 The study is motion degraded. Fast imaging sequence acquisition was utilized in an attempt to complete a diagnostic study. Given this caveat:There is a left focal cortical abnormality involving the underlying subcortical white matter at the left temporo-occipital junction. It demonstrates T2 hyperintensity (series 1001 image 13, series 1301 image 13, series 1201 image 24). Within the center of the lesion is a linear T1 precontrast focus (series 601 image 13) which appears to correlate with a vessel as demonstrated on susceptibility technique (series 1401 image 60). There is a suggestion of a subtle blush of enhancement along the lateral aspect of the linear T1 precontrast hyperintense focus (series 1601 image 13).There is a solitary punctate focus of T2 hyperintensity along the subcortical white matter of the medial left parietal lobe (series 1301 image 17) without associated mass effect, restricted diffusion, enhancement, or susceptibility abnormality. Given its solitary nature, this is of uncertain clinical etiology or significance.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and left left mastoid air cells are clear. Fluid is again noted within a few right mastoid air cells.
1.There is a left focal cortical abnormality involving the underlying subcortical white matter at the left temporo-occipital junction. It demonstrates T2 hyperintensity (series 1001 image 13, series 1301 image 13, series 1201 image 24).

There is a suggestion of a subtle blush of enhancement along the lateral aspect of the linear T1 precontrast hyperintense focus (series 1601 image 13). The differential diagnosis would most likely include a small vascular malformation versus neoplasm.2. Fluid is again noted within a few right mastoid air cells.
