Primary central nervous system lymphoma (PCNSL) is a rare brain tumor. This study found PCNSL often presents in the sixth decade with cognitive decline and headache, with a poor prognosis.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Primary central nervous system lymphoma (PCNSL) is a rare extranodal non-Hodgkin lymphoma.
- PCNSL accounts for approximately 4% of all primary brain tumors.
Purpose of the Study:
- To investigate the clinical characteristics, diagnosis, and prognosis of PCNSL.
- To identify factors influencing survival in PCNSL patients.
Main Methods:
- Retrospective review of 24 patients diagnosed with PCNSL between 1990 and 2010.
- Diagnosis confirmed via magnetic resonance imaging (MRI) and surgical confirmation.
- Data analyzed included patient demographics, clinical presentation, diagnostic methods, pathology, and survival outcomes.
Main Results:
- The median age at diagnosis was 59.3 years, with most patients being immunocompetent.
- Common presenting symptoms included cognitive decline (33.4%) and headache (25%).
- B-cell lymphoma was the most common pathology (91.6%). Mean survival was 12.8 months, with a 1-year survival rate of 37.5%.
Conclusions:
- PCNSL typically affects individuals in their sixth decade, presenting with cognitive decline and headache.
- A single intracranial lesion was observed in 75% of cases.
- Preoperative clinical status emerged as the most critical prognostic factor for survival.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
