A 50-year-old male patient complaining of neck pain with mJOA score = 17 (Mild grade). Conventional MRI: A Sagittal T2WI, B Sagittal T1WI, C, D Axial T2WI at CV5/6 disc level, Sagittal DTI: E ADC map, F FA grayscale map, G FA color map, H 3D tractography. A, B Sagittal T2WI (A) and Sagittal T1WI (B) showing straightening of cervical curve with uni-level bulky diffuse osteophytic disc complex bulge more inclined to left side at CV5/6 disc level, encroaching upon the sub arachnoid space narrowing of left neural exit foramen, the condition is augmented with mildly hypertrophied ligamentum flavum with mild 2ry canal stenosis at CV5/6. This disc level is seen indenting the related portion of the cervical cord (2nd degree), with no abnormal cord signal at T2WI and T1WI (Grade I). C, D axial T2WI at CV5/6 disc level showing bulky diffuse osteophytic disc complex bulge more inclined to left side that is seen indenting the subarachnoid space and compressing the related cord with no abnormal cord signal at T2WI and T1WI (Grade I). E Sagittal ADC map showing: ADC value at CV5/6 disc level (represented by arrow) = 1.2 × 10–3 mm2/s compared to 0.99 × 10–3 mm2/s at non-compressive site. F Sagittal FA grayscale map showing: low FA value at CV5/6 disc level = 0.57 (mild grade) compared to 0.7 at non-compressive site. G FA color map showing subtle indention of cord at FA color map with faint green color at site of cord myelopathy (CV5/6). H 3D tractography showing homogenous color of the cervical cord and intact fiber tracts (grade I)
