A patient with Takayasu arteritis presenting with malignant hypertension: a case report.

BACKGROUND

Takayasu arteritis (TA) is a rare large-vessel vasculitis primarily affecting the aorta and its proximal branches. The manifestation of TA is variable, ranging from asymptomatic cases to severe organ dysfunction secondary to vascular damage, which often delays diagnosis.

CASE SUMMARY

Here, we present a 37-year-old male patient suffering from visual impairment and malignant hypertension. Emergency fundoscopy showed large left subretinal bleeding and bilateral signs of hypertensive retinopathy. Echocardiographic and magnetic resonance imaging showed mildly reduced left ventricular ejection fraction and signs of hypertensive cardiomyopathy. Evaluation for secondary causes of arterial hypertension did not reveal an underlying disease, and the patient was discharged with optimal medical therapy. He was re-admitted after 11 days with fever of unknown origin, fatigue, and elevated inflammatory markers. The diagnosis of TA was finally established using F-fluorodeoxyglucose positron emission computed tomography scan and sonography of carotid and subclavian arteries. Anti-inflammatory combination therapy for active, severe TA with ophthalmologic involvement was initiated using high-dose glucocorticoids and the tumour necrosis factor alpha inhibitor adalimumab to minimize drug-related risks. The patient was scheduled for multidisciplinary follow-up appointments, including specialist consultation in rheumatology, angiology, cardiology, diabetology, and ophthalmology.

DISCUSSION

This case highlights the diversity of initial symptoms, the challenges of TA diagnosis, and the importance of comprehensive evaluation for rare secondary causes of arterial hypertension. Individualized acute and long-term care necessitates multidisciplinary management of immunosuppressive therapy, secondary organ involvement, and concomitant diseases.
