Cerebral toxoplasmosis occurred in a 34-year-old patient with chronic myelogenous leukemia following bone marrow transplantation. The clinical picture included headaches, nuchal rigidity, and right-sided hemiparesis during a course of disseminated cutaneous herpes zoster. The diagnosis of toxoplasmosis was based on serologic evidence and typical computed tomography scan of the brain as well as clinical improvement following specific anti-Toxoplasma treatment. To the best of our knowledge, this is the first report of cerebral toxoplasmosis in Israel.

EBV-associated lymphoproliferative disorder (LPD) is a rare but serious complication in marrow transplant recipients. A 31-year-old Japanese woman in the second chronic phase of CML received an allogeneic BMT from her HLA 2-locus-incompatible 62-year-old father. Around day +200, she developed EBV-LPD of the right parieto-temporal lobe which caused slowly progressive left hemiparesis. Two courses of donor lymphocyte transfusions (DLT) of 10(6)CD3+ T cells/kg of body weight failed to suppress her central nervous system (CNS) EBV-LPD. The patient died of recurrent blastic crisis of CML. This case suggests that DLT may be ineffective for the treatment of CNS EBV-LPD.

We report a 78-year-old woman who had multiple leukemic cell tumors in the brain in the course of chronic myelocytic leukemia (CML). As far as we could survey, such brain tumors were extremely rare. She had been followed because of chronic phase of CML until October, 1998, when she noticed muscle weakness in her left upper and lower extremity. A head MRI revealed multiple masses in the brain, a biopsy of which revealed a tumor of CML cells. Although 40 Gy gamma-knife therapy had reduced the size and numbers of brain tumors, we found recurrence of left hemiparesis and tumors three months after the gamma-knife therapy. Whole brain irradiation therapy (total 30 Gy) was somewhat effective to the tumor and hemiparesis transiently subsided. Thereafter her general condition worsened again, and she died in June, 1999, eight months after the diagnosis of the brain tumors of leukemic cells. We had not seen any other clinical evidence of generalized blastic crisis in this patient. In our case, MRI of the brain showed two patterns of metastases, tumor forming and cortical invasive type. We thought that these two patterns of brain involvement might show different responses to the radiation therapy, and it was characteristic in this patient.

A 76-year-old man, diagnosed with chronic myeloid leukemia in 2010, had been on nilotinib for 7 years. He presented with right hemiparesis in September 2017. He had no history of hypertension, diabetes, hyperlipidemia, heart disease, or smoking. Brain MRI revealed a border-zone infarction of the left cerebral hemisphere and a rapidly progressing severe left internal carotid artery (ICA) stenosis. He was initiated on clopidogrel and bosutinib instead of nilotinib. He presented with right hemiparesis once again in December 2017. Brain MRI revealed the border-zone infarction of the left cerebral hemisphere and a more progressed, severe bilateral ICA stenosis. A carotid ultrasound demonstrated iso-intense and concentrically narrowed ICA on both sides. Carotid artery stenting of the left ICA was performed in February 2018, and clopidogrel was replaced by cilostazol to provide a drug-induced rush. Carotid artery stenting of the right ICA was performed in June 2018 and cervical angiogram demonstrated that there were no residual artery stenoses in the bilateral stent. In recent years, several case reports suggest that tyrosine kinase inhibitors (TKIs) are associated with progressive artery stenosis and cause cerebral infarction. Brain imaging tests should be conducted to evaluate arterial stenosis progression for patients with a history of taking TKI when an arterial vascular event occurs.
