Female, 74 years old, with inflammatory lesions in the posterior fossa. Evaluate. Changes related to prior left cerebellar biopsy are again seen. A focus of susceptibility in the left cerebellar hemisphere at the site of biopsy is unchanged. No edema or pathologic enhancement is observed. T2 hyperintensity in the pons, with associated minimal susceptibility effect, also shows no convincing interval change.Minimal scattered periventricular T2 hyperintense foci are unchanged. No new intracranial lesions are detected. No evidence edema, mass effect or restricted diffusion is seen. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra axial fluid collections. The ventricles are normal in size and morphology.
1.Findings related to left cerebellar biopsy are unchanged.2.Signal abnormality in the pons is also unchanged.3.No pathologic enhancement or edema is seen to suggest active inflammation.
