Abstract

Inflammatory pseudotumor arising in the meninges of spinal cord is extremely rare and most of the cases have occurred in the lung. A case of a thoracic inflammatory pseudotumor causing myelopathy and mimicking an extradural mass is presented. The lesion was demonstrated by magnetic resonance imaging, and total removal of the mass was performed. Its histology was characterized by infiltration of three kinds of cells; histiocytes with slight epithelioid appearance, plasma cells with numerous Russell bodies, and lymphocytes. Although extrapulmonary inflammatory pseudotumors have been reported, the authors believe this is the second case of this type tumor in the spinal cord meninges.
