D MDCT.

Tuberculosis remains as a major public health problem worldwide. In addition to classic pulmonary tuberculosis, tuberculosis may sometimes present atypically. In the case of atypical tuberculosis, the unusual sites and properties that mimic other diseases can lead to a misdiagnosis and therapeutic delay. Abdominal and pharyngeal tuberculosis are uncommon extrapulmonary manifestations of tuberculosis. To the best of our knowledge, a combination of abdominal and pharyngeal tuberculosis with endobronchial tuberculosis has not been reported. We report a case of concurrent abdominal and pharyngeal tuberculosis in a patient with chronic endobronchial tuberculosis mimicking a metastatic malignancy on computed tomography and FDG-PET.
