Trigger Point Injection as a Rare Cause of Ischemic Stroke: A Case Report.

INTRODUCTION: Myofascial pain syndrome is a painful local or regional disease caused by myofascial trigger points. Trigger point injection (TPI) is a frequently used method for the treatment of myofascial pain. Major complications associated with TPI have rarely been reported in the literature. CASE REPORT: A 24-year-old woman, without medical history of any disease, was diagnosed with myofascial syndrome based on the presence of long-standing neck and right arm pain, and TPI with lidocaine was applied to the right trapezius region. During the procedure, blurred vision and loss of strength in the left arm occurred. Magnetic resonance and computed tomography imaging of the brain revealed findings that were consistent with an ischemic stroke in the right capsular interna and right occipital region. CONCLUSION: The reported patient is the first in the literature who suffered from ischemic stroke after TPI. The use of ultrasound for injections into the neck muscles could avoid serious complications.

Senile-Onset Subacute Sclerosing Panencephalitis, Presenting With Peculiar Findings.

Subacute sclerosing panencephalitis (SSPE) is a well-known childhood disease; however, the adult onset of SSPE cases are also widely recognized where the oldest case reported is 52 years old. We report a 61-year-old woman patient presenting with atypical clinical and EEG features, diagnosed with SSPE. Measles and SSPE have decreased dramatically owing to worldwide immunization programs; however, there are still reasons to consider SSPE in differential diagnosis even in patients presenting with atypical clinical findings and older ages. First, there is a generation who missed the immunization era, constituting a latent disease pool. Second, antivaccination movements have led to a decline in MMR (measles, mumps, rubella) vaccination worldwide, leading to measles outbreaks and potential future SSPE cases. Third, most of the vaccination programs start measles immunization at the age of 12 months, leading to a shift in the incidence below the age of 1 year, when the risk of developing SSPE in adult life is higher. Finally, disruption in vaccination programs, in which fast disease transmission due to close contact living, unhygienic conditions of refugee camps, and limited access to health care in displaced populations have also led to measles outbreaks. In conclusion, we believe that neurologists for adults should consider SSPE in differential diagnosis, even in older patients with atypical presentations.
