OMG and intracranial hemorrhage: When diagnosing our patient with IIH, it was imperative to rule out myelinating oligodendrocyte glycoprotein antibody-associated disease (MOGAD), multiple sclerosis (MS), and other demyelinating diseases such as optic neuritis. Initial brain imaging using computed tomography (CT) without contrast showed no evidence of intracranial hemorrhage but demonstrated the presence of prominent sheath complexes, suggestive of optic neuritis, and a slightly small pituitary gland height for a patient who is 30 years of age.
