Aim:
This study aims to investigate the role of diffusion-weighted imaging (DWI) in enhancing the diagnostic accuracy of adult posterior fossa tumors.
Materials And Methods:
A prospective cross-sectional study was conducted involving 20 patients with suspected CNS posterior fossa tumors. MRI scans were performed using a 1.5 Tesla machine with appropriate sequences, including DWI. Data analysis was performed using descriptive statistics.
Results:
The study revealed that the majority of posterior fossa tumors occurred in the age group of 61-70 years, with medulloblastoma being the most common tumor subtype. Male patients were more prevalent than females, and DWI showed hyperintensity in the majority of lesions. The reported sensitivity and specificity of DWI were high, indicating its effectiveness in tumor evaluation.
Conclusion:
In conclusion, this study provides valuable insights into the epidemiology, clinical features, and radiological characteristics of adult posterior fossa tumors. It underscores the significance of advanced imaging techniques like DWI in improving diagnostic accuracy and guiding clinical management decisions for these challenging neoplasms.
