Brain stem glioma (MR).

PROTOCOL:

T1W – Sagittal & axial scans
T2W – Axial & coronal scans
FLAIR – Axial scans 

FINDINGS:

-Revealed:
• An intra axial mass in the right side of pons and right cerebellar peduncle with measurement of about 32 x 30 mm (best seen in the sagittal image # 14 with contrast).
• Mild narrowing of right cerebellopontine angle (giving suggestion of intra axial rather than extra axial lesion).
• Compression of the upper part of the fourth ventricle.
• No affection to basilar artery.
• Faint heterogeneous with cystic component surrounded by ring enhancement (best noted in image # 16 sagittal views with contrast).
• Till the time of this study; no conization.


Brain Parenchyma shows normal grey white matter differentiation and signal intensities.  No focal mass lesion is seen.
-Lateral and third ventricles are normal in size and position. Septum is in midline.  There is no midline shift.
-Basal cisterns, cortical sulci and gyri are normal in appearance.
-Corpus callosum shows normal MR morphology.
-Fourth ventricle is normal in size and is midline in position.


OPINION:

• In light of above mentioned MR signs and the age of the patient; picture is suggestive of brain stem glioma affecting the right side of the pons and right cerebellar peduncle.
• Enhancement of the lesion gives impression of high grade tumor rather than low grade one.
