Disseminated intravascular coagulation complicating resection of a malignant meningioma

Abstract

A 70-year-old woman developed disseminated intravascular coagulation (DIC) during a craniotomy for a parasagittal anaplastic/malignant meningioma. This was successfully treated with rapid resection of the tumour and haematological replacement, but a poor neurological outcome resulted. The tumour was demonstrated to express tissue factor, an important causative factor in other tumour associated DIC and previously shown to be expressed by malignant meningiomas. A link between the two is suggested.
