ABSTRACT

Diagnosis: Giant Cell Arteritis

History: 81 year old female history of vasculitis s/p long-term corticosteroid treatment and colon cancer s/p resection presents with increasing ESR/CRP on pre-operative evaluation for cataract surgery.

Findings: There is diffuse abnormal FDG uptake involving the aortic arch and its major branches. Additionally, there is low level FDG uptake involving the descending thoracic aorta, as well as the abdominal aorta. The diffuse abnormal uptake continues to involve the external iliac artery and into the superficial femoral arteries bilaterally.

Ddx: Giant Cell Arteritis Takayasu Arteritis-Imaging would be essentially the same as Giant Cell Arteritis, however can be generally distinguished based upon demographics. Giant cell arteritis occurs almost exclusively in older patients, while Takaysu arteritis occurs in patients aged 20-40. Atherosclerosis-PET would show mild heterogeneous enhancement with skipped areas, while more severe atherosclerosis could demonstrate ulcerated plaques. Vascular thrombosis-Would show increased FDG uptake in the lumen rather than the vessel wall.

Dxhow: Prior temporal artery biopsy

Exam: PE: Unremarkable Lab: ESR-25, CRP-1.40

No MeSH data available.
