Introduction

Background

Before 1970, CNS lymphoma accounted for less than 1% of brain neoplasms. The incidence has increased several-fold since that time, mainly because of AIDS-related immunodeficiency and the use of immunosuppressive drugs with organ transplantation and cancer chemotherapy. Several rare congenital immunodeficiency syndromes may result in CNS lymphoma. These include Wiskott-Aldrich syndrome, X-linked immunodeficiency, immunoglobulin A deficiency, and severe immunodeficiency syndrome.1,2,3,4,5,6,7

Approximately 10-30% of patients with systemic lymphoma have secondary CNS involvement8,9 ; primary lymphomas represent approximately 70-90% of all CNS lymphomas. Secondary systemic and primary CNS lymphomas have similar imaging characteristics. Meningeal involvement occurs commonly in patients with secondary lymphoma; it occurs less frequently in patients with primary lymphoma. Of patients with primary lymphoma, 75-85% present with supratentorial tumor. As many as 50% of patients present with multiple tumor nodules.

Pathophysiology

Almost all CNS lymphomas are non-Hodgkin B-cell tumors. Rarely, patients with human T-cell lymphotropic virus type 1 (HTLV-1) disease develop Burkitt lymphoma or T-cell lymphoma. Typically, lymphoma is represented by histiocytic cells or large immunoblastic cells bearing B-cell surface markers.10,11

Tumor nodules typically develop in the subcortical and subependymal white matter and the corpus striatum. The corpus callosum is frequently involved with tumor extension; a butterfly tumor may thereby involve both cerebral hemispheres.

In cases of secondary lymphoma, spread of tumor occurs from the affected meninges via the perivascular spaces of Virchow-Robin; rarely, secondary involvement with Hodgkin disease occurs. Within the brain substance, the irregular tumor edge extends along perivascular spaces. The spinal cord is frequently affected by secondary lymphoma.

In cases associated with AIDS or other immunodeficiency disorders, lymphoma tumor nodules are often multiple. Infection with Epstein-Barr virus has been suggested as a causative factor in CNS lymphoma.

Frequency

United States

Primary CNS lymphoma now represents as many as 2% of all intracranial neoplasms, 7-15% of primary brain tumors, and less than 1% of non-Hodgkin lymphomas. Approximately 2% of patients with AIDS have CNS lymphoma.

Mortality/Morbidity

For immunocompromised and nonimmunocompromised patients with CNS lymphoma who remain untreated, the mean survival rate is 1-3 months. The mean survival rate for patients who are treated is better for patients without AIDS (18.9 mo) than for individuals with AIDS (2.6 mo).12,13

Race

No racial predilection is known for CNS lymphoma.

Sex

The male-to-female ratio for CNS lymphoma is estimated to be 3:2 in immunocompetent patients and 9:1 in persons with AIDS.14

Age

CNS lymphoma affects persons of all ages; the peak incidence occurs in those aged 40-60 years.

  • Patients with inherited immunodeficiency, such as Wiskott-Aldrich syndrome, tend to develop CNS lymphoma in childhood.
  • Patients with AIDS are likely to develop the tumor in early adulthood.
  • Patients with AIDS-associated primary CNS lymphoma usually have advanced HIV infection, with CD4+ T cell counts of less than 50 cells per millimeter.

Presentation

The clinical presentation of patients with CNS lymphoma is nonspecific and depends on the location of the neoplasm. Patients with CNS lymphoma may present with focal neurologic impairment, cognitive changes, or seizure disorder.

Preferred Examination

MRI is the examination of choice for CNS lymphoma because of its high sensitivity and multiplanar capability. MRI images 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 edema.15

Gadolinium-based contrast agents (gadopentetate dimeglumine [Magnevist], gadobenate dimeglumine [MultiHance], gadodiamide [Omniscan], gadoversetamide [OptiMARK], gadoteridol [ProHance]) have been linked to the development of nephrogenic systemic fibrosis (NSF) or nephrogenic fibrosing dermopathy (NFD). For more information, see the eMedicine topic Nephrogenic Fibrosing Dermopathy. 

NSF/NFD  has occurred in patients with moderate to end-stage renal disease after being given a gadolinium-based contrast agent to enhance MRI or MRA scans. NSF/NFD is a debilitating and sometimes fatal disease. Characteristics include red or dark patches on the skin; burning, itching, swelling, hardening, and tightening of the skin; yellow spots on the whites of the eyes; joint stiffness with trouble moving or straightening the arms, hands, legs, or feet; pain deep in the hip bones or ribs; and muscle weakness. For more information, see the FDA Public Health Advisory or Medscape.

Limitations of Techniques

Although sensitive, MRI characteristics are not specific for CNS lymphoma; however, MRI findings may be suggestive of lymphoma in the proper clinical setting.
