Insights

A 14-year-old boy was diagnosed with diffuse large B-cell lymphoma (DLBCL) in his left parietal lobe. This rare pediatric brain tumor required specialized treatment considerations.

Area of Science:

  • Neuro-oncology
  • Pediatric Hematology-Oncology
  • Neuropathology

Background:

  • Primary central nervous system lymphoma (PCNSL) is rare in children.
  • Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of PCNSL.
  • Intracranial masses in adolescents can present with non-specific neurological symptoms.

Observation:

  • A 14-year-old boy presented with headaches and vomiting.
  • Imaging revealed a 2x3 cm left parietal lobe mass.
  • Stereotactic biopsy confirmed diffuse large B-cell lymphoma (DLBCL).

Findings:

  • Cerebrospinal fluid cytology was negative for malignant cells.
  • Bone marrow biopsies were negative, ruling out systemic involvement.
  • Positron emission tomography/computed tomography (PET/CT) scan showed no evidence of extranodal disease.

Implications:

  • This case highlights the importance of considering DLBCL in the differential diagnosis of pediatric brain tumors.
  • The localized nature of the tumor suggests potential for targeted therapy.
  • Multidisciplinary management is crucial for optimizing treatment outcomes in pediatric PCNSL.
