case_images: Diffuse infiltration of atypical lymphoid cells observed via hematoxylin and eosin (HE) staining (a) (bar = 20 mum). Immunohistochemical staining of the atypical lymphoid cells was positive for CD3 (b), CD30 (c), and negative for anaplastic lymphoma kinase (ALK) (d) (bar = 50 mum).

case_images: Immunohistochemical staining of these cells was positive for CD3, CD30, and CD45 and negative for CD20 (Figure 1).
case_images: Magnetic resonance imaging (a)-(c) revealed a 4 cm lesion in the corpus callosum (indicated by the arrows). Panel (a) shows a fluid-attenuated inversion recovery image; (b) and (c) are T1-weighted images.

case_images: Brain magnetic resonance imaging (MRI) revealed a 4 cm lesion in the corpus callosum (Figure 2).
case_images: Irregularly-shaped lymphocytes in the patient's cerebrospinal fluid stained positive for CD3 (a) and CD 30 (b) (bar = 10 mum).
