Six cases of neuroinvasive Lyme disease

A cluster of six neuroinvasive Lyme disease cases is described by doctors from Mayo Clinic in the journal Open Forum Infectious Diseases. [1] Over a 3-week period between July and August of 2017, physicians from the Minnesota and Wisconsin campuses identified 6 patients with Lyme neuroborreliosis. Five of these cases presented with Bannwarth syndrome (BWS), an uncommon manifestation of neuroinvasive Lyme disease, which is typically seen in Europe, explains Shah and colleagues.

Bannwarth syndrome is characterized by painful radiculopathy, neuropathy, varying degrees of motor weakness and facial nerve palsy, and cerebrospinal fluid (CSF) lymphocytic pleocytosis. Five patients, Shah says, presented with peripheral nervous system involvement (primarily axonal in nature), which is consistent with BWS. We discuss three of the cases below.

61-year-old male

A 61-year-old male, who had a history of daily exposure to ticks, presented with “progressive back pain, upper torso and extremity paresthesias, right-sided facial droop, and blurry vision in the right eye,” writes Shah. Four weeks prior, he was treated for an EM rash with 5 days of doxycycline, given twice daily.

Test results indicated positive IgM and IgG antibodies to B. burgdorferi and he was diagnosed with LNB/BWS. According to Shah, “the patient demonstrated significant neurologic improvement following 4 weeks of intravenous (IV) ceftriaxone.”

62-year-old female

A 62-year-old female presented with subacute onset of lower extremity weakness. This progressed over a 3-week period to flaccid paralysis, writes Shah. The woman also complained of radiating low back and abdominal pain with associated numbness.

Tests confirmed the diagnosis of BWS and Lyme neuroborreliosis (LNB). “A magnetic resonance image (MRI) of her spine showed diffuse inflammation of the cauda equine,” says Shah. A pleocytosis by spinal tap and a positive real-time polymerase chain reaction (RT-PCR) assay confirmed the diagnosis.

The patient was diagnosed with LNB/BWS and discharged on a 4-week course of IV ceftriaxone. “The patient reported improved mobility,” says Shah, “though she still required extensive assistance 2 months post-treatment.”

29-year-old male

In June 2017, a 29-year-old male developed fever, myalgias, chills, headache and fatigue. He also reported a transient erythematous rash on his trunk. Two weeks later, he developed “right foot drop, Trendeleberg gait, lower extremity radiculopathy, and painful L5-S1 paresthesias,” explains Shah. And over the next 10 weeks, he lost 15 pounds.

After refusing a spinal tap, the man was diagnosed based on his clinical presentation and positive Lyme test results. The man was given IV ceftriaxone and two weeks later reported having no symptoms. It is not clear how often BWS occurs in actual practice with or without a confirmatory spinal tap.

All five patients presented with upper or lower extremity radiculopathy and/or paresthesias. There were, however, several other findings. “The more widespread peripheral neuropathy observed for the remaining 3 patients in this series is somewhat atypical,” writes Shah. “2 patients developed visual disturbances and nerve root enhancement in the cauda equine or lumbar spine, and 1 presented with Lyme disease–associated facial nerve palsy.”

The authors recommend, “The constellation of neurological symptoms, particularly when associated with a recent or suspected tick bite in an LD-endemic region, should prompt clinical evaluation for LNB and assessment for BWS as this syndrome may be more common than previously presumed in North America.”

    Quote- “… this syndrome may be more common than previously presumed in North America.” YA THINK? That’s why we call it Hold The Mayo! And they are just now figuring this out (or admitting it)? UGH!

    Yeah, I had same type symptoms, never recognized for what it was. It actually resolves and relapses. Pretty sure this is VERY common in Lyme.

    It bothers me they still.insist on spinal tap when the regular unintrusive blood smear does the same thing…

    Diagnoses around 1988 and treated with in three weeks of a tick bite. I thought I was cured after taking the RX. Forgot about it until two months ago while conversing with some they had told me they have Lyme Disease and I had mentioned that I “had” it. I was told to get a test from my PCP…tested positive 2018 and to Doxicycline for 30 days.

    Went for an eye exam and shared an temporary blindness in one eye for 2-3 mins. one summer day, passed out twice (hit my head on sink’s edge on my way down). Past vehicle accidents w/head injuries. Been experiencing migraine for five years straight which began after three car accidents (while sitting still). Past three months eye pain, headaches while asleep that awakes me.

    My eye doctor referred me to an opthamologist who then ref. me to a neurologist whom ref. me to a neuro-ophthalmology neuro-ophthalmologist for lumbar puncture to measure spinal fluids, conduct a brain scan for tumors, and to be treated for Psendopapilledema and papilledema to save me from blindness and brain damage.

    The right side of my right arm started swelling with pain daily for eight weeks and right hand swelling. Then my left leg began swelling.

    Do you think my issues favor Psendopapilledema or pappedilema symptoms? My neuro-ophthalmology appt. is four weeks away.

      I have often seen patients with a series of finding where a tick borne illness is a consideration. Your vision is a top priority and is being carefully evaluated. Your migraines, right arm swelling, left leg swelling, head trauma are additional concerns. There may be other issues you have not included in your notes. It would be reasonable to include an evaluation by a doctor familiar with tick borne pathogens.
