RESUMO
La enfermedad de Lyme es la infección transmitida por garrapatas más común en Norteamérica y Europa. Sin embargo, en América Latina se han reportado pocos datos. Borrelia burgdorferi es capaz de invadir el sistema nervioso central causando la neuroborreliosis de Lyme. Se comunica el caso de una mujer joven con encefalitis y síndrome cerebeloso, una presentación poco frecuente, que se manifestó con cefalea, marcha atáxica, nistagmo y ptosis palpebral. Se realizó el diagnóstico con serología positiva por Western blot para Borrelia burgdorferi en suero. Recibió tratamiento con mejoría clínica. El diagnóstico de neuroborreliosis es difícil, ya que no existen hallazgos neurológicos o de imagen específicos. Se recomienda tener un mayor nivel de vigilancia epidemiológica en Latinoamérica, así como los antecedentes recreativos o viajes, que deben incluirse en la historia clínica para mejorar la aproximación diagnóstica.
Lyme disease is the most common tick-borne disease in North America and Europe. However, in Latin America, few data have been reported. Borrelia burgdorferi is capable of invading the central nervous system causing Lyme neuroborreliosis. This is a case report of a female with encephalitis and cerebellar syndrome, a rare manifestation, presented with generalized headache ataxic gait, nystagmus and palpebral ptosis. Serologic diagnosis was made for Borrelia burgdorferi and treatment was initiated with clinical improvement. Neuroborreliosis is a very difficult diagnosis, since there are no neurologic or imaging findings specific. It is recommended to physicians to have an enhanced level of surveillance in Latin America, as well as recreational/travel history of the patient, which should be included in the clinical record to improve the diagnostic approach.

History A 24-year-old right-handed woman presented to a neuro-ophthalmology clinic in Massachusetts in the summer with acute binocular diplopia when looking down and to the left, which started about 1 month earlier. Her medical history was notable for Raynaud syndrome, recurrent streptococcal pharyngitis, and an allergy to amoxicillin. Three days prior to developing diplopia, she presented to an outside emergency department due to fever, chills, and back pain. She received ciprofloxacin for presumed urinary tract infection based on urinalysis, which demonstrated few bacteria and was negative for leukocyte esterase, nitrites, and white blood cells. She then presented again to an outside emergency department for diplopia evaluation. Initial MRI and MR angiography of the brain at that time did not demonstrate any relevant findings, and the patient was referred to our department for neuro-ophthalmic evaluation, where she was seen 4 weeks later. Neuro-ophthalmic examination revealed 20/20 visual acuity in both eyes, and a right hypertropia in left gaze, downgaze and right head tilt, with right eye excyclotorsion. There were no ocular signs of myasthenia gravis or thyroid eye disease, nor did the patient report ocular or systemic symptoms. She denied recent travel. High-spatial-resolution MRI of the brain and orbit were performed.
