Primary Inflammatory demyelinating pseudotumor in the left frontal lobe with meningeal involvement presenting as malignant neoplasms

Background:Tumor-like demyelinating lesion is a rare form of IP,often indistinguishable from brain tumors on CT or MR imaging.Case presentation:We report here a case of pathologically confirmed tumor-like demyelinating lesions.The clinical manifestations,image feature and pathology of this case are also discussed together with a review of the relevant literature.Conclusion:The correct diagnosis of tumor-like demyelinating lesion mainly depends on the postsurgical histopathologic examinations.We suggest complete resection of the intracranial lesion and involved dura,followed by administration of short term oral prednisolone therapy will be good for preventing recurrence.
