Summary
Primary central nervous system lymphoma (PCNSL) in the posterior cranial fossa exhibits distinct MRI features. Diffusion-weighted imaging (DWI), ADC values, and magnetic resonance spectroscopy (MRS) aid in accurate PCNSL diagnosis.
Area of Science:
- Neuroradiology
- Oncology
- Neuroimaging
Background:
- Primary central nervous system lymphoma (PCNSL) can occur in the posterior cranial fossa.
- Accurate diagnosis of PCNSL in this location is crucial for effective treatment.
Purpose of the Study:
- To summarize MRI imaging findings of PCNSL in the posterior cranial fossa.
- To enhance diagnostic accuracy for PCNSL in this specific anatomical region.
Main Methods:
- Retrospective analysis of 15 PCNSL posterior cranial fossa cases.
- Evaluation of MRI plain and enhanced imaging, DWI, and MRS.
- Inclusion of lesion site, number, and imaging characteristics.
Main Results:
- 15 cases included: 10 single, 5 multiple lesions (total 25).
- Lesions found in cerebellum, midbrain, fourth ventricle, pons; varied signal intensities and enhancement patterns.
- DWI showed high signals in 5 cases; ADC values averaged (0.62±0.095)×10⁻³ mm²/s; MRS revealed Lip peaks in 2 cases.
Conclusions:
- PCNSL in the posterior cranial fossa presents specific MRI characteristics.
- DWI, ADC value, and MRS are valuable tools for improving PCNSL diagnostic rates.
