Name of the Patient : Abc Xyzatidevi Rajlmn / F / 36 yrs.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Brain.
EXAMINATION :
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
5 mm thick FLAIR coronal images.
5 mm thick T1 Weighted sagittal images.
OBSERVATION :
An irregularly defined mass lesion is noted in the region of the medulla and inferior cerebellar vermis. The fourth ventricle at this level cannot be identified separately from the mass lesion.
This lesion is hypointense on the T1 Weighted images and turns hyperintense on the proton, T2 Weighted and FLAIR images. The inferior portion of the lesion is isointense to CSF on the T1 Weighted, T2 Weighted and FLAIR images and hyperintense to CSF on the proton images and would represent a cystic component. It is seen to extend into the upper cervical cord upto the C2 vertebral level.
Multiple curvilinear and punctate signal voids are seen in the region of the mass lesion and would represent blood vessels.
A shunt tube is seen to course through the brain parenchyma with its tip lying in the frontal horn of the left lateral ventricle. Hypointense areas on the T1 Weighted images which turn hyperintense on the proton, T2 Weighted and FLAIR images are seen along the shunt tube in the right parietal lobe. This may represent edema/seepage of CSF.
Hyperintense signal on the FLAIR images is noted in the right frontal region, which may be due to shunt tube insertion through the right frontal burr hole.
The third and the lateral ventricles are otherwise unremarkable.
IMPRESSION :
The MRI features are suggestive of a mass lesion in the region of the medulla and inferior cerebellar vermis as described and most likely represent a hemangioblastoma.
