There is a left paravertebral mass lesion, extending from the T7 - T11 vertebral levels. The mass is soft tissue density, and also demonstrates small foci of calcification. There is some associated scalloping of the left side of the adjacent thoracic vertebral bodies, indicating a slow growing lesion. No bone erosion or destruction. There is no extension into the neural exit foramen, or widening of the intercostal spaces.
The appearance favours a neurogenic tumour, likely arising from the sympathetic trunk.
