Female, 51 years old, with left arm pain and possible C6-7 cyst or lesion seen on outside hospital exam. A mild reversal of the normal cervical lordosis is seen. Vertebral body heights are preserved. Mild degenerative endplate irregularity is seen at several levels, most notably C5-6. No worrisome marrow replacement or marrow edema is detected.The visualized spinal cord shows normal morphology and signal characteristics except as discussed below.An oval T2 hyperintense structure measuring up to 5 mm in length is evident within the left C6-7 neural foramen, corresponding to a similar-appearing lesion noted on the prior outside examination. This lesion shows no internal enhancement. A similar-appearing but smaller structure is evident within the left C7-T1 neural foramen.No pathologic marrow space or intraspinal enhancement is seen.C2-3: Unremarkable. C3-4: Left facet hypertrophy. Mild posterior disc-osteophyte complex formation. Mild effacement of the ventral thecal sac. Mild left foraminal narrowing. C4-5: Mild posterior disc-osteophyte complex formation. Mild effacement of the ventral thecal sac with slight flattening of the ventral cord but no cord signal abnormality. Mild to moderate bilateral foraminal narrowing. C5-6: Left facet hypertrophy. Posterior disc-osteophyte complex formation. Moderate ventral dural sac effacement with flattening of the ventral cord but no significant cord signal abnormality. The overall spinal canal is moderately narrowed. Severe right and moderate left foraminal narrowing. C6-7: Facet hypertrophy. Posterior disc-osteophyte complex formation. Mild ventral thecal sac effacement without significant canal stenosis. Mild foraminal narrowing.C7-T1: Unremarkable.
1.A subcentimeter structure is identified within the left C6-7 neural foramen showing imaging characteristics most compatible with a perineural root sleeve cyst. There is also very likely an additional smaller root sleeve cyst within the left C7-T1 neural foramen.2.Mild to moderate cervical degenerative findings most significantly affecting the C5-6 level where there is a moderate spinal canal narrowing and severe right/moderate left foraminal narrowing.
