Tingling, Numbness in Lower Limbs: A Case Study

Sagittal T1WI showed diffuse abnormal isointense lesions occupying more than two-thirds of the spinal cord at mid-dorsal cord region at D4-5 and D7-8 levels associated with minimal dilatation of central canal

Sagittal and axial T2WI revealed hyperintensity of the lesions.

Sagittal and axial T2WI revealed hyperintensity of the lesions.

Sagittal DWI showed slight hyperintensity of the lesions denoting unrestricted diffusion.

ADC map showed low signal intensity of the lesions denoting unrestricted diffusion.

ADC map showed low signal intensity of the lesions denoting unrestricted diffusion (Figure 5). ADC value was measured at (b=1000) 1.1×10–3 mm2/s.

What do these images suggest is the cause of bilateral lower limb symptoms of 4 months’ duration?

Diagnosis: Transverse myelitis
