  		Fig 1. MR images of patient on admission. T1-weighted coronal image (A) shows a hyperintense mass in the sellar and the suprasellar regions, suggestive of a subacute bleed. Note that neither the optic chiasm nor the optic tracts reveal evidence of hemorrhage on T1-weighted (A, B) or T2-weighted images (C).

  		Fig 2. MR images of patient on admission day 2. Enlargement of the right optic tract with hyperintensity on T1-weighted (A) and hypointensity on T2-weighted images (B, C) is seen, suggestive of acute bleed. Note mild edema in the left optic tract. A sagittal T1-weighted image (D) reveals hyperintensity of the pituitary adenoma and right optic chiasm.

  		Fig 3. T1-weighted (A) and T2-weighted (B) MR images on admission day 30. Optic tract swelling in the patient has decreased. Both optic tracts are revealed as isointensity on both images.
