RESUMO
Purpose: Abducens schwannomas are rare tumors that are not known to present with acute haemorrhage. We present a case of a 59 year-old female on warfarin who presented acutely with a sudden onset headache, nausea and photophobia. Neuroimaging revealed an acute haemorrhage into a lesion that entered Dorello's canal and was consistent with an abducens nerve schwannoma.Materials and methods: The patient's case notes, imaging, histology and operative recording were reviewed retrospectively to compile this case report.Results: The tumor was resected via a retro-mastoid approach with sacrifice of the abducens nerve. Removal of the haematoma intra-operatively provided more space in the surgical corridor to facilitate resection. Final histological examination confirmed the diagnosis of schwannoma and the patient made a good post-operative recovery.Conclusion: We conclude that accurate pre-operative radiological diagnosis can facilitate surgical planning and removal of haematoma at an early stage during the operation can create space and facilitate resection. Furthermore, abducens schwannoma should be considered in the differential diagnosis of any heamorrhagic cerebello-pontine angle lesion.
