A study on various patterns of cranial metastases on MRI

Abstract

Introduction: The radiological imaging plays a primary role to detect, localize, and diagnose the lesion. Various modalities which can be used are radiography, Computed imaging, Magnetic resonance imaging, Nuclear medicine and angiography. Except MRI, all other modalities involve exposure to radiation. Methodology: Fifty (n = 50) patients, who underwent surgery with histopathological diagnosis were included in the study. Written informed consent was obtained from all the patients for the study. Detailed clinical history was taken in all the patients. Results: Intraaxial was the most common compared to the extra axial location. Supra tentorial was most common than infra tentorial. Skull vault involvement was seen in 10% cases and dural metastases were seen in 18% cases. Conclusion: Brain metastasis is common among patients with systemic cancer. Brain metastasis (MET) is thought to occur when the primary tumor acquires the ability to migrate away from the primary site and travels to the brain.
