Intravascular Lipoma of the Right Subclavian Vein / 결핵및호흡기질환

Lipomas are common soft tissue tumors that are located in the body tissues containing adipose tissues. However, lipomas arising from the walls of a vein are very rare. Intravascular lipomas have been described most commonly in association with the inferior vena cava. Intravascualar lipomas involving the subclavian vein are rare. We are reporting a case of an asymptomatic lipoma of the right subclavian vein, growing into the right brachiocephalic vein.

A Case of Empyema Caused by Streptococcus Constellatus / 결핵및호흡기질환

Streptococcus constellatus (S. constellatus) is a commensal microorganism belonging to the "Streptococcus milleri" group, but may cause infections in different locations in immunocompromised patients. The infection of S. constellatus has high mortality and morbidity due to its tendency to cause abscesses in infected patients, which require immediate surgical drainage for effective treatment. We report on a 72-year-old woman with end stage renal disease, who suffered from dyspnea and general weakness that had developed over 7 days. Chest CT showed loculated pleural effusion. S. constellatus was cultured from exudative pleural effusions and confirmed by an analysis of 16S rRNA sequence. The patient was treated with drainage of pleural effusion and piperacillin/tazobactam for 5 weeks.
