Abstract

Various manifestations of brain involvement for patients with virus-associated hemophagocytic syndrome have been reported. Here, we report on the sequential magnetic resonance (MR) findings of acute demyelination of the entire brain with subsequent brain atrophy in a follow-up study of a 25-month- old boy who was admitted with fever and then diagnosed with infectious mononucleosis and EBV-associated hemophagocytic syndrome. We also review other conditions that should be included in the differential diagnosis of this disease.

Figure

  • Fig. 1 Marrow biopsy section of the patient with EBV-associated hemophagocytic syndrome. (A) There are several macrophages with phagocytosis of erythrocytes and lymphocytes (arrows) on hematoxylin and eosin stains (× 400). (B) Immunohistochemical staining with panmacrophage marker CD68 shows abundant macrophages (× 400).

  • Fig. 2 (A-C) Axial FLAIR images of the brain show high signal intensities of the entire white matter in both hemispheres, including the corpus callosum, internal capsule and middle cerebellar peduncle, suggesting a fulminent demyelinating process. The preservation of white matter volume without a mass effect and a relative sparing of the subcortical U-fibers are also noted.

  • Fig. 3 Follow-up MR findings after two months with chemotherapy. (A-C) Axial FLAIR images of the brain show partial resolution of high signal intensities of the entire white matter and the progression of atrophy at the previously-involved site.
