Name of the Patient : Abc Xyz Chlmn / F / 23 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O headaches with vomiting and slight weakness of the RUE and RLE since 1 day.
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.
4 mm thick Fast Scan (T2 *) coronal images.
After administration of contrast the following parameters were used :
5 mm thick T1 Weighted axial and 4 mm thick T1 Weighted coronal images with magnetization transfer.
5 mm thick T1 Weighted sagittal images.
Few images show patient motion.
There is seen a fairly large, approximately, 3.2 x 2.3 x 1.9 cms sized rim enhancing mass lesion in the left cerebellar hemisphere, inferiorly. This lesion is iso to slightly hypointense to normal white matter on the T1 Weighted images and appears hypointense on the proton and T2 Weighted images. There is mild perilesional edema with effacement of the sulcal spaces in the left cerebellar hemisphere, the left ambient cistern and mild indentation on the fourth ventricle.
A subcentimeter diameter hypointense lesion is seen in the region of the tectal plate on the T1 Weighted images and this is seen to enhance after contrast administration.
Both the lateral and third ventricles are normal. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
An approximately, 3.2 x 2.3 x 1.9 cms sized rim enhancing mass lesion in the left cerebellar hemisphere, inferiorly, follows the signal characteristics of a granulomatous lesion like a tuberculoma. The possibility of this being a neoplastic lesion like a PNET is less likely.
A subcentimeter diameter sized lesion is also noted in the region of the tectal plate.
