Acute spontaneous spinal subdural haematoma: MRI features

We present MRI findings in three patients with acute spontaneous subdural h aematomas of the spine. Acute haematomas (1-3 days) were isointense or gave slightly high signal on T1- and heterogeneous signal on T2-weighted images . MRI precisely defined the level and extent of the haematoma preoperativel y. The MRI was prospectively correctly interpreted as acute subdural haemat omas in all patients. As a specific, noninvasive modality, MRI is the prefe rred imaging technique in this rare clinical entity.
