8 (25):41518-41528. In patients with immunodeficiency or immunosuppression, other lesions, such as toxoplasmosis, cryptococcosis, metastasis, and pyogenic abscess, may have the same ring-enhancing appearance as that of CNS lymphoma. Of patients with primary lymphoma, 75-85% present with supratentorial tumor. J Clin Oncol. On T2-weighted MRIs, the appearance is that of an isointense-to-hyperintense mass. Mabray MC, Cohen BA, Villanueva-Meyer JE, Valles FE, Barajas RF, Rubenstein JL, et al. [13, 11, 14, 15] MRI scans typically show a single or multiple poorly demarcated masses, more or less deeply located within the brain parenchyma.These masses demonstrate uniform intense gadolinium enhancement with little or no … [Medline].

For a lymphoma of the brain or the spinal cord, you usually have an MRI scan every 3 to 4 months, for up to 2 years. The performance of MR perfusion-weighted imaging for the differentiation of high-grade glioma from primary central nervous system lymphoma: A systematic review and meta-analysis. Clinical value of abnormal findings on brain magnetic resonance imaging in patients with intravascular large B-cell lymphoma. Maximum standardized uptake value (SUVmax) has been shown to be higher in PCNSL than in gliomas.

Calcifications do not occur in lymphoma, except rarely in patients who have undergone prior radiation therapy. Similarly, 18F-FDG PET can identify degenerative diseases, multiple sclerosis, infectious diseases, and cerebral infarction. 15 (6):8500-8504. 2017 Sep - Oct. 36 (5):298-303. 1994. Carbon-11 methionine or 18-fluorodeoxyglucose positron emission tomography (18F-FDG PET) may show increased uptake within the tumor tissue. [Medline]. AJR Am J Roentgenol. Sagittal T1-weighted contrast-enhanced MRI reveals 2 rim-enhancing lesions in this patient with HIV infection. 4. Magnetic resonance imaging (MRI) is the examination of choice for CNS lymphoma because of its high sensitivity and multiplanar capability.
The incidence of NHL has doubled over the last 20 years because of the increase in AIDS-related lymphoma and the use of immunosuppressive drugs with organ transplantation and cancer chemotherapy.

[Medline]. 152:177-186. Tumors of the Nervous System. If such findings are seen in patients with AIDS, lymphoma must be differentiated from cytomegalovirus ependymitis; if such findings are encountered in patients who do not have AIDS, lymphoma must be differentiated from metastatic neoplasm, such as carcinoma of the lung or breast. Secondary systemic and primary CNS lymphomas have similar imaging characteristics. Application value of CT and MRI in diagnosis of primary brain lymphoma. [Full Text].

Axial gadolinium-enhanced T1-weighted MRI reveals the rim-enhancing lesions typical of HIV infection.
Involvement of the corpus callosum is highly suggestive of CNS lymphoma, but such involvement also occasionally occurs with anaplastic glioma and metastatic neoplasm. 2002 Batchelor T, Loeffler JS. Imaging of lymphoma of the central nervous system, spine, and orbit. 1,2 The frequency of secondary CNS lymphoma in patients with systemic lymphoma varies and is highly … 2018.
