Other specified disorders of muscle [M62.89] / Headache [R51], Reason for Study: ^Reason: avm, History: headache with left sided weakness Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal. Left distal vertebral artery is hypoplastic. Bilateral Pcom arteries and Acom artery are patent.There is no evidence of arterial aneurysm. No intracranial arterial luminal stenosis.Spine MRIThere is normal cervical lordosis. The cranial-cervical junction is normal. There is normal thoracic kyphosis and lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The cord signal is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal stenosis, cord compression or myelopathy. The conus medullaris terminates at the level of L1. The paraspinal soft tissues and musculature are unremarkable.There is no evidence of abnormal enhancement, cord compression or mass. There is diffuse bulging of disc at the level of L45 otherwise unremarkable intervertebral discs.
1. Normal brain MRA.2. Diffuse bulging of disc at the level of L45, otherwise no remarkable Cervical, thoracic and lumbar MRI. Spinal cord appears to be normal.
