Name of the Patient : Abc Xyzbai lmn / F / 88 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O loss of memory since 1 month.
H/O glomus jugular tumor diagnosed in 0000. Received radiotherapy.
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 Gradient coronal images.
5 mm thick T1 Weighted sagittal 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.
SOME IMAGES SHOW PATIENT MOTION INSPITE OF SEDATION.
There is a large ill-defined, mass lesion predominantly in the left frontal, right frontal and left temporal lobe anteriorly. This lesion is hypointense to the white matter on the T1 Weighted images and is seen to turn heterogeneously hyperintense on the proton, T2 Weighted and FLAIR images. There is surrounding edema with mass effect and effacement of the adjacent sulci. The corpus callosum appears involved with the rostrum, genu and
anterior portion of the body of the corpus callosum displaced slightly posteriorly and to the right with mild shift to the right side. There is compression upon the frontal horn of both the lateral and third ventricles. The middle cerebral artery on the left side is slightly displaced posteriorly with lateral displacement of the ACA branches. After administration of contrast, there is thick ill-defined peripheral enhancement of this lesion which measures appproximately 6.8 x 6.2 x 7.0 cms
There is dilatation of the body of the right lateral ventricle. There is prominence of cerebral cortical sulci.
A small ill-defined intermediate signal on the T1 Weighted images is seen in the jugular foramen which turns hyperintense on the T2 Weighted and STIR images and shows heterogenous enhancement on contrast administration.
The basal cisternal spaces are unremarkable.
1. Right glomus jugular tumor.
2. A large ill-defined, mass lesion predominantly in the left frontal, right frontal and left temporal lobe anteriorly with extensions and contrast enhancement as described is not specific for a single etiology. This most likely represents a neoplastic process. A metastasis or a primary neoplasm like glioma or lymphoma should be considered in the differential diagnosis.
As compared to the previous MRI of December 0000 there is no change in the right glomus jugular lesion.
