Transient right-sided weakness and aphasia. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild periventricular white matter and punctate left thalamocapsular junction T2 hyperintensity. The brain parenchyma otherwise appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and mastoid air cells are grossly unremarkable. However, there is an ovoid T2 hyperintense and T1 hypointense lesion in the posterior neck subcutaneous tissues, which measures up to 25 mm and likely represents a sebaceous cyst. Likewise, a subcentimeter T1 and T2 hypointense nodule in the left frontal scalp may represent an inclusion cyst. There is also a partially-imaged left parotid tail mass that measures at least up to 21 mm. There is a punctate right maxillary sinus retention cyst.
1. Mild periventricular white matter and punctate left thalamocapsular junction T2 hyperintensity may represent chronic small vessel ischemic disease, but no evidence of acute intracranial hemorrhage, mass, or acute infarct.2. A partially-imaged left parotid tail mass may represent a Warthin tumor, but is incompletely characterized. Dedicated imaging of this region may be useful.
