Intrathecal chemotherapy is often administered for prophylaxis and treatment of central nervous system involvement in hematological malignancies. However, it may rarely cause neurotoxicity as a side effect. We herein report a 74-year-old woman with diffuse large B-cell lymphoma including a spinal lesion. ⋯ Intrathecal treatment was discontinued, and she was administered vitamin B12 and folic acid, along with steroid pulses. However, her symptoms did not improve. Intrathecal chemotherapy-induced myelopathy is rare, but may be irreversible; therefore, clinicians should be aware of this potential complication.

Cryoglobulins are immunoglobulins that precipitate in cold conditions. Type I cryoglobulinemic vasculitis is associated with hematological malignancies. ⋯ Bortezomib+dexamethasone therapy resulted in a rapid decrease in cryoglobulin and improvement in the symptoms of cryoglobulinemic vasculitis. In refractory type I cryoglobulinemic vasculitis, treatment of the underlying gammaglobulinopathy should be considered.

Objectives Chronic progressive neuro-Behcet's disease (CPNB) is characterized by progressive deterioration leading to disability. Methotrexate (MTX) has been shown to have beneficial effects on CPNB. However, while infliximab has been found to be effective for patients with inadequate responses to MTX, the appropriate timing for the introduction of infliximab remains unclear. ⋯ The functional disability grades after infliximab treatment were significantly correlated with the intervals from the onset of CPNB to the introduction of infliximab (r=0.6177, p=0.0476). Conclusion The results indicate that the delayed introduction of infliximab leads to irreversible functional disability in CPNB. Thus, it is recommended that infliximab be administered as soon as possible for CPNB patients with inadequate responses to MTX.

Case Reports
Clinical Response of Primary Malignant Pericardial Mesothelioma with Peritoneal Dissemination to Nivolumab.
Malignant pericardial mesothelioma (MPM) is extremely rare, and peritoneal dissemination has not yet been reported. There is no consensus regarding appropriate pharmacological treatment for MPM, including immune checkpoint inhibitors (ICIs). ⋯ The patient was treated with nivolumab and showed a clinical response despite several complications, such as renal dysfunction and performance status deterioration. This case report provides suggestive information for the diagnosis and ICI therapy of a rare type of mesothelioma.
