RT Journal Article SR Electronic T1 Lyme neuroborreliosis presenting as spinal myoclonus JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e233162 DO 10.1136/bcr-2019-233162 VO 12 IS 12 A1 Xena Li A1 Aaron Kirschner A1 Mary Metrie A1 Mark Loeb YR 2019 UL http://casereports.bmj.com/content/12/12/e233162.abstract AB Early neurological Lyme disease (neuroborreliosis) typically presents with well-recognised neurological syndromes. Spinal myoclonus is however a rare manifestation of neuroborreliosis. We present the case of a man who developed spinal myoclonus 3 weeks after returning from the Czech Republic where he developed erythema migrans on his arm following multiple tick exposures. Spinal fluid analysis showed a pleocytosis and MRI showed enhancement at C5-C6. His serology was positive for IgM antibodies to Borrelia afzelli. He was successfully treated with ceftriaxone and doxycycline with improvement of his spinal myoclonus and radiculitis. We conclude that early Lyme neuroborreliosis may present with uncommon neurological manifestations and so a high degree of suspicion is needed.
