Intralabyrinthine schwannoma, a rare tumor, can cause hearing loss and dysequilibrium. This case highlights successful pre-operative diagnosis using MRI, enabling timely surgical intervention for this inner ear tumor.

Area of Science:

  • Neuro-oncology
  • Otolaryngology
  • Neurosurgery

Background:

  • Intralabyrinthine schwannoma is an exceptionally rare tumor originating within the inner ear.
  • Historically, diagnosis often occurred post-operatively or via post-mortem examination.
  • Early detection of inner ear tumors remains a diagnostic challenge.

Observation:

  • A patient presented with chronic dysequilibrium and progressive hearing loss.
  • Symptoms were attributed to a suspected intralabyrinthine schwannoma.
  • Magnetic resonance imaging (MRI) with gadolinium contrast was utilized for diagnostic evaluation.

Findings:

  • MRI revealed an intralabyrinthine schwannoma.
  • Surgical excision of the tumor was performed.
  • Pathological examination confirmed the diagnosis of schwannoma.

Implications:

  • This case underscores the utility of advanced imaging in diagnosing rare inner ear tumors.
  • Pre-operative diagnosis allows for planned surgical management, potentially improving outcomes.
  • Highlights the importance of considering intralabyrinthine schwannoma in patients with unexplained vestibular and auditory symptoms.
