Fig 3.

Atypical features of the eye-of-the-tiger sign. The hyperintense area in the anteromedial globus pallidus has totally disappeared at the anterior commissural level (A, left) but is partly visible at just above that level (A, right, arrow). The dark streaks extend into the hyperintense centers (B, left, arrow). The remaining component of hypointensity is observed as hyperintense stripes (B, right, short arrow). T2-hyperintensity extends into the genu of the internal capsule (B, right, long arrow). The hyperintense areas are unusually located in the whole medial GP (C) and posterior GP (D). The hyperintense center is obscured in a patient with GP calcification (E). y. indicates years of age.
