A 36-year-old lady presented with insidious onset, gradually progressive neuropathic pain, sensory loss, and weakness of the right upper limb. Her brachial, ulnar, and radial pulses were not palpable on the right side and feeble on the left. She had an irregular, ill-localized 8 cm × 6 cm pulsatile swelling in the right supraclavicular region with thrill on palpation and bruit on auscultation. Motor system examination revealed grade 4 power with wasting of thenar muscles. Nerve conduction studies were suggestive of pan-brachial plexus involvement. Computed tomography angiogram images revealed thickening of the aortic arch, irregular narrowing of the descending aorta, and aneurysm of the right subclavian artery. She was diagnosed to be suffering from right brachial plexopathy due to compression by aneurysm of the right subclavian artery secondary to Takayasu's arteritis. The case is rare as no such presentation has been reported earlier.
