MR1 HEAD
TECHNIQUE:
Muitipianar SE Ti, FSE T2, FLAIR and gadolinium enhanced images were obtained.
FINDINGS:
A large, expansile focus of intermediate low signal on Ti WI and bright on FLAIR and T2 WI is noted in the midbrain and pons measuring 3.5 x 3.6 x 4.6 cm.
No enhancement is seen upon administration of contrast.
Anteriorly, the mass extends to the prepontine cistern and surrounds the basilar artery.
Posteriorly, it displaces the fourth ventricle but shows no evidence of compression.
There is no extension of the lesion into the medulla and spinal cord.
Both cerebral hemispheres show normal signal intensity. No anormal bright signal intensity changes or enhancement is noted.
Ventricles are normal in size. There are no shifts in the midline cerebral structures.
