Overview

Head CT scan may be helpful in the diagnosis of primary central nervous system lymphoma. Findings on CT scan suggestive of primary central nervous system lymphoma include supratentorial hyperattenuating, enhancing, hemorrhaging mass with subependymal extension crossing the corpus callosum.[1] Chest, abdomen, and pelvic CT scans may be used to exclude any occult systemic disease from the spread of primary central nervous system lymphoma.[2]

Head CT

  • Head CT scan may be helpful in the diagnosis of primary central nervous system lymphoma. Findings on CT scan suggestive of primary central nervous system lymphoma include:[1]
  • Enhancement on both CT scan and MRI is pronounced and usually homogeneous. Even with larger lesions, there is little mass effect for size and limited surrounding vasogenic edema.
  • Low grade tumors differ from the more common high-grade primary central nervous system lymphoma in several ways:[1]
  • Deep locations and spinal involvement is more common
  • Contrast enhancement is absent, irregular, or only mild
  • Disseminated meningeal/intraventricular disease is uncommon, it is observed in 5% of cases at presentation and usually in high grade cases.[1]
  • It should be noted that in patients who are immunocompromised (typically HIV/AIDS or post-transplant), enhancement is more heterogeneous.[1]

Chest, Abdomen, and Pelvic CT

  • Chest, abdomen, and pelvic CT scans may be used to exclude any occult systemic disease from the spread of primary central nervous system lymphoma.[2]
