Abstract:
The majority of epistaxes are anterior in nature, resolve with simple first aid measures and require no further follow-up. However, some cases pose more of a diagnostic challenge and prove resistant to standard investigation and treatment. We present a case of recurrent epistaxis, refractory to multiple treatment modalities and with CT imaging suggestive of a vascular aetiology which was ultimately disproved. The case highlights the shortcomings of CT imaging and importance of thorough examination technique. Nasal haemangiomas are a rare but recognised cause of epistaxis and should be considered in refractory cases.
