9. KEY ELEMENTS
Intramedullary T2 hyperintense signal in the setting of symptoms of
acute cord compression is an urgent finding and probably indicates
acute cord edema and ischemia

10. KEY ELEMENTS
High signal intensity on T2

11. CASE 1
Tingling and numbness in both hands and right leg. Lhermitte's
phenomenon with neck extension. 4/5 weakness in finger abduction
and reduced pinprick sensation in medial forearm (right more than
left). Upgoing right plantar response.
This patient had predominantly sensory symptoms with mild motor
deficits and was referred to neurosurgical services for their opinion
on decompression.
