 BRAIN: There is mild motion degradation of the study. There is no acute infarct, mass effect or midline shift. The cerebellar tonsils remain above the foramen magnum. The rostrum, genu, anterior and midbody of the corpus callosum have formed with hypoplasia of the posterior body and splenium of the corpus callosum. There is mildly colpocephalic appearance of somewhat parallel lateral ventricles. There is no hydrocephalus. There are no definite gray matter heterotopias. The hippocampi are symmetric in signal and volume. There is mild ethmoid and trace sphenoid sinus mucosal thickening. There are small bilateral maxillary sinus air-fluid levels.CERVICAL: There is straightening of the cervical spine with no marrow or cord signal abnormality. There is no suspicious enhancement in the cervical spine. There is no significant disk/endplate degenerative change, spinal canal or neural foraminal stenosis in the cervical spine. The paravertebral soft tissues are unremarkable.THORACIC: The thoracic spine alignment is normal. The bone marrow signal is within normal limits. There is no cord signal abnormality. There is no suspicious enhancement in the thoracic spine. There is mild diffuse epidural lipomatosis in the posterior epidural space essentially throughout the entire thoracic spine with slightly decreased CSF space around the upper and mid thoracic cord. There is no significant disk herniation, or neural foraminal stenosis. There may be trace bilateral pleural effusions.LUMBAR: The last well formed disk space is referred to as S1-2 with the S1 vertebral body lumbarized. There is spina bifida occulta with right-sided hemilamina defect of the L1 vertebral body. The conus terminates at L2, within normal limits and normal ventral motion on prone imaging. There is no meningocele, lipoma or evidence of tethered cord on the prone images. There is no significant spondylolisthesis. The vertebral body and disk heights are preserved. There is no suspicious enhancement within the lumbar spine.There is a nonenhancing 11-mm T2 hyperintense lesion likely consistent with a cyst. There are bilateral extrarenal pelves.
1.Mildly colpocephalic lateral ventricles with posterior corpus callosum hypoplasia. No definite anatomic abnormality to explain patient's seizure.2.Transitional vertebral anatomy with lumbarized S1, and the last well formed lumbar disk referred to as S1-2. If surgery is to be contemplated, correlation with imaging of the entire spine is recommended.3.No MR evidence of tethered cord.4.Spina bifida occulta at L1.5.Small bilateral maxillary sinus air-fluid levels may represent acute sinusitis in the proper clinical setting.6.Suspect trace bilateral pleural effusions.7.11-mm right renal cyst.
