title: Haemangiopericytoma of the middle ear: case report and literature review.
abstract: Haemangiopericytoma is an uncommon vascular tumour that rarely appears in the head and neck region. Such a tumour arising from the middle ear has not been reported since it was first described in 1942 by Stout and Murray. The present case therefore illustrates the first example of a primary middle ear haemangiopericytoma.
