Uncommon Magnetic Resonance Imaging Observation of Lumbar Subdural Hematoma with Cranial Origin

Abstract

A patient with a history of pain, paresthesias, and weakness in both legs is reported. Magnetic resonance imaging (MRI) of the lumbar spine demonstrated subacute subdural hematoma. Brain MRI obtained 1 day later because of progressive headache showed hemorrhagic cortical metastasis and extensive subdural hematoma. It is hypothesized that the lumbar hematoma originated from the intracranial bleeding, which was substantiated by the observation of a thin hemorrhagic collection connecting cranial and lumbar hematomas on MRI. Cranial origin should be included in the differential diagnosis of spontaneous spinal subdural hematomas.
