RING-ENHANCING LESIONS IN THE BRAIN: A COMPREHENSIVE CASE SERIES AND DIAGNOSTIC REVIEW

Aims: The aim of this study is to evaluate the effectiveness of MRI in detecting and characterizing ring-enhancing lesions in the brain. The goal is to establish MRI as a critical tool for early detection and precise management of brain lesions, ultimately improving patient outcomes. A series of cases with denitive diagnosis based on clinical, microbiological or pathological evidence were retrieved from our hospital database and their radiological images reviewed. Multiple etiologies of cerebral ring-enhancing lesions will be discussed. Imaging features will mainly focus on those shown on MRI. : The study was conducted retrospectively at the Department of Radiodiagnosis, J Materials And Methods JM Medical College, Davangere, Karnataka. Imaging of patients was performed using a PHILIPS 1.5T MRI machine. Various advanced sequences of MRI were employed to distinguish among the various ring enhancing lesions such as pyogenic abscess, tuberculoma, neurocysticercosis, pilocytic astrocytoma, glioblastoma and multiple sclerosis. MRI plays a vital role in identifying ring-enhanc Conclusion: ing lesions in the brain due to its superior imaging resolution and contrast sensitivity. This advanced imaging technique helps differentiate between various potential causes, such as tumors, infections, or inammatory conditions. Early and accurate detection through MRI facilitates timely intervention, enabling targeted treatment and improving patient prognosis. Its ability to provide detailed anatomical information makes MRI indispensable for effective management of brain lesions.
