Introduction:
Acute myelitis accounts for 4 to 5 percent of all cases of neuroborreliosis. In the literature, simultaneous spinal MRI and cerebrospinal fluid (CSF) investigations are presented for only 8 cases. We describe here 3 cases of acute Lyme myelitis.
Method:
In a cohort of 45 patients with neuroborreliosis, diagnosed between January 1998 and January 2005, 3 had acute myelitis. Clinical, biological and radiological data were studied.
Case Reports:
The three patients had motor, sensorial and sphincter involvement. Extra-spinal involvement, such as fever and headache for one, facial nerve palsy for the second and subarachnoid hemorrhage for the third, was also noted. Pleocytosis varied from 10 to 520 white cells per mm3. Lyme serology was positive in CSF for all. Intrathecal anti-Borrelia antibody index was positive or intermediate for all three patients. Spinal cord MRI revealed a large hyperintense zone involving more than 3 vertebral segments. Myelitis was central, posterior or transverse in the axial plane. The clinical course was favorable after a three-week course of appropriate antibiotics.
Conclusion:
These 3 cases and the others from the literature show the diversity of the clinical and radiological features of acute myelitis: transverse, central or posterior myelitis. Thus, Lyme serology in CSF in indicated for patients presenting acute myelitis, particularly in endemic areas.
Insights
Acute Lyme myelitis, a rare form of neuroborreliosis, presents diverse clinical and imaging features. Early Lyme serology in cerebrospinal fluid (CSF) is crucial for diagnosing acute myelitis, especially in endemic regions.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Acute myelitis constitutes 4-5% of neuroborreliosis cases.
- Simultaneous spinal MRI and CSF investigations are rarely reported.
- This study details three cases of acute Lyme myelitis.
Observation:
- Patients presented with motor, sensory, and sphincter dysfunction.
- Extra-spinal symptoms included fever, headache, facial nerve palsy, and subarachnoid hemorrhage.
- Spinal cord MRI showed extensive lesions (>3 vertebral segments).
Findings:
- CSF analysis revealed pleocytosis and positive Lyme serology in all patients.
- Intrathecal anti-Borrelia antibody index was positive or intermediate.
- Myelitis patterns varied: central, posterior, or transverse.
Implications:
- Lyme myelitis exhibits diverse clinical and radiological manifestations.
- CSF Lyme serology is essential for diagnosing acute myelitis in endemic areas.
- Prompt antibiotic treatment led to favorable clinical outcomes.
