There is no evidence of intracranial hemorrhage or acute infarct. There is also unchanged encephalomalacia in the adjacent left pons and medial left temporal lobe. The ventricular system is unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable. There is moderate mucosal thickening in the bilateral maxillary sinuses. There is volume loss of the left sided muscles of mastication due to denervation.
