Multiple ring-enhancing lesions are one of the most commonly encountered neuro imaging abnormalities. Widely available imaging techniques, computed tomography and magnetic resonance imaging (MRI) are used to detect these lesions. Objective was to study the characteristic imaging findings in various ring enhancing lesions and the role of MR spectroscopy in its evaluation. It is a retrospective study conducted on 50 patients at Bapuji hospital, Davangere from Nov 2009 to Nov 2011 over a period of 2 years. Out of the 50 patients evaluated, 22 cases were tuberculomas, 16 were NCC, 5 abscesses, 5metastasis, 1case of pilocyticastrocytoma and 1 case of tumefactive demyelination. MRI is the most sensitive modality in the characterization of intracranial ring enhancing lesions–RELs. It shows characteristic imaging findings which helps in differentiating the various RELs. MRI playsacritical role in patient management by suggesting the correct diagnosis based on characteristic imaging findings.
