Brachial plexopathy as a complication of axillary artery aneurysm in a case of Takayasu arteritis

Anjum Siddiqui et al. BMJ Case Rep. .

Abstract

Takayasu arteritis is an inflammatory disease of unknown aetiology affecting large vessels. Medium vessel involvement is also well documented; however, neuropathy as a presenting manifestation is rare. In this case report, a young woman in her 20s presented with an 8-month history of intermittent claudication in the right upper limb progressing to rest pain with allodynia in C5-C8 distribution and painless right axillary mass. On examination, she had absent pulses in the right radial, brachial and subclavian artery with audible bruit in the right subclavian and abdominal aorta. CT angiogram showed features suggestive of Takayasu arteritis with a partially thrombosed aneurysm arising from the right axillary artery leading to compression of the right brachial plexus. This patient received treatment with methotrexate and oral corticosteroids. At 3 months follow-up, there was a reduction in the size of the aneurysm, resolution of compressive symptoms and normalisation of inflammatory markers.
