Does this MRI diagnose the cause of the patient's back pain?
Yes - there is a low T1/T2 lesion consistent with an AVM nidus at the level of T6 with further T2 flow voids throughout the spinal canal.
Intramedullary lesion with prominent T2 flow voids posterior to the T6 vertebral body with linear T2 flow voids throughout the imaged spinal cord. These are predominantly anterior, and indent the cord. There is patchy contrast enhancement and significant blooming. No significant high T2 cord signal.
