The Lyme disease, which was first found in Lyme, USA, in 1975 is an in
fectious multi-system disorder whose agent, the Borrelia Burgdorferi,
was identified in 1983. Various disease manifestations have been repor
ted since them. We report a case of Lyme disease manifestation in the
muscle revealed by serious amyotrophy in the scapular muscles, in the
neck and in the trunk with scapula alata accompanied by noctural lumba
go which is resistant to non steroid antiinflammatory drugs. Electromy
ography showed patterns of the myogenic type in the serrate anterior a
nd infraspinous muscles on both sides and patterns of the neurogenic p
eripheral type in the lower extremities. The histological, immunohisto
chemical and electron-microscopal studies of the muscle biopsy have be
en without any pathological result. Creatine kinase and aldolase prove
d normal. Serological antibodies were not significantly increased. A p
ositive diagnosis was obtained by lumbar puncture which showed lymphoc
ytic meningitis, by demonstrating specific antibodies in the cerebrosp
inal fluid and by Western Blot antibodies analysis. Efficacy of the an
tibiotic therapy has resulted in a rapid regression of the symptoms, w
hich is a further confirmation of the previous diagnosis.
