Crohn's disease associated with Takayasu arteritis: Case report

Crohn's disease (CD) and Takayasu's arteritis (TA) are both chronic, granulomatous, autoimmune diseases, and their coexistence is extremely rare. This report describes the case of an adolescent diagnosed with CD who developed vasculitis affecting the aorta and major branches, leading to TA. The case highlights the clinical findings that led to the diagnosis and the therapy used. Additionally, it underscores the importance of considering vasculitis, most commonly TA, in patients with CD who present with thrombotic events and elevated inflammatory markers, even in the absence of gastrointestinal symptoms. Early diagnosis enables timely initiation of appropriate treatment to improve outcomes.
