Rarely, GCA presents with Horner\u2019s syndrome due to sympathetic neuron involvement from arterial inflammation. This case report discusses an 82\u2010year\u2010old female with hypertension, atrial fibrillation, and arthritis who presented with a 24\u2009h history of right eye ptosis, blurred vision, dizziness, and aching eye pain. She had a mild headache and tenderness over the right temporomandibular joint but no temporal artery tenderness. Examination revealed right eye ptosis and miosis, indicative of Horner\u2019s syndrome, with no other neurological deficits. Lab results showed elevated ESR (68\u2009mm\/h) and CRP (16\u2009mg\/L). MRI with contrast revealed mild to moderate stenosis and enhancement in bilateral MCAs and basilar artery with inflammation in the right distal extracranial ICA, suggesting an inflammatory process. The patient was started on prednisone 40\u2009mg daily. A temporal artery biopsy confirmed GCA with characteristic histopathological findings. Her prednisone dosage was increased to 60\u2009mg\/day, and she was started on tocilizumab. This case underscores the need to consider GCA in patients with Horner\u2019s syndrome and the importance of vessel wall imaging, as early corticosteroid treatment can prevent complications like vision loss and stroke.<\/jats:p>","DOI":"10.1155\/crnm\/2503963","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T02:50:26Z","timestamp":1733799026000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unveiling the Uncommon: A Case Report of Horner\u2019s Syndrome as a Rare Glimpse Into Giant Cell Arteritis"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9788-3596","authenticated-orcid":false,"given":"Emily","family":"Barr","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justine","family":"Levesque","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2738-5922","authenticated-orcid":false,"given":"John","family":"Badir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randall","family":"Dunston","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamra","family":"Ranasinghe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,9]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard-2022-223480"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40744-017-0052-8"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-016-1127-3"},{"key":"e_1_2_10_4_2","volume-title":"The Systemic Manifestations of Temporal Arteritis","author":"Healey L.
