Hypophonia, or reduced speech volume, can occur after acute stroke. This case suggests isolated lacunar infarcts in the corona radiata may cause hypophonia.

Area of Science:

  • Neurology
  • Stroke Medicine
  • Neuroimaging

Background:

  • Hypophonia, characterized by reduced speech volume, is an infrequent clinical sign in acute stroke.
  • It is predominantly associated with multiple deep cerebral infarcts.

Observation:

  • An 82-year-old hypertensive female presented with acute right-sided hemiparesis and significant hypophonia.
  • Magnetic resonance imaging revealed a small, acute lacunar infarct in the left corona radiata, with no other significant findings.

Findings:

  • The case highlights a potential association between isolated lacunar infarcts in the corona radiata and the development of hypophonia.
  • This contrasts with the more common etiology of multiple deep infarcts.

Implications:

  • This finding suggests that specific, localized lesions in the corona radiata may be sufficient to cause hypophonia.
  • Further research is warranted to elucidate the precise neuroanatomic correlates and prognostic implications of stroke-induced hypophonia.
