Klebsiella pneumoniae meningitis can cause spinal cord dysfunction in infants, a rare complication previously undocumented in those under one year old. This case highlights potential direct vascular causes in young children, leading to persistent neurological deficits.
Area of Science:
- Neurology
- Infectious Diseases
- Pediatrics
Background:
- Bacterial meningitis, particularly Klebsiella pneumoniae, can lead to rare neurological complications.
- Spinal cord dysfunction (myelopathy) is an uncommon sequela of bacterial meningitis.
Observation:
- An 8-month-old infant developed cervical transverse myelopathy during Klebsiella pneumoniae meningitis.
- This represents the youngest reported case of such a complication.
Findings:
- Unlike older children and adults who often present with thoracic or lumbar lesions, young children typically exhibit cervical cord lesions.
- In this case, spinal cord dysfunction occurred without cardiorespiratory arrest, suggesting direct vascular compromise and ischemia as the primary mechanism.
- Previous cases in young children (2-3 years) often involved cardiorespiratory arrest, indicating differing pathogenetic roles based on age.
Implications:
- This case expands the known age spectrum for myelopathy secondary to bacterial meningitis.
- It underscores the potential for direct vascular pathogenesis in young infants, distinct from mechanisms seen in older individuals.
- Persistent neurological deficits are a common outcome, emphasizing the severity of this complication.
Abstract:
Cervical transverse myelopathy developed in an 8-month-old girl during the early stages of Klebsiella pneumoniae meningitis. Spinal cord dysfunction is an uncommon complication of bacterial meningitis and has not been previously described in patients younger than 1 year old. A literature review of patients 2 years old or older with similar complications showed that young children have cervical cord lesions, whereas the majority of adolescents and adults have thoracic or lumbar lesions. In four of five previously reported cases of patients between 2 and 3 years old, a cardiorespiratory arrest probably played a critical role in the pathogenesis of cord dysfunction. The patient described herein, however, did not experience any cardiorespiratory insufficiency, and cord dysfunction was probably the direct result of local vascular changes and cord ischemia. On follow-up assessment, all patients had persistent neurologic deficits, regardless of age.
