Title
MRI of the Pituitary/Sella Without and With Intravenous Contrast
Clinical History
Patient-specific — populated from user input at report time. Shows "None" if not provided.
Comparison
No prior studies available for comparison.
Technique
Multi-planar MRI of the brain and sella was obtained utilizing axial diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps, sagittal T1-weighted images, and coronal FLAIR images of the whole brain. High-resolution sagittal and coronal T2-weighted and T1-weighted images of the sella were obtained without contrast. Following intravenous contrast administration, dynamic coronal contrast-enhanced imaging of the pituitary and sella, sagittal and coronal high-resolution images of the sella, and T1-weighted axial images of the whole brain were acquired.
Findings
Multiplanar and dynamic contrast-enhanced MRI of the pituitary and sella was reviewed.
Pituitary Gland:
The pituitary gland demonstrates normal size, morphology, and signal intensity on all pulse sequences. Normal enhancement is noted on dynamic contrast-enhanced imaging.
Sellar and Suprasellar Region:
There is no evidence of sellar or suprasellar mass. No mass effect upon the optic chiasm is identified.
Pituitary Stalk:
The pituitary stalk is midline in location and demonstrates normal appearance.
Optic Nerves and Chiasm:
The optic nerves and optic chiasm are normal in appearance without abnormal enhancement or compression.
Cavernous Sinuses:
The cavernous sinuses demonstrate normal MR signal characteristics bilaterally. Normal flow voids are noted within the cavernous portions of the internal carotid arteries bilaterally.
Ventricles and Sulci:
The ventricles and sulci are age-appropriate in size and configuration.
Intracranial Brain Parenchyma:
No abnormal areas of enhancement are identified throughout the brain. No restricted diffusion to suggest acute ischemia is present. No intracranial hemorrhage, mass, hydrocephalus, midline shift, or herniation pattern is identified.
Corpus Callosum:
The corpus callosum appears well-formed.
Pineal Region:
The region of the pineal recess is unremarkable.
Brainstem and Posterior Fossa:
The brainstem, posterior fossa, and cervicomedullary junction are normal.
Vascular Structures:
The vascular flow voids at the base of the brain are maintained. Normal flow voids are maintained throughout.
Calvarium:
No suspicious expansile or destructive calvarial lesions are identified.
Paranasal Sinuses and Mastoid Air Cells:
The visualized paranasal sinuses and mastoid air cells are clear.
Impression
Normal multiplanar and dynamic contrast-enhanced MRI of the pituitary gland and sella turcica. No evidence of sellar or suprasellar mass. Normal intracranial structures without acute abnormality.
