Physiological instability is linked to mortality in primary central nervous system lymphoma: A case-control fMRI study.

Hum Brain Mapp 2022 May 11. Epub 2022 May 11.

Oulu Functional Neuroimaging, University of Oulu/Oulu University Hospital, Oulu, Finland.

Primary central nervous system lymphoma (PCNSL) is an aggressive brain disease where lymphocytes invade along perivascular spaces of arteries and veins. The invasion markedly changes (peri)vascular structures but its effect on physiological brain pulsations has not been previously studied. Using physiological magnetic resonance encephalography (MREG ) scanning, this study aims to quantify the extent to which (peri)vascular PCNSL involvement alters the stability of physiological brain pulsations mediated by cerebral vasculature.

An Update on Neurosurgical Management of Primary CNS Lymphoma in Immunocompetent Patients.

Front Oncol 2022 20;12:884724. Epub 2022 Apr 20.

Department of Neurosurgery, Medical University of Innsbruck, Innsbruck, Austria.

Primary central nervous system lymphomas (PCNSL) are rare CNS tumors that harbor a conspicuously longer diagnostic delay compared to other malignant brain tumors. The gold standard for diagnosis is stereotactic biopsy to acquire tissue for histopathological analysis and therefore neurosurgery plays a central role when reducing the diagnostic period is mandated. However, histopathological diagnosis could be complicated if the patient was preoperatively exposed to corticosteroids. Read More

Isolated CNS relapse of medullary aggressive high-grade B-cell lymphoma on F-FDG-PET/CT.

Eur J Hybrid Imaging 2022 May 3;6(1). Epub 2022 May 3.

Radiology Department, Mater Misericordiae University Hospital, Eccles Street,, Dublin 7, Ireland.

This is a case of high-risk, aggressive, high-grade medullary B-cell lymphoma presenting with new onset of neurological dysfunction following initial complete response to the standard chemoimmunotherapy. A whole-body re-staging PET using fluorodeoxyglucose (F-FDG) integrated with computed tomography (FDG-PET/CT) performed with clinical suspicion of arachnoiditis, eloquently demonstrated unequivocal multifocal FDG uptake by the spinal cord without evidence of systemic recurrence, leading to a clinical diagnosis of secondary CNS lymphoma, which is a rare complication of DLBCL with ominous prognosis. Four cycles of Modified-MATRIX protocol resulted in a halt in fulminant course of the disease and the patient experienced slight reversal of the neurological deficits, although not deemed clinically fit for a repeat FDG-PET/CT due to his poor general well-being.

Radiation exposure by medical X-ray applications.

Ger Med Sci 2022 31;20:Doc06. Epub 2022 Mar 31.

University of Duisburg-Essen, Institute for Health Care Management and Research, Essen, Germany.

Radioactive material and ionising radiation play a central role in medical diagnostics and therapy. The benefit of ionising radiation is opposed by the risk of irreparable damage of the human organism. This risk, especially for developing malign neoplasms, has particularly been investigated in the population surviving the atomic bombing of Hiroshima and Nagasaki, but also increasingly in persons with occupational or medical exposure to ionising radiation.

Acta Biomed 2022 03 21;92(S4):e2021416. Epub 2022 Mar 21.

Pediatric Neurology, Pediatric University Department, Azienda Ospedaliera Universitaria Pisana, University of Pisa, Italy.

Posterior Reversible Encephalopathy Syndrome (PRES) is characterized by acute neurological symptoms with typical imaging features, primarily in the territories of the brain supplied by the posterior circulation, probably due to vasogenic edema. Both clinical and imaging features are generally reversible. We report a 13-year-old girl affected by Nodular Sclerosis Classical Hodgkin Lymphoma stage IIIB into complete remission, with a recurrence and autologous bone-marrow transplantation, who has been treated with an anti-CD30 monoclonal antibody, brentuximab-vedotin.

A CT-based radiomics model to predict subsequent brain metastasis in patients with ALK-rearranged non-small cell lung cancer undergoing crizotinib treatment.

Thorac Cancer 2022 Jun 18;13(11):1558-1569. Epub 2022 Apr 18.

State Key Laboratory of Oncology in South China, Guangzhou, China.

Background: Brain metastasis (BM) comprises the most common reason for crizotinib failure in patients with anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC). We hypothesize that its occurrence could be predicted by a computed tomography (CT)-based radiomics model, therefore, allowing for selection of enriched patient populations for prevention therapies.
