Primary Central Nervous System Involvement in Peripheral T-Cell Lymphoma: A Case Report

Area of Science:

• Neuro-oncology
• Radiology
• Hematology

Background:

• Primary central nervous system T-cell lymphoma (PCNSTL) is exceptionally rare.
• Limited case reports exist on PCNSTL imaging characteristics.
• Accurate diagnosis relies on understanding rare tumor presentations.

Observation:

• A patient with peripheral T-cell lymphoma-not otherwise specified was analyzed.
• Magnetic resonance imaging (MRI) was utilized for detailed examination.
• The patient presented with numerous small, nodular, and patchy lesions.

Findings:

• The observed lesions exhibited strong enhancement on MRI.
• These findings are characteristic of PCNSTL, despite its rarity.
• The pattern suggests disseminated neoplastic involvement within the CNS.

Implications:

• This case contributes to the limited literature on PCNSTL imaging.
• Recognizing these specific MRI findings can aid in early diagnosis.
• Further research into PCNSTL's radiological features is warranted.
