T8 -- T9 level mass. Possible vascular period recommended CTA for further evaluation. Examination demonstrates a dural based high density mass measuring approximately 22 mm in cranial cephalad access in 5-mm in AP access immediately anterior to the superior facet of T8 on the left. There is no evidence of increased vascularity to suggest arteriovenous malformation, dural aVF at this location. This lesion is primarily on the left side however a very small extension of the lesion across the midline to the right is noted. The finding is believed to represent a meningioma. A high density lesion on axial images is more suggestive of calcification rather than enhancement. Review of prior MRI examination demonstrates no abnormal edema of the cord. No definitive increased vascularity within the epidural dorsal fat pad is detected.3D reformatted images of the area of interest were also made.The lesion appears as a calcified intra dural lesion,likely a meningioma.
Dural based intradural extra medullary high density (likely calcification and less likely enhancement) may represent an intracanalicular meningioma. No definitive evidence of increased vascularity to suggest vascular malformation and no evidence of edema of the cord on prior MRI examination from 4 -- 9 -- 2009 was noted.
