43 y/o woman was admitted whit sudden unset of nausea and Fatigue. She has history of Numbness in Lt upper limbs
Widespread periventricular , subcortical & white matter regions of hyperintensity on T2 are present including some which demonstrate enhancement. Single T2 weighted axial image through the cervical cord demonstrates a well defined high signal region affecting the Lt dorsal column According to Polman criteria DIS & DIT are present.
Discussion (Related Text)
An unpredictable disease of the central nervous system, multiple sclerosis (MS) can range from relatively benign to somewhat disabling to devastating, as communication between the brain and other parts of the body is disrupted. Many investigators believe MS to be an autoimmune disease - one in which the body, through its immune system, launches a defensive attack against its own tissues. multiple sclerosis requires establishing disease disseminated in both space and time.
Dissemination in space
Dissemination in space requires ≥1 T2 bright lesions in two or more of the following locations 1:
• spinal cord
o if a patient has a brainstem/spinal cord syndrome, the symptomatic lesion(s) are excluded from the criteria, not contributing to the lesion count
Dissemination in time
Dissemination in time can be established in one of two ways:
1. a new lesion when compared to a previous scan (irrespective of timing)
o T2 bright lesion and/or gadolinium enhancing
2. presence of asymptomatic enhancing lesion and a non-enhancing T2 bright lesion on any one scan.
