Primary central nervous system lymphoma (PCNSL) risk is greatly increased in immunosuppressed HIV-infected people. Using data from the United States transplant registry linked with 17 cancer registries (1987-2014), we studied PCNSL and systemic non-Hodgkin lymphoma (NHL) in 288,029 solid organ transplant recipients. Transplant recipients had elevated incidence for PCNSL compared with the general population (standardized incidence ratio=65.1; N=168), and this elevation was stronger than for systemic NHL (standardized incidence ratio=11...

BACKGROUND: Ventriculoperitoneal shunt (VPS) placement has been implicated in extraneural metastasis of many primary central nervous system tumors. Reported cases include, but are not limited to, medulloblastoma, germ cell tumor, astrocytoma, oligodendroglioma, lymphoma, ependymoma, melanoma, and choroid plexus tumors. However, a literature review reveals no reported cases of extraneural metastasis of solitary fibrous tumor/hemangiopericytoma (SFT/HPC). CASE DESCRIPTION: Here we report the case of a 34-year-old man with recurrent intracranial malignant SFT/HPC who had undergone surgical tumor resection and subsequent placement of a VPS for obstructive hydrocephalus in 2004...

OBJECTIVE: Primary central nervous system lymphoma (PCNSL) is a specific type of non-Hodgkin lymphoma with poor prognosis. The rare incidence of this disease and difficulty to obtain sufficient tissue material impede deep research into PCNSL. However, application of modern molecular techniques makes it possible to find biological characteristics exclusive to PCNSL. Therefore, we systematically reviewed the latest research progress on biological characteristics and pathogenesis of PCNSL...

Primary central nervous system (CNS) lymphomas account for 13-20% of the posttransplant lymphoproliferative disorders (PTLD) and rank among the most aggressive conditions. Reduction of immunosuppressive therapy should be mandatory to treat PTLD, but this is rarely used as the only therapy option. Chemotherapy regimens for PTLD involving the CNS most commonly include high-dose rituximab and high-dose methotrexate and/or cytarabine. The efficiency only of discontinuation of immunosuppressive therapy for PTLD does not exceed 5-10%, but there are no literature data on its efficiency for PTLD involving the CNS...

Primary mediastinal large B-cell lymphoma (PMBCL) is a distinct type of large B-cell lymphoma. In this type of the disease, the neoplastic process is located in the anterior and superior mediastinum, frequently with compression of the superior vena cava and with tumor invasion into the adjacent organs and tissues: the pericardium, lung, pleura, etc. Despite the fact that in PMBCL progression, there may be involvement of extranodal organs, such as the kidney, adrenal glands, liver, and central nervous system, bone marrow (BM) injury is generally absent...

Currently the differential diagnosis of anaplastic meningiomas often is quite complex. An interpretation of the data of radiological studies does not allow the exclusion of diseases with similar clinical course and character of a lesion, such as primary lymphoma and tuberculosis of the central nervous system, neurosarcoidosis and others. The article presents a clinical case, representing a rare and difficult to diagnose variant of anaplastic meningioma with extremely aggressive nature of the current and widespread involvement of the brain and spinal cord...

OBJECTIVE: Primary central nervous system (CNS) lymphoma is an aggressive and fatal extranodal non-Hodgkin lymphoma (NHL) jailed in CNS at initial diagnosis. Its prognosis is poor and the disease has a fatal outcome when compared with systemic NHL. A few baseline risk stratification scoring systems have been suggested to estimate the prognosis mainly based on serum lactate dehydrogenase (LDH) level, age, Karnofsky performance score (KPS), involvement of deep brain structures (DBS) and cerebrospinal fluid protein concentration...

(18)F-fluoro-2-dexoy-D-glucose-positron emission tomography (PET)/computed tomography (CT) is a useful imaging technique for monitoring the treatment response in lymphoma cases. We investigated the value of interim brain PET/CT (I-PET/CT) for monitoring the response to intensive methotrexate-based chemotherapy in primary central nervous system lymphoma (PCNSL) patients with diffuse large B cell lymphoma (DLBCL). Of the 76 PCNSL patients treated with intensive methotrexate and cytarabine chemotherapy between September 2006 and December 2012, 66 patients with DLBCL were included in this study...

OBJECTIVE: Our purpose was to evaluate the diagnostic performance of diffusion-weighted imaging, the relative minimum apparent diffusion coefficient (rADCmin) in differentiating primary central nervous system lymphomas (PCNSLs) from glioblastomas (GBMs) and inflammatory demyelinating pseudotumors (IDPs). MATERIALS AND METHODS: Magnetic resonance images were reviewed retrospectively in 82 patients including 39 PCNSLs, 35 GBMs, and 8 IDPs. Regions of interest were drawn around the tumor on contrast-enhanced axial images; these images were transferred onto coregistered ADC maps to obtain the ADCmin, and the normalized ADCmin ratios (rADCmin) were calculated using the formula rADCmin = ADCmin of the lesion / ADCmin of the normal white matter...

Primary intraocular lymphoma (IOL) has a propensity for central nervous system (CNS) relapse within 2 years of initial diagnosis, affecting clinical outcome. To reduce CNS relapse, we performed the combination treatment protocols of intravitreal methotrexate injections, methotrexate-based systemic induction chemotherapy and consolidation high-dose cytarabine and reduced-dose whole brain radiation therapy (rdWBRT, 23·4 Gy) for B-cell primary IOL with or without newly diagnosed CNS involvement. All patients underwent longitudinal brain magnetic resonance imaging (MRI) and cognitive assessment for evaluation of treatment-induced leucoencephalopathy...

Whether the poor prognosis of primary central nervous system lymphoma (PCNSL) compared with systemic diffuse large B cell lymphoma (DLBCL) is attributable to the immune privilege of the intracerebral location or to intrinsic differences in the biological characteristics of two types of lymphoma remains unclear. Monocyte chemoattractant protein 1 (MCP-1) is essential to support tumor cell survival and growth, and the present study aimed to compare MCP-1 expression in PCNSL and peripheral DLBCL. The present study included 19 patients with PCNSL and 16 patients with DLBCL, all of whom had tissue diagnosis and lymphoma tissue samples available for analysis...

Central nervous system immune reconstitution inflammatory syndrome (CNS-IRIS), which occurs most often in HIV-infected patients, is an exacerbation of inflammatory reactions related to opportunistic infections as well as primary CNS malignancies both of which mostly occur in HIV-infected patients. However, differential diagnoses are challenging both clinically and radiologically. We describe a patient with CNS-IRIS due to toxoplasmosis whose (11)C-methionine uptake suggested lymphoma but whose arterial spin-labelling MRI led to the correct diagnosis...

The true incidence of light chain deposition disease (LCDD) restricted to the central nervous system (CNS) is unknown. To our knowledge only 7 cases of LCDD restricted to the brain have been previously reported. We herein describe an unusual example. A 44-year-old man presented with a history of ischemic retinopathy in 2004 and left lower extremity hypoesthesia in 2007 that progressed gradually to left-sided weakness and numbness in the 2 years prior to his hospitalization in 2015. A stereotactic brain biopsy was performed, displaying nonspecific hyaline deposits of amorphous "amyloid-like" material involving deep brain white matter and vessels...
