Mid-back pain, with question of a dural AV fistula found incidentally after CT abdomen for diarrhea and abdominal pain. Dural AVF seen on outside MRI in May, 2015. Please compare to outside MRI and evaluate. MRI C-spine:Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained. Bone marrow signal is within normal limits. The cervical spinal cord has normal signal characteristics and overall morphology.Degenerative changes are seen in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: No significant compromise to the spinal canal or neural foramina.C4-5: No significant compromise to the spinal canal or neural foramina.C5-6: Disc osteophyte complex and uncovertebral hypertrophy causes mild right neuroforaminal stenosis. There is no significant left neuroforaminal or central canal stenosis.C6-7: Mild disc osteophyte complex and uncovertebral hypertrophy with mild left neuroforaminal stenosis. There is no significant right neuroforaminal or central canal stenosis.C7-T1: No significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.MRI T-spine:Coursing along the anterior and posterior aspect of the lower thoracic spine spinal cord mostly between the T10-11 and T11-12 levels is a enhancing vascular structure partially surrounds the left hemicord at the T10-11 level. This vascular structure appears to enter the spinal canal at the right L1-L2 neural foramen and is suspicious for an AV fistula.The thoracic spine is in normal alignment. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal caliber. There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the thoracic spine.
1.Findings are suspicious for an AV fistula involving the lower thoracic cord, predominately at T10-11 and T11-12 levels. There are no significant cord signal changes appreciated to suggest cord edema. Spinal arteriogram may be of benefit if clinically appropriate.2.There are mild degenerative changes in the cervical spine.
