Name of the Patient : Abc Xyzaiglmn / F / 27 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

Known C/O oligodendroglioma.
H/O left frontal craniotomy on 00.00.00.
C/O seizures (3 episodes) since July 0000.
For follow up.

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.

After administration of contrast the following parameters were used :

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

OBSERVATION :

There is evidence of a left frontal craniotomy.

There is a mass lesion in the left high frontal region. This lesion is mildly hypointense with few hyperintense areas within it on the T1 Weighted images. This is seen to turn hyperintense on the proton, T2 Weighted and FLAIR images. A small cystic/necrotic component is seen on the FLAIR images. There is mild effacement of the adjacent sulci. The adjacent gyri appear thick and are hypointense to normal gray matter on the T1 Weighted images and turn hyperintense on the proton, T2 Weighted and FLAIR images.
- 2 - Scan-00007


On administration of contrast, there is faint enhancement at the periphery of the cystic/necrotic component. Also seen is enhancement of the meninges adjacent to the surgical site.

A lacune is noted in the right occipital lobe.

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 :

In a known C/O oligodendroglioma, the MRI features are suggestive of :

1. Post-operative status.

2. Residual lesion in the left frontal lobe as described.
