Female, 73 years old, with brain lesion seen on prior imaging, compare to prior study. The intrinsically T1 hyperintense lesion seen within the left temporal lobe on the prior examination has significantly decreased in size now measuring 12 x 6 mm, previously 26 x 20 mm. The rim of the lesion shows strong susceptibility artifact and the internal contents are T1 and T2 hyperintense. Edema and mass effect related to this lesion seen on the prior examination have resolved. No pathologic enhancement is detected in the vicinity of this lesion or elsewhere intracranially.Patchy periventricular and pontine T2 hyperintensity is again seen, similar to the prior examination. No areas of parenchymal signal abnormality are seen. No restricted diffusion is detected. There is no evidence of any new intracranial fluid collection. The ventricular system is normal in size and morphology.
1.Interval decrease in size of a lesion in the left temporal lobe which is compatible with a parenchymal hematoma. Previously seen edema and mass effect have resolved. There is no associated pathologic enhancement or other evidence to suggest an underlying lesion.2.Evidence of chronic microvascular ischemic disease is seen with no new intracranial findings.
