 The cervical spine is in normal alignment, with straightening of the normal cervical lordosis. There is moderate disc narrowing at C4-C5 and C5-C6. The vertebral body and disk heights are otherwise well-maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal signal.At C4-C5, there is a large left paramedian central disc extrusion which migrates cranially by 3 mm and caudally by 9 mm. The extruded disc material may be somewhat sequestered given its slightly differential signal. There is an underlying mild posterior osteophyte disk complex and bilateral uncovertebral hypertrophy resulting in overall severe central spinal canal stenosis at this level as well as moderate right and mild-moderate left foraminal narrowing. There is significant deformity of the cord with indentation focally in the left paracentral location.At C5-C6, there is a mild posterior osteophyte disk complex with slight left paracentral prominence. There is mild deformity of the ventral cord with overall moderate central spinal canal stenosis. Right greater than left uncovertebral hypertrophy contributes to overall mild-moderate right foraminal narrowing.There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the remainder of the cervical spine. There is trace left and moderate right mastoid air cell fluid signal. The right lobe of the thyroid gland is incidentally larger than the left with greater heterogeneity and there is a focal T2 hyperintensity and susceptibility suggested posteriorly, likely representing cystic change and calcification.
1.Significant cervical spondylotic changes especially at C4-C5 there is a large dental disc extrusion with possible sequestered disc material extending predominantly caudally resulting in severe central spinal canal stenosis and deformity of the cord without definite cord signal abnormality. Please correlate with physical exam and clinical symptoms.2.Asymmetric enlargement of the right lobe of thyroid gland with heterogeneous signal and focal areas of probable calcification and cystic change in the posterior aspect. Correlation with thyroid function tests is recommended and thyroid ultrasound may be obtained as clinically indicated.
