Female, 42 years old, with headache and cranial 6 palsy. Assess for dural thickening/enhancement. Also history of lumbar spine epidural fluid collection, assess for resolution. Brain:Brain parenchymal morphology and signal characteristics are within normal limits. No evidence of parenchymal edema or mass effect is seen. No restricted diffusion is detected.On postcontrast imaging, diffuse pachymeningeal thickening and enhancement shown on outside imaging has resolved. There is no evidence of any pathologic parenchymal or extra-axial enhancement on the present examination.No evidence of intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The ventricles are normal in size and morphology.Lumber spine:Spinal alignment is anatomic. Vertebral height and morphology are normal. No pathologic marrow replacement or evidence of marrow edema is seen.The visualized spinal canal is patent and unremarkable. Ventral epidural collections seen previously at L2-3 and L5 have resolved. No new epidural collections are detected.Visualized spinal cord, conus and cauda equina are within normal limits.The paraspinal soft tissues are normal.Intervertebral disk height and morphology are unremarkable. No evidence of disk bulge or herniation is seen. Mild facet hypertrophy is demonstrated at lower lumbar levels. No evidence of any significant spinal canal or neuroforaminal stenosis is detected.
1.Interval resolution of previously seen diffuse pachymeningeal thickening and enhancement. Evaluation of the brain is unremarkable.2.Interval resolution of previously seen ventral epidural collections in the lumbar spine. No new or significant abnormalities are detected.
