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...

BACKGROUND ALK gene rearrangements as oncogenic drivers have been described in many cancers, including inflammatory myofibroblastic sarcoma (IMS). The first-generation ALK inhibitor was limited in its ability to cross the blood-brain-barrier to treat brain metastasis. Drug-resistance invariably develops over time in ALK-rearranged tumors, which leads to disease progression. The newer generations of ALK inhibitors are designed to have higher potency in ALK inhibition and improved CNS penetration. CASE REPORT We report a rare case of pulmonary IMS with ALK-1 gene rearrangement and multiple brain metastases as initial presentation...

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...

Primary CNS lymphoma (PCNSL) is a rare form of extranodal non-Hodgkin lymphoma that is typically confined to the brain, eyes, and cerebrospinal fluid without evidence of systemic spread. The prognosis of patients with PCNSL has improved during the last decades with the introduction of high-dose methotrexate. However, despite recent progress, results after treatment are durable in half of patients, and therapy can be associated with late neurotoxicity. PCNSL is an uncommon tumor, and only four randomized trials and one phase III trial have been completed so far, all in the first-line setting...

Gliomas are the most common primary brain tumors of the central nervous system (CNS). Due to the poor prognosis of glioma patients, it is urgent to develop more effective therapies. Deltex-3-like (DTX3L), also known as B-lymphoma and BAL-associated protein (BBAP), has been reported to play an important role in the progression of many tumors. This study aimed to investigate the clinical significance and biological function of DTX3L in human glioma. Clinically, the protein expression level of DTX3L is increased in glioma tissues compared with that observed in normal brain tissues...

Central diabetes insipidus (DI) is a rare clinical entity characterized by low circulating levels of antidiuretic hormone (ADH) presenting with polyuria and volume depletion. Pituitary surgery is the most common cause of central DI in adults. Pituitary and hypothalamic disease, particularly invasive neoplasms, rarely cause DI, being idiopathic cases responsible for the majority of non-surgical cases. HIV patients, especially those with poor virulogical control, are prone to the development of CNS neoplasms, particularly lymphomas...

Bruton tyrosine kinase (BTK) links the B-cell antigen receptor (BCR) and Toll-like receptors with Nuclear factor kappa B (NF-κB). The role of BTK in primary CNS lymphoma (PCNSL) is unknown. We performed a Phase 1 clinical trial with ibrutinib, the first-in-class BTK inhibitor, for patients with relapsed or refractory CNS Lymphoma. Clinical responses to ibrutinib occurred in 10/13 (77%) PCNSL patients, including five complete responses. The only PCNSL with complete ibrutinib resistance harbored a mutation within the coiled-coil domain of Caspase Recruitment Domain Family Member 11, a known ibrutinib resistance mechanism...

Primary central nervous system T-cell lymphoma (PCNSTCL) is rare, accounting for 2% of CNS lymphomas. We report the first case of PCNSTCL with aberrant expression of CD20 and CD79a in an 81-year-old man with a left periventricular brain mass. A biopsy revealed dense lymphoid infiltrate consisting of medium-sized cells in a background of gliosis and many histiocytes. The lymphoid cells were positive for CD2, CD3, CD7, CD8, T-cell intracellular antigen-1, granzyme B, CD20, and CD79a and negative for CD4, CD5, PAX-5, OCT-2, BOB-1, human herpes virus-8, and Epstein-Barr virus-encoded small RNAs...
