Male, 39 years old, status post CSF leak repair with memory loss. Brain:Diffusion-weighted images are unremarkable. No evidence of parenchymal edema or mass effect is seen. No areas of encephalomalacia or parenchymal defects are detected. No pathologic parenchymal or extra-axial enhancement is observed. A small left frontal developmental venous anomaly is detected. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra-axial collections. The ventricles are normal in size and morphology. Partially empty sella is again seen, unchanged.Skull base:Evidence of interval CSF leak repair is again seen along the right aspect of the cribriform plate. There is no longer any obvious nasal cavity fluid contiguous on the right. On the left, a small locule of fluid below the olfactory groove is again seen appearing similar to prior. No evidence of any new pooling or collected fluid is seen in the nasal cavity.The superior ophthalmic veins are prominent, left side more than right. In addition, Meckel's caves are patulous and there appear to be prominent CSF sheaths contiguous of Meckel's cave within the foramen rotundum and foramen ovale bilaterally.
1.No acute intracranial abnormality or other specific findings which would account for the patient's memory loss.2.Findings are seen compatible with interval CSF leak repair along the right cribriform plate.3.Multiple findings are seen including partially empty sella, prominence of the superior ophthalmic veins, and prominence of Meckel's cave and contiguous CSF sheaths which may reflect idiopathic intracranial hypertension.
