Clinical History: 
This 67-year-old man presented to the neurology department with increasing dizzy and weakness for approximately six months, together with restricted movements of the left upper and lower extremity.

Diagnosis:
A glioma in upper part of right thalamus.

MR Technique: 
Scans were acquired at 1.5 T MR unit using a 8-channel head coil. (A) Axial pre-contrast spin echo T1-weighted (TR/TE 375/14.2ms, 320×192 matrix) and (B) fast spin echo T2-weighted (TR/TE 3900/84ms) scans are displayed, in addition to (C) axial and (D) coronal post-contrast spin echo T1-weighted scans. The slice thickness was 5 mm in each instance.

Imaging Findings:
An irregular intraaxial lesion is displayed in the upper part of right thalamus, with accompanying vasogenic edema in the adjacent white matter. The mass extends to the lateral ventricle, and compresses and infiltrates adjacent brain tissue. On post contrast scans, the tumor has prominent enhancement, predominantly nodular in character, with no enhancement in the adjacent area of vasogenic edema.
