Name of the Patient : Abc Xyzlmn / M / 48 yrs.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

Known C/O pineal tumor. Diagnosed in April 0000.
C/O loss of sensations with weakness of the RLE since 8-10 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.

3 mm thick FLAIR coronal images.

MR cisternogram was obtained in the sagittal plane.

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 seen an approximately 3.0 x 2.5 x 1.8 cms sized (in maximum dimensions) mass lesion in the region of the pineal gland. This lesion shows mixed signal characteristics and is predominantly hypointense to normal white matter, with a peripheral hyperintense rim on the T1 Weighted images. On the proton and T2 Weighted images the lesion is relatively hypointense. A very small cystic component is noted along its lateral margin.

There is indentation on the tectal plate superiorly with mild compression of the posterior third ventricle and the aqueduct. Minimal indentation on the superior surface of the midbrain is noted.
..2/.






There is mild dilatation of both the lateral and anterior third ventricles. The fourth ventricle is normal. The tip of the shunt tube is noted at the body of the right lateral ventricle abutting the septum pellucidum.

The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

After administration of contrast, there is near homogeneous enhancement of the previously described lesion in the pineal region. There is no other area of abnormal enhancement in the brain parenchyma or the meninges.

IMPRESSION :

As compared to the previous CT Scan dated 00.00.00, there is no significant change in the size of the pineal region tumor. There is however a slight increase in the size of both the lateral ventricles and anterior third ventricle.
