MRI BRAIN
MRI BRAIN: Multiplanar and multi-echo MRI of the brain was performed without administration of intravenous contrast.
FINDINGS:
POSTERIOR FOSSA:
- Cerebellum and brainstem are normal.
- Cerebellar folia are normal.
- No evidence of tonsillar herniation.
- Pons and medulla show normal signal intensity.
- No focal SOL is seen. Basal and CP angle cisterns are normal.
- Fourth ventricle is central and is normal in shape.
- Both the IAMs are normal and symmetrical.
- VII and VIII nerve complex appear normal.
- Bilateral mastoid air cells are normal.
SELLA:
- The pituitary gland shows a normal shape, appearance and signal intensity pattern. No intra sellar or supra sellar mass seen. Stalk is in the midline. Sellar structures are normal.
- No evidence of abnormal SOL or calcification is seen.
- Clinoid processes and Sella floor are normal.
- Cavernous sinuses are normal in size. Sellar margins are well maintained. No bony lytic lesion or break in continuity.
- Supra sellar and chiasmatic cisterns are normal. No para sellar abnormality. No hypothalamic lesion.
- Sphenoid sinus appears normal. Visualized basal cisterns are within normal limits.
SUPRATENTORIAL:
- Few punctate and mild confluent FLAIR hyperintense foci are seen in bilateral periventricular white matter and centrum semiovale without diffusion restriction or gradient blooming. Rest of the bilateral cerebral hemispheres appear normal.
- Grey and white matter differentiation is maintained.
- Basal ganglia and thalamus appear normal.
- Bilateral insular cortex and Sylvian fissures appear normal.
- No congenital mal formation noted.
- No acute infarct or bleed is seen.
- No focal SOL is seen.
- No abnormal parenchymal / meningeal / cisternal enhancement is seen.
- Midline septa not shifted. No evidence of brain herniation.
- Ventricular system is not dilated and appear symmetrical. No intraventricular or ependymal lesions. Aqueduct appears normal in size.
- CSF spaces and fissures are well maintained.
- No evidence of extra-axial collection is seen.
INTRACRANIAL ARTERIES AND VENOUS SINUSES:
- Flow voids of the major vessels viz; intracranial ICA, basilar artery & their branches and of the venous sinuses are well seen.
- No evidence of aneurysm or sinus thrombosis. No arteriovenous malformation noted.
CALVARIUM AND SCALP:
- Bony calvarium shows normal signal and diploic space. No MRI evidence of fracture or SOL is seen.
- No defect , sclerotic or lytic skull lesion noted.
- Skull base appears grossly normal. Overlying scalp is normal. No focal lesion or swelling noted.
ORBITS AND PARANASAL SINUSES:
- Visualized bony orbits appear normal. Visualized intraorbital contents show no obvious abnormality
- Visualized eye globes and lens show normal signal intensity.
- Paranasal sinuses are well pneumatized without any fluid collection/mucosal thickening.
IMPRESSION:
- Small vessel chronic ischemic/changes.
Suggested clinical correlation.
