Axial T1-weighted gadolinium enhanced brain MRI showing (A) bilateral, homogenously enhancing periventricular masses in the posterior fossa in February 2008; (B) recurrent leptomeningeal enhancement within the cerebellar folia in June 2010 and (C) no abnormal enhancement or parenchymal involvement in April 2013 with isolated cerebrospinal fluid disease.

Neuroimaging revealed bilateral, homogenously enhancing periventricular masses in the posterior fossa (Figure 1A).
Association between cerebrospinal fluid glucose by lumbar cistern and clinical symptomatology. Cerebrospinal glucose concentration by lumbar cistern dural puncture prior to, during and following the 38 treatments with intrathecal rituximab (25 mg) showing the close association with clinical symptomatology..  : Indicates intrathecal rituximab (25 mg) administration..
