Left-sided weakness Again seen is evidence of cerebellar tonsillar ectopia, which measure up to 5 to 6 mm on the right and 4 to 5 mm on the left. Subtle differences in measurement compared to recent brain MRI may be related to differences in slice thickness. CSF spaces in the posterior fossa are mildly diminished.There is a prominence of the central canal throughout the cervical cord with more focal dilatation/syringohydromyelia measuring 1.6 x 1.1 mm at the mid C2 level and 1.8 x 2.4 mm at the mid C3 level (AP and transverse dimensions).Incidentally noted are multiple small perineural cysts involving the bilateral neural foramina throughout the cervical spine. T1 hyperintense lesion involving the T2 vertebral body is consistent with a hemangioma. There is a small focus of low T1 and low T2 signal involving the right posterior lateral aspect of the C3 vertebral body which may represent a sclerotic lesion and nonspecific. No abnormal enhancement within the cord or spine within the limitations of mildly motion degraded sequences. Vertebral body heights in the cervical spine are normal. There is loss of normal cervical lordosis; alignment is otherwise maintained. There is mild narrowing of the spinal canal on a congenital basis. There also mild degenerative changes as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: No significant compromise to the spinal canal or neural foramina.C4-5: Small disc osteophyte complex. No significant compromise to the spinal canal or neural foramina.C5-6: Small disc osteophyte complex. No significant compromise to the spinal canal or neural foramina.C6-7: Small disc osteophyte complex. No significant compromise to the spinal canal or neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina.There is significant enlargement of the thyroid gland with right-sided nodule measuring up to 6 cm in the craniocaudal dimension.
1. Cerebellar tonsillar ectopia and small cervical syringohydromyelia, findings which are compatible with Chiari I. Please see details above.2. No significant spinal canal or neural foraminal stenosis at any level in the cervical spine.3. Partially imaged goiter with right-sided thyroid nodule measuring up to 6 cm in the craniocaudal dimension. Suggest ultrasound for further evaluation.
