abstract: An unusual tumour of the cerebellopontine angle.
  
  
  OBJECTIVE
  To report an extremely rare case of lipoma of the cerebellopontine angle (CPA).
  
  
  METHODS
  A 33-year-old woman presented with vertigo and tinnitus in the left ear. Her physical examination was unremarkable. Audiometric evaluation was normal in both ears. T1-weighted magnetic resonance imaging (MRI) without fat signal suppression revealed a hyperintense lesion of the left CPA. Based on the neuroimaging findings, the diagnosis was left CPA lipoma. The patient was managed conservatively. After 48 months, follow-up MRI revealed no further growth of the lesion and the patient was symptom free.
  
  
  CONCLUSIONS
  Lipomas of the CPA should be considered in the differential diagnosis of vertigo and tinnitus. Accurate diagnosis by MRI is critical.
