Name of the Patient : Abc Xyzar B. Nagaolmn / M / 62 yrs.
Referred by : Dr. Abc Xyz Mehta.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O disorientation with memory loss since 15 days with an episode of convulsion on 00.00.00 followed by loss of consciousness for half an hour. Now patient is in semiconscious state.

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 and Fast Scan (T2 ) coronal 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 fairy large, well-marginated mass lesion in the left deep temporal lobe. This lesion is predominantly hypointense on the T1 Weighted images and appears hyperintense on the proton, T2 Weighted and Flair images. A tumor nodule is noted along the medial margin of the lesion which is of intermediate signal on the proton, T2 Weighted and Flair images. There is perilesional edema with effacement of the left Sylvian fissures and sulcal spaces in the fronto-parietal region. Compression of the third and lateral ventricles is noted.
Scan-00008/26



After administration of contrast there is a thick rim enhancement of the above described lesion and uniform enhancement of the tumor nodule along the medial margin of the lesion. The tumor is seen to extend posteriorly upto the atrium of the left lateral ventricle, with enhancement of the ependymal lining of the atrium of the left lateral ventricle. The tumor is seen to measure approximately 3.0 x 5.5 x 4.2 cms.

An approximately 9.0 mms diameter sized enhancing, satellite lesion is noted in the left temporal lobe, lateral to the above described lesion (scans 00006 - 102/7, 103/10).

The right lateral and fourth ventricles are normal.

The basal cisternal spaces are unremarkable. There is prominence of the cerebellar folia bilaterally. No obvious vascular anomaly is identified on this study.

Incidentally noted is pansinusitis.

IMPRESSION :

A fairly large, approximately 3.0 x 5.5 x 4.2 cms sized mass lesion in the left deep temporal lobe with signal characteristics and mass effect as described is not specific for a single etiology. A glial cell tumor/metastasis may be considered as differential diagnosis.
