A woman experienced sudden unilateral tinnitus due to a cavernous angioma hemorrhage near her auditory cortex. This suggests central tinnitus may arise from abnormal neural network activation in auditory perception.

Area of Science:

  • Neurology
  • Neuroscience
  • Otolaryngology

Background:

  • Tinnitus, a perception of sound without an external source, can have various etiologies.
  • Central tinnitus theories propose dysfunction within auditory processing pathways in the brain.

Observation:

  • A 25-year-old woman presented with acute onset of unilateral tinnitus.
  • Imaging revealed a small cavernous angioma adjacent to the contralateral primary auditory cortex.

Findings:

  • The patient's tinnitus was attributed to acute hemorrhage of the cavernous angioma.
  • The lesion's proximity to the primary auditory cortex suggests a direct link to auditory processing.

Implications:

  • This case supports the hypothesis that central tinnitus results from pathological activation of neural networks.
