Sudden onset of symptoms in concurrent Takayasu arteritis and Ulcerative colitis: A case report with neurological complications

Key Clinical MessageThe rare co-occurrence of takayasu arteritis (TAK) and ulcerative colitis (UC), presenting with asymptomatic onset and neurological complications, highlights the importance of an integrated diagnostic approach for overlapping autoimmune conditions.AbstractWe present a rare case of a 44-year-old female diagnosed with both UC and TAK, characterized by an unusual acute asymptomatic onset accompanied by neurological manifestations. The patient exhibited symptoms of acute ischemic stroke along with vascular abnormalities, as well as colon inflammation associated with UC. The patient's asymptomatic presentation at the onset differs from previously reported cases. The presence of additional complications, such as hepatocellular adenoma and primary sclerosing cholangitis, further complicated the diagnostic challenges. The patient's treatment involved a combination of methylprednisolone, azathioprine, and prednisolone leading to improved clinical outcomes. This case emphasizes the complexity involved in diagnosing overlapping conditions and highlights the significance of TAK in presenting atypical manifestations in relation to UC. Furthermore, this case contributes to the limited literature, underscoring the need for early detection and comprehensive treatment approaches.
