Unlike brain tumors, demyelinating pseudotumors respond well to steroid hormones. There are only a few reported cases of intracranial demyelinating pseudotumors in the literature. In this case report, we present the diagnosis and treatment of demyelinating pseudotumor in a patient whose condition was initially misdiagnosed as an astrocytoma. Based on the literature and our case, we formulated an outline for the differential diagnosis of demyelinating pseudotumor and astrocytoma. A timely and correct diagnosis of demyelinating pseudotumor would avoid blind surgery, radiotherapy and chemotherapy, which are used to treat brain tumors.
