Infrequently, intracranial neoplasms metastasize to extracranial sites. In 1963, Glasauer and Yuan reviewed the 88 reported cases of metastatic intracranial tumours of which approximately two-fifths were meningiomas. This report concerns an angioblastic meningioma with a large hepatic metastasis. Cushing's original classification of angioblastic meningiomas and the differential diagnosis betwee...

Introduction The secretion of a hormone with insulin-like activity by hepatic metastases is an uncommon complication of non-pancreatic malignant tumours (Laurent, Debry and Floquet, 1971). A case is now reported of retroperitoneal malignant haemangiopericytoma with recurrent hypoglycaemic attacks resulting from hepatic metastases. Following hepatic angiography, hypoglycaemia has been effectivel...

A case of haemangiopericytic meningioma of the sacral canal in a 25 year old man, an uncommon tumour at a rare site, is described. The tumour was malignant and largely undifferentiated although there was light and electron microscopic evidence of dual differentiation in areas towards haemangiopericytoma and meningioma. The patient, with cauda equina syndrome, was treated by partial resection an...

Haemangiopericytoma is a rare, highly vascular, slow-growing tumour which has both malignant and benign varieties. We report a case of a 63-year-old man in whom it was treated by initial radiotherapy followed by complete surgical excision. The preoperative radiotherapy markedly reduced the vascularity of the tumour. A brief review of the pathology and nature of tumour is provided. q 1999 Elsevi...

Solitary fibrous tumour (SFT) is a rare, spindle-cell, mesenchymal neoplasm with haemangiopericytoma-like branching vascular pattern. The tumour has been reported in various locations but the oral cavity is a distinctly uncommon region. We describe a case of solitary fibrous tumour (SFT) in the tongue of a 15-year-old girl. Microscopically it had features characteristic for SFT and a common imm...
