Infectious myelopathies, though rare, require prompt diagnosis for better outcomes. This review details various microorganisms causing spinal cord infections, emphasizing timely identification for effective treatment.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Spinal Cord Medicine

Background:

  • Infectious myelopathies are uncommon but necessitate rapid diagnosis for improved patient outcomes.
  • A diverse range of pathogens, including viruses (HIV, HTLV-I, herpesviruses, enteroviruses), bacteria (Treponema pallidum, Mycobacterium tuberculosis), fungi, and parasites, can cause spinal cord infections.
  • Vacuolar myelopathy in HIV-infected individuals and HTLV-I-associated myelopathy (tropical spastic paraparesis) are significant clinical entities.

Purpose of the Study:

  • To review infectious myelopathies based on the causative microorganisms.
  • To highlight the importance of considering infectious etiologies in the differential diagnosis of myelopathy.
  • To provide an overview of the clinical presentations associated with various infectious agents affecting the spinal cord.

Main Methods:

  • Literature review of infectious myelopathies.
  • Categorization of spinal cord infections by causative organism.
  • Discussion of clinical manifestations and diagnostic considerations.

Main Results:

  • Identified numerous pathogens responsible for infectious myelopathies, including HIV, HTLV-I, herpesviruses, enteroviruses, T. pallidum, M. tuberculosis, fungi, and parasites.
  • Highlighted vacuolar myelopathy as a common, often underrecognized, spinal cord disease in HIV.
  • Described HTLV-I-associated myelopathy's impact on pyramidal tracts and its characteristic symptoms.

Conclusions:

  • A broad spectrum of microorganisms can lead to myelopathy, presenting with varied clinical signs.
  • Physicians must maintain a high index of suspicion for infectious causes when evaluating patients with myelopathy.
  • Accurate and timely diagnosis of infectious myelopathies is crucial for effective management and improved neurological outcomes.
