Abstract

Takayasu arteritis (TAK) is a large-vessel vasculitis affecting the aorta and its main branches. Hemoptysis can be experienced as the respiratory manifestation, but origination from a bronchial artery is rare. Ulcerative colitis (UC) shares genetic similarities with TAK; HLA-B52*01 is associated with TAK and UC. We herein report a patient who presented with hemoptysis from the right bronchial artery and was diagnosed with TAK during the follow-up of UC. Transcatheter embolization was performed, and prednisolone and tocilizumab induced remission. Complication of TAK should be considered in the clinical course of HLA-B52-positive UC patients, and tocilizumab may be a treatment option.
