School ager with Factor 9 deficiency who has neck pain after being hit while playing football

MRI of subdural hematoma of the cervical spine.
Sagittal T1 (above leftmost), T2 (above left middle), STIR (above right middle) and gradient echo (above rightmost) MRI without contrast of the cervical spine shows a long linear fluid collection anterior to the cervical spinal cord from C1-C7 that is isointense on T1 weighted imaging, mixed isointense and hyperintense on T2 weighted imaging, and hyperintense on STIR and gradient echo imaging. On the axial T1 (below left) and T2 (below right) MRI the fluid collection is oval in shape and is seen anterior to the spinal cord and is causing compression on the spinal cord.

The diagnosis was cervical spinal subdural hematoma.
