Findings:
No intra- or extra-axial mass lesion or collection is identified. The ventricles and sulcal spaces are within normal limits. The midline structures are normal with no midline shift.
The brain parenchyma is unremarkable. No abnormal signal on the susceptibility-weighted images or diffusion/ADC images is identified. No abnormal intra or extra-axial enhancement was noted on the postcontrast study.
The anterior pituitary is normal in size, shape, morphology, and signal intensity. Posterior pituitary bright spot is orthotopic in position. On the dynamic post-contrast study, no abnormal lesion is seen within the anterior pituitary.
The infundibular stalk is central in position and normal in thickness.
The pituitary fossa, the cavernous sinus, bilateral internal carotid arteries and the basilar artery are unremarkable.
The orbits, paranasal sinuses and mastoid air cells are clear.
No bony abnormality is seen. The craniocervical junction is normal.
Conclusion:
MRI of the brain without evidence of any intracranial mass lesion. No obvious pituitary adenoma.
