Clinical history: ? spinal stenosis cervical spine, left thumb numbness/pain
PROTOCOL: Multiplanar multisequence MR images of cervical spine without contrast incluing survey images,
sagittal T2, sagittal T1, axial 3D BFFE, axial T2, & sagittaal R2 fat-sat.
FINDINGS: The craniocervical junction is unremarkable without evidence of Chiaria malformation.
The C1-2 level, C2-3 level & C3-4 level are unremarkable. No evidence of central canal or neural foraminal stenosis at these levels.
At C4-5, there is a moderate sized central osteochondral bar with a predominance within the left lateral recess & left neural foramen. This causes moderate to severe canal stenosis at this level. This also impinges the exiting left-sided vental nerve root at this level.
OPINION: Multilevel degenerative changes most marked at C5-6 where there is impingement within the central canal of moderate to severe degree and impingement of the exiting ventral left-sided nerve root at this level. Clinical correlation with the patient's level and laterallyh of symptoms, is suggested.
In layperson's terms, what does this all mean?
