Evaluate for brainstem abnormality: Speech apraxia, frequent aspiration. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brainstem, cerebellum, and brain parenchyma appear unremarkable, including patchy areas of bilateral parietal terminal zones of myelination. There is no abnormal intracranial enhancement. 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. There is a 10 mm diameter, well-defined, cystic lesion in the left sphenoid triangle. There is fluid within the bilateral mastoid air cells and scattered paranasal sinus fluid and mucosal thickening, which may be attributable to intubation. The orbits are grossly unremarkable.
1. The brainstem is unremarkable. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. A 10 mm diameter, well-defined, cystic lesion in the left sphenoid triangle likely represents an inclusion cyst.
