Lyme disease is a zoonosis caused by spirochetes of the genus Borrelia, presenting with a broad spectrum of clinical manifestations. This heterogeneity may hinder diagnosis, particularly in regions with low prevalence.
We present the case of a 65-year-old woman who attended the emergency department with a 24-hour history of diplopia upon awakening, without other neurological focal signs. Neuroborreliosis was diagnosed after identifying a history of travel to an endemic area and compatible cutaneous manifestations. Clinical progression, together with serological confirmation, enabled early diagnosis and initiation of appropriate antibiotic therapy, resulting in complete resolution of symptoms.
This case highlights the importance of including Lyme disease in the differential diagnosis of patients with any neurological focal signs and a history of travel to endemic regions, even in the absence of recalled tick bites or classical manifestations. Early detection and timely treatment are crucial to prevent chronic and disabling complications.
