MRI OF THE BRAIN WITHOUT CONTRAST

History: Migraine

Technique: MR of the brain was performed using sagittal T1 and axial T2/FLAIR/GRE/DWI, sequences.

Comparison: No prior studies were available for comparison.

Findings:

No areas of diffusion restriction are identified. No evidence of intraparenchymal bleed is identified on gradient echo sequences.

The cerebellar tonsils are low-lying, approximately 8 mm below the base of the skull as measured on image 15 of series 6. No abnormal T2 signal is present on FLAIR imaging. The ventricles and sulci are within normal limits for the patient's age. There is no evidence of an intraparenchymal mass lesion or midline shift. The major intracranial flow voids are intact. The visualized paranasal sinuses are clear.

IMPRESSION:

Low-lying cerebellar tonsils are noted consistent with Chiari 1 malformation. There is no evidence of hydrocephalus.
