Primary lateral sclerosis (PLS) is a rare neurodegenerative disease affecting motor pathways. This case study details a 43-year-old woman with PLS, highlighting frontal motor area hypometabolism.

Area of Science:

  • Neurology
  • Neurodegenerative Diseases
  • Clinical Case Study

Background:

  • Primary lateral sclerosis (PLS) is a rare, progressive motor neuron disease.
  • Characterized by corticospinal tract degeneration, leading to spasticity and weakness.
  • Typically spares sensory and autonomic functions, with late-onset cognitive changes.

Observation:

  • A 43-year-old woman presented with symptoms consistent with PLS.
  • Clinical follow-up spanned 3 years with comprehensive investigations.
  • A SPECT study revealed bilateral hypometabolism in the frontal motor areas.

Findings:

  • The case illustrates the progressive nature of PLS affecting motor pathways.
  • SPECT imaging identified specific patterns of reduced brain activity.

  • Differential diagnosis from other neurological disorders was considered.

    • Implications:

    • This case contributes to understanding the clinical presentation of PLS.
    • Highlights the utility of neuroimaging in diagnosing rare neurological conditions.
    • Emphasizes the importance of distinguishing PLS from more common motor neuron diseases.
