Overview
Other diagnostic studies for primary central nervous system lymphoma include magnetic resonance spectroscopy, magnetic resonance perfusion, scintigraphy, stereotactic biopsy, and polymerase chain reaction.[1][2][3][4]
Other Diagnostics Studies
Magnetic Resonance Spectroscopy
- Magnetic resonance spectroscopy may be diagnostic of primary central nervous system lymphoma. Findings on MR spectroscopy suggestive of primary central nervous system lymphoma include:[1]
- Large choline peak
- Reversed choline/creatinine ratio
- Markedly decreased N-Acetylaspartate (NAA)
- Lactate peak may also be observed
Magnetic Resonance Perfusion
- Magnetic resonance perfusion may be diagnostic of primary central nervous system lymphoma. Findings on MR perfusion suggestive of primary central nervous system lymphoma include a modest increase in relative cerebral blood flow (rCBV), much less marked than in high-grade gliomas, where angiogenesis is a prominent feature.[1]
Scintigraphy
- Findings on scintigraphy suggestive of primary central nervous system lymphoma include:[1]
- Thallium 201: increased uptake
- C11 Methionine PET: increased uptake
Biopsy
- Stereotactic biopsy is usually performed to confirm a diagnosis of primary central nervous system lymphoma, especially in people who do not have AIDS.[2]
Bone Marrow Biopsy
- Bone marrow biopsy may be performed to detect metastases of primary central nervous system lymphoma to the bones.[3]
Polymerase Chain Reaction
Polymerase chain reaction (PCR) of the cerebrospinal fluid (CSF) may be performed to look for positive Epstein-Barr virus DNA in patients with primary central nervous system lymphoma, to establish the association with the virus.[4]
