Bone lesion: T9 is the 9th thoracic vertebral body. In ct the image can be altered or "windowed" to depict certain types of tissue in greater detail, such as bone. Lytic means less bone, sclerotic is more dense bone. In the spine the more common mixed lesions would be hemangiomas or fibrous dysplasia.

I cannot tell if there is reason for concern without images, sorry. Typically, if the lesion is worrisome you will know as more imaging or a biopsy would be recommended.

Mixed density: This means there is an area in the 9th thoracic body (mid back) which has areas which are lower density (lytic) and higher density (sclerotic) than normal bone at that location. There are many reasons for this appearance. A thoracic spine MRI of this area, probably with and without contrast, may be helpful.
