RESUMEN
This case report describes a complicated case of giant cell arteritis (GCA) with tongue necrosis and bilateral central retinal artery occlusion (CRAO). An 81-year-old male patient with a history of recent retinal artery occlusion, ischemic stroke, and hypertensive emergency was evaluated. Clinical examination, including a visual acuity assessment, fundus evaluation, and oral examination, was performed. Laboratory investigations, such as erythrocyte sedimentation rate (ESR), were conducted. A temporal artery biopsy was performed to confirm the diagnosis of GCA. The patient presented with sudden vision loss in the left eye following a prior episode of retinal artery occlusion in the right eye. Ophthalmoscopic examination revealed CRAO in the left eye. Additionally, tongue necrosis, a rare manifestation of GCA, was observed. The ESR was significantly elevated. A temporal artery biopsy supported the diagnosis of GCA. The patient was promptly referred for immunologist consultation and initiated on intravenous methylprednisolone therapy. This case highlights the diverse and potentially devastating nature of GCA, involving ocular and systemic manifestations. Bilateral CRAO and tongue necrosis are rare but significant complications of GCA. Prompt diagnosis and early initiation of corticosteroid therapy are crucial to prevent irreversible visual loss and further complications. A multidisciplinary approach involving ophthalmologists and other specialists is essential for the comprehensive management of GCA.
