Very strange: Not certain what to make of the disparity between the CT scan and the MRI. In some cases, a lesion is so small that it is missed by the artifact created by the thickness of the MRI slices. I would ask your doctor if an MRI of the brainstem with "thin slices" might be reasonable to confirm/refute the CT--with and without contrast. Take care and stay healthy!
