UNLABELLED: An unusual tumour of the cerebellopontine angle. OBJECTIVE: To report an extremely rare case of lipoma of the cerebellopontine angle (CPA). CASE REPORT: 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. CONCLUSION: Lipomas of the CPA should be considered in the differential diagnosis of vertigo and tinnitus. Accurate diagnosis by MRI is critical.

Isotretinoin, a medication for acne, has been reported to cause a variety of side effects on the musculoskeletal system. We present a case of sacroiliitis (a relatively uncommon feature) and sensorimotor demyelinating polyneuropathy, which has been reported previously in only a few cases during isotretinoin therapy. Clinical symptoms were improved after the withdrawal of isotretinoin and the follow-up electrophysiological study performed 2 years after the initial diagnosis of polyneuropathy showed mild improvement. Dermatologists are advised to be alert to symptoms of polyneuropathy and sacroiliitis during treatment with isotretinoin.
