Name of the Patient : Abc Xylmn / M / 65 yrs.
Referred by : Dr. Abc Xyzrankar.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O right sided hemiparesis with dysarthria since 1 month.
Known diabetic/hypertensive.

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 and coronal images with magnetization transfer.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is seen a fairly large, well marginated, iso to hypointense (as compared to normal white matter), extraaxial mass lesion along the left fronto-parietal convexity. This lesion appears relatively hypointense on the T2 Weighted images. Resultant sulcal space effacement is noted, with mild perilesional edema in the underlying brain parenchyma and compression and inferior displacement of the body of the left lateral ventricle. This lesion is well demarcated from the underlying brain parenchyma by a CSF cleft. Linear flow-voids at the periphery of this lesion most likely represents blood vessels. This lesion appears dural based.



After contrast administration, there is uniform enhancement of the above described lesion, as well as the overlying dura. A dural tail is well identified. The lesion is seen to measure approximately 4.2 x 8.7 x 3.2

An ill-defined, hyperintense signal on the T2 Weighted and FLAIR images in the left paraatrial region may represent an ischemic lesion.

Prominent perivascular spaces are noted in the brain parenchyma on either side.

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

The cerebellar folia appear prominent.

There is no other focal area of abnormal enhancement in the brain parenchyma or the meninges.

Inflammatory changes are noted in the right maxillary antrum.

IMPRESSION :

A fairly large, extraaxial, approximately 4.2 x 8.7 x 3.2 cms sized uniformly enhancing mass lesion along the left fronto-parietal convexity as described, most likely represents a meningioma.
