Title
MRI of the Orbits and Brain 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 orbits was obtained utilizing axial (T1 FS, T2 FS), coronal (T2 FS, T1) and bilateral oblique T1 FS images without contrast. Following intravenous contrast administration, axial T1 FS, coronal T1 FS and oblique T1 FS images of the orbits were acquired. Brain imaging included axial (T1, DWI, ADC maps) and sagittal (T1) sequences without contrast, and axial T1 images with contrast.
Findings
Multiplanar MRI examination of the orbits and brain demonstrates normal anatomy without evidence of acute abnormality.
Orbital Globes:
The orbital globes are normal in size and symmetric.
Extraocular Muscles:
The extraocular muscles appear unremarkable.
Optic Nerves and Chiasm:
The optic chiasm is normal in size with no evidence of impingement.
Pituitary Gland and Sella Turcica:
The pituitary gland and sella turcica appear within normal limits. The pituitary stalk appears unremarkable.
Cavernous Sinuses:
The cavernous sinuses appear unremarkable bilaterally.
Orbital Soft Tissues:
The orbital soft tissues appear normal.
Ventricles and Sulci:
The ventricles and sulci are normal for the patient's stated age.
Corpus Callosum:
The corpus callosum is well formed and intact.
Cerebral Parenchyma:
No evidence of acute infarction, mass lesion, or abnormal signal intensity within the cerebral parenchyma.
Diffusion-Weighted Imaging:
The diffusion-weighted images and ADC maps show no evidence of acute infarction or restricted diffusion.
Gradient Echo and Susceptibility:
The GRE/T2* images show no evidence of parenchymal hemorrhage or abnormal susceptibility artifact.
Intracranial Collections:
There is no evidence of extra-axial collections or subdural/epidural fluid.
Cerebellum and Posterior Fossa:
The brainstem, posterior fossa, and cervicomedullary junction appear preserved. The cerebellar tonsils appear to terminate above the level of the foramen magnum.
Cerebellopontine Angles:
There is no gross mass lesion in the cerebellopontine angles.
Paranasal Sinuses and Mastoid Air Cells:
There are no fluid levels seen within the paranasal sinuses and mastoid air cells.
Nasopharynx:
The visualized nasopharynx appears normal.
Skull Base and Calvarium:
There is no abnormal bone marrow signal within the skull base, calvarium, and visualized upper cervical spine.
Intracranial Vasculature:
Expected flow-voids are present within the visualized intracranial vessels at the skull base level and dural venous sinuses.
Impression
No evidence of acute infarction, intracranial hemorrhage, space-occupying mass lesion, or midline shift. Normal MRI examination of the brain and orbits.
