Dr. Bhanusree Konam | Dr. K. Sambasiva Rao | Dr. B. Anuradha ^[3]

Abstract: Ring enhancing lesions are one of the most commonly encountered neuroimaging abnormalities. A wide range of etiologies may present as cerebral multiple ring enhancing lesions. On neuro imaging, these lesions appear as hypodense or isodense mass lesions on non-contrast computed (plain) tomography studies. • After contrast administration, there is a ring or a homogeneous disk like enhancement within the region of hypodensity • MRI’s clinical advantage in early detection of disease is visually demonstrated as unmistakable contrast between gray and white matter and ischaemia / infarct, edema, MS plaques, infection/abscess tumor and hemorrhage. • MR spectroscopy is a potential tool for differential diagnosis between brain abscesses and non-infectious lesions such as primary brain tumor, lymphoma, brain metastasis and tuberculoma. • Magnetic resonance spectroscopy (MRS) provides information about the possible extent and nature of changes on a routine MRI scan by analyzing the presence and / or ratio of tissue metabolites such as NAA, creatine, choline, and lactate etc. .
