Low Grade Pericytoma in the Left Thalamus

A 31 year old female presented with transient episodes of numbness and tingling in her right face, arm and leg. MRI: T1 C- (a) No definite signal abnormality is identified in the left thalamic low grade glioma. T1 post (T1 C+ b) : Post contrast images demonstrate no enhancement in the region of the known mass. This is typical of a low grade glioma. T2 (c): This T2 weighted image shows a unilateral well circumscribed area of increased signal in the anterior left thalamus. There is no significant mass effect on the adjacent structures. FLAIR (d): This FLAIR image from her MRI demonstrates (with slightly better clarity than the T2 weighted image) a unilateral well circumscribed area of increased signal in the anterior left thalamus. There is no significant mass effect on the adjacent structures.
