Name of the Patient : Abc Xyzi Slmn / M / 48 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O weakness of the LUE since 4 days.

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.

After administration of contrast the following parameters were used :

5 mm thick T1 Weighted axial and coronal images with magnetization transfer.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is a well circumscribed lesion in the right frontal region (in the precentral gyrus) which measures approximately 2.4 x 2.3 x 2.1 cms. This lesion is hypointense on the T1 Weighted images with a hyperintense periphery. The centre is seen to turn hyperintense on the proton, T2 Weighted and FLAIR images and the periphery turning hypointense. Surrounding edema is noted with slight effacement of the adjacent sulci. On administration of contrast there is thick peripheral enhancement of the lesion.
Scan-00003


There is no other area of abnormal enhancement.

Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

IMPRESSION :

The MRI features are suggestive of a well circumscribed lesion in the right frontal region measuring approximately 2.4 x 2.3 x 2.1 cms. with thick peripheral enhancement. This is not specific for a single etiology.

The possibilities to be considered are :

1. Infective process like an abscess.

2. Neoplastic process like a glial cell tumor or metastasis.

A follow up scan would be worthwhile.
