Fever and fatigue with signs of neurological deficits and pulmonary hypertension point to which vasculitis?

• A. Giant cell arteritis
• B. Polyarteritis nodosa
• C. Wegener's granulomatosis
• D. Takayasu arteritis

Answer: (D)

This question hinges on recognizing a large-vessel vasculitis that targets the aorta and its major branches and can produce both systemic symptoms and signs from cerebral and pulmonary involvement. Takayasu arteritis typically affects young individuals and presents with fever and fatigue as part of its inflammatory process. Its vessel involvement can involve the carotid and other arteries supplying the brain, leading to neurological symptoms such as dizziness, syncope, or even stroke-like deficits. Pulmonary hypertension can occur when the disease affects the pulmonary arteries or causes secondary changes in the pulmonary circulation. The combination of constitutional symptoms with neurological signs and potential pulmonary vascular involvement points to Takayasu arteritis. In contrast, giant cell arteritis usually occurs in older patients and presents with headaches, scalp tenderness, jaw claudication, and vision problems rather than pulmonary hypertension. Polyarteritis nodosa involves medium-sized arteries and often presents with abdominal pain, renal hypertension, skin findings, and peripheral neuropathy, but the lungs are typically spared. Wegener’s granulomatosis (granulomatosis with polyangiitis) involves the respiratory tract and kidneys and can cause neuropathies, but pulmonary hypertension is not a hallmark feature.
