 Exam is limited by motion artifact and suboptimal field of view.Brain: No diffusion weighted abnormality. No evidence of intracranial hemorrhage. The gray-white matter differentiation is preserved. The signal intensity and morphology of the cerebral, cerebellum and pons are within normal limits. No evidence of mass, mass effect, or hydrocephalus. There is no abnormal intracranial enhancement. No extra-axial fluid collections. Tonsils are at the level of the foramen magnum, stable from prior study. Mucosal thickening of the left maxillary sinus, bilateral sphenoid sinuses, and opacification of left ethmoid air cells, new from prior study. Trace opacification of bilateral mastoid air cells. The orbits are unremarkable. Flow voids are present within the major vessels indicating patency. Pituitary: Exam is limited by motion artifact and suboptimal field of view. Pituitary gland is small, similar to the prior study, which can be normal for patient's age. The size and signal intensity of the pituitary stalk is well demarcated and enhanced. The optic chiasm and hypothalamus demonstrate normal signal intensity and morphology.
1.Exam is limited by motion artifact and suboptimal field of view. Within this limitation, there are no gross abnormalities of the brain or pituitary gland.2.Paranasal sinus opacification as above.
