Endonasal resection of a sinonasal hemangiopericytoma

The presented case shows a long-term benign course of recurrent sinonasal HP following endonasal resection. After more invasive approaches, such as lateral rhinotomy, local recurrence has been reported to appear within comparable periods of time. If the tumour is of limited extension, without infiltration of neighbouring structures, it can be removed via an endonasal approach.
