Insights

A pediatric case of transverse myelitis and encephalitis linked to ECHO virus type 11 showed spinal cord lesions on MRI. The patient achieved a full recovery within weeks, with MRI lesions resolving completely over months.

Area of Science:

  • Neurology
  • Pediatrics
  • Infectious Diseases

Background:

  • Transverse myelitis is an inflammatory condition affecting the spinal cord.
  • Encephalitis involves inflammation of the brain.
  • Viral infections are a known cause of both myelitis and encephalitis.

Observation:

  • A 14-year-old boy presented with symptoms of incomplete transverse myelitis and mild encephalitis.
  • Magnetic resonance imaging (MRI) revealed T2-weighted hyperintensities in the central spinal cord (C1-T5) with cervical cord expansion.
  • Pharyngeal exudate cultures identified ECHO virus type 11.

Findings:

  • ECHO virus type 11 infection was associated with transverse myelitis and encephalitis in a pediatric patient.
  • The patient experienced a rapid and complete clinical recovery within weeks.
  • Follow-up MRI demonstrated complete resolution of the spinal cord lesions within months.

Implications:

  • This case highlights ECHO virus type 11 as a potential pathogen causing myelitis and encephalitis in children.
  • Early diagnosis and supportive care can lead to favorable outcomes in viral-induced myelitis.
  • Further research into the neurotropic effects of enteroviruses is warranted.

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
