 There is stable reversal of the normal cervical lordosis. There is mild disk narrowing at C5-6. The vertebral body and disk heights are otherwise well-maintained. There is mild multilevel disc desiccation. No worrisome focal marrow signal abnormality is appreciated. There is no pathological cord enhancement.There is a small left intradural extramedullary mass likely meningioma at the C1 level (image 33, series 709) measuring 9 x 5 mm, unchanged from prior exam. At the right C2-C3 neural foramen, there is an enhancing mass measuring approximately 17 x 8 mm, also stable (image 26, series 2001). Along the left C3-C4 neural foramen, there is an enhancing dumbbell-shaped mass approximately measuring 25 x 10 mm, previously 26 x 10 mm. The medial lobule measures 10 mm. Overall, the lesion is stable from most recent comparison, but demonstrates mild interval increase in size when compared to more remote study from 6/23/2014. In particular, the lobulated intraspinal component demonstrates increased convexity and measures 10 mm, previously measured 7 mm. There is again significant mass effect on the cord at this level.There is stable disc osteophyte complex at C5-C6 causing mild effacement of the ventral thecal sac and mild-moderate central spinal canal stenosis. There is mild left greater than right foraminal narrowing. There is persistent trace T2/STIR hyperintensity within the right ventral cord, likely minimal myelomalacia. There is also a minimal disc bulge with central prominence at C6-C7 with mild impression on the ventral thecal sac. No significant spinal canal or neural foramina narrowing. Remaining levels demonstrate no significant disk bulge, herniation, spinal canal or foraminal stenosis within the cervical spine. There are multiple small nodular lesions within the soft tissues of the neck bilaterally; majority of them likely reflect lymph nodes, although some of them may relate to schwannomas, grossly unchanged from the prior exam. Redemonstration of previously demonstrated pontine encephalomalacia, partially imaged. There is a partially imaged left vestibular schwannoma measuring 7 x 7 mm, grossly unchanged from prior. There is a partially visualized left infratentorial plaque-like dural-based enhancing lesion measuring 13 x 8 mm, previously 14 x 8 mm may likely represent meningioma unchanged.At the left T4-T5 foramen, there is a 6 x 6 mm enhancing T2 hyperintense likely schwannoma, unchanged from prior.There is a small enhancing T1 hypointense, T2 hyperintense anterior right chest wall lesion, which appears slightly higher than the expected location of the nipple.The right submandibular gland demonstrates questionable hyperenhancement, nonspecific.MRI brachial plexus: There is no significant asymmetry or abnormal signal involving the brachial plexus on the right. There are no masses or lymphadenopathy identified. There are no compressive masses demonstrated. There is no axillary lymphadenopathy. There are no signal abnormalities along the course of the right brachial plexus or neurovascular bundle. There is trace fluid in the glenohumeral joints.
1. Stable schwannoma involving right C2-C3 neural foramen. The left C3-C4 neural foramen schwannoma appears grossly unchanged compared to the prior exam, but interval more rounded configuration and mild enlargement of the medial intraspinal component compared to 6/23/2014 study.2. Stable left C1 intradural extramedullary meningioma.3. Partially imaged stable left infratentorial meningioma and grossly stable left vestibular schwannoma.4. Mild spondylotic changes in the cervical spine, without significant neural foraminal narrowing. Mild-moderate spinal canal stenosis at C5-C6 with right ventral minimal myelomalacia.5. No definite abnormality involving the right brachial plexus.6. Questionable mild hyperenhancement of the right submandibular gland, nonspecific. Please correlate clinically for possible recent sialadenitis.7. Enhancing nodule along right anterior chest wall, which appears slightly higher than the expected location of the nipple. Correlate clinically with direct inspection for possible dermal lesion.
