Characteristics of Ring enhancing lesions in brain in correlation with MRI and MR spectroscopy

Abstract

Background:The aim of this study was to analyze and identify various characteristic changes of multiple ring-enhancing lesions in the brain on conventional MRI and proton MR spectroscopy which leads to an early diagnosis, treatment, response assessment and minimize the complications in such patients.Materials and method:It is a type of descriptive study, consisting of 50 patients that were suspected clinically with ring-enhancing lesions were referred to the department of Radio-diagnosis and underwent scanning in 1.5 Tesla MRI over a period of 2 years.Results:Out of 50 patients, 19 were diagnosed as neurocysticercosis, 16 as Tuberculomas, 7 as Intracranial Abscess, 4 as metastasis, 3 as primary brain neoplasms, and 1 as Tumefactive Demyelination. Neurocysticercosis was found to be the most common of the pathology diagnosed with Seizures being the most common complaint in patients.Conclusion:The use of MRI along with MR spectroscopy is of vital importance and primary research tool in neuro diagnosis. The most common ring enhancing lesions experienced in developing countries like India is NCC and tuberculomas. Accurate diagnosis and characteristics of these lesions can be achieved by MR spectroscopy on a routine MRI scan by analyzing the quantity and ratio of tissue metabolites.
