title: Haemangiopericytoma of the middle ear with benign histological features.
abstract: Haemangiopericytoma is a rare vascular tumour, particularly in the head and neck region. We described the first case of haemangiopericytoma arising from the middle ear in 1995. The present case is the second example of a primary middle-ear haemangiopericytoma with benign histological features. Clinical photography, computed tomography (CT) and magnetic resonance imaging (MRI) scans and histological photographs depict the findings.
