case_images: a, b Axial T1- and T2-weighted MR images at the time of presentation 1 week after the onset of symptoms show subarachnoid hemorrhage of high signal intensity at the L1 level, in the anterior (arrow) and lateral (arrowhead) subarachnoid space

case_images: The subarachnoid process was of increased signal intensity relative to the spinal cord on both T1- and T2-weighted images; which was suggestive of subacute hemorrhage (Fig. 1).
case_images: a, b Corresponding sagittal T1- and T2-weighted MR images show increased signal in CSF extending from L1 through L5, consistent with subarachnoid hemorrhage (arrowheads). An ovoid area of high signal intensity on T1-weighted images (a) located at the T11-T12 level represents concomitant subdural hematoma (arrow). The hematoma (arrow), which is less well depicted on T2-weighted images (b) contains a characteristic focal region of low signal intensity (thin arrow) indicating the presence of deoxyhemoglobin

case_images: T2-weighted images, the lesion showed heterogeneously increased signal intensity with a focus of low signal intensity compatible with subacute hematoma containing deoxyhemoglobin (Fig. 2). The subdural hematoma was compressing the adjacent spinal cord without obvious signal changes within the cord.
case_images: Evolutionary MR-imaging changes of subdural hematoma show that as the hematoma aged, the signal intensity increased. a, b Follow-up axial T1- (a) and T2-weighted (b) MR images obtained 26 days after onset of symptoms show subdural hematoma (arrow) of increased signal intensity on both sequences. c, d Repeat axial T1- (c) and T2-weighted (d) MR images at a 5-month follow-up show resolution of subdural hematoma

case_images: Repeat MR-imaging studies revealed gradual resolution of both hemorrhages (Fig. 3).
