 The thoracic spine is in normal alignment, with a normal thoracic kyphosis. The thoracic vertebral body and disk heights are well-maintained. There is a compression deformity at the L1 vertebral body, similar to the prior study. The spinal cord is of normal caliber and signal. Again noted is an enhancing lesion in the left lateral side of the T10 vertebral body overlying the T10-T11 neural foramen, measuring 16 x 12 mm, (series 1201, image 17), similar to 5/10/2016 allowing for measurement technique differences and 10 x 11 mm on 9/2/2013. There is no clear extension into the neural foramen. There are lesions within the T3, T8, T9, and T11 vertebral bodies demonstrating high T1 and T2 signal, compatible with hemangiomas and unchanged from the prior study. No worrisome focal marrow signal abnormality is appreciated. There are nonenhancing cystic lesions within the neural foramina of T10-T11 bilaterally, the right neural foramen at T8-T9 and T9-T10, and the left neural foramen at T1-2, appearing similar to the prior study and likely representing perineural cysts.There is effacement of the dorsal thecal sac at the T10-T11 level related to facet arthropathy and ligamentum flavum thickening. There is otherwise no significant spinal canal stenosis at any level.
1. Enhancing paraspinous lesion adjacent to the left T10-T11 neural foramen is unchanged since 5/10/2016 and gradually enlarged since more remote studies. Differential includes neurogenic tumors such as schwannoma.2. Chronic L1 compression fracture is also unchanged.
