 The heterogeneously enhancing, well circumscribed ovoid mass extending from the T4-5 to the T5-6 level measures 4.7 x 3.1 x 3.4 cm, not significantly changed when measured similarly. There is no evidence of extension into the spinal canal. The lumbar spine is in normal alignment, with a normal lumbar lordosis. There are central endplate depressions from T11 to L1 and mild anterior wedging of the L1 vertebral body are stable. The vertebral body and disc heights are otherwise well-maintained. The T10 hemangioma is unchanged, as are two well-defined areas of low T1 and T2 signal in the T7 vertebral body with subtle enhancement. The spinal cord signal is normal throughout. There is no significant disc bulge, herniation, spinal canal, or foraminal stenosis within the thoracic spine. There is a small right renal probable cyst only apparent on the localizer images.
1. Stable size and appearance of the right thoracic paraspinous mass most compatible with a peripheral nerve sheath tumor.2. Unchanged hemangioma in the T10 vertebra and enhancing lesions in the T7 and T9 vertebral bodies, which may represent atypical hemangiomas. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
