Primary diffuse large B-cell lymphoma of the CNS, with a "Lymphomatosis cerebri" pattern.

Autops Case Rep 2021 Apr 20;11:e2021250. Epub 2021 Apr 20.

Post Graduate Institute of Medical Education and Research, Department of Histopathology, Chandigarh, India.

We describe an unusual case of lymphomatosis cerebri in a middle-aged lady presenting with rapid-onset dementia. The lymphomatous infiltrate, instead of forming mass lesions, percolated throughout the brain parenchyma, which is often missed on a stereotactic biopsy and hence warrants caution and awareness about this entity. The nonspecific symptoms at presentation and a variable picture at imaging make this entity diagnostically challenging. Read More

Characteristics of central nervous system progression in non-small cell lung cancer treated with crizotinib or alectinib.

Cancer Rep (Hoboken) 2021 May 7:e1414. Epub 2021 May 7.

Department of Thoracic Medical Oncology, The Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, Japan.

Background: Most patients treated with anaplastic lymphoma kinase (ALK)-tyrosine kinase inhibitors for ALK-positive non-small cell lung cancer (NSCLC) develop resistance, leading to metastasis, with progression to the central nervous system (CNS) being a primary concern. Although alectinib has better CNS penetration than crizotinib, patients treated with alectinib also develop CNS progression. CNS metastases more likely occurs during crizotinib treatment due to less blood-brain barrier (BBB) penetration capability than alectinib. Read More

Clinical Applications of Magnetic Resonance Spectroscopy in Brain Tumors: From Diagnosis to Treatment.

Radiol Clin North Am 2021 May 23;59(3):349-362. Epub 2021 Mar 23.

Radiology and Imaging Sciences, Emory University, 1364 Clifton Road Northeast BG20, Atlanta, GA 30322, USA.

Magnetic resonance spectroscopy (MRS) is a valuable tool for imaging brain tumors, primarily as an adjunct to conventional imaging and clinical presentation. MRS is useful in initial diagnosis of brain tumors, helping differentiate tumors from possible mimics such as metastatic disease, lymphoma, demyelination, and infection, as well as in the subsequent follow-up of patients after resection and chemoradiation. Unfortunately, the spectroscopic appearance of many pathologies can overlap, and ultimately follow-up or biopsy may be required to make a definitive diagnosis. Read More
