The Incidence and Location of Different Types of Ring Enhancing Lesion of Brain

Abstract

Background: Ring-enhancing lesions are one of the most common types of neuroimaging abnormalities. Many different primary and secondary brain tumors, including glioblastomas, low-grade gliomas, and brain metastases, can also manifest as ring-enhancing lesions. Aim of the study: The objective of this study is to assess the incidence and location of different types of ring enhancing lesion of brain. Methods: This prospective observational study was carried out from January 2012 to December 2013 at the Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, Department of Radiology and Imaging, in collaboration with the Department of Neurosurgery. 56 cases total were randomly chosen for the study population based on clinical and brain CT results. First, all the pertinent information was gathered on a master chart, after which it was arranged using a scientific calculator and the proper statistical formulas. Finally, using MS Office and SPSS programs as necessary, all data were processed, examined, and disseminated. Results: The present study was found that among the ring enhancing lesions of brain patients, highest percentage were in the range of 31-40 years (35.7%). Clinical features of different etiologies headache emerged as the most common complaint that the patients presented. Out of 56 patients, 45 (80.4%) complained of headache. Parietal was observed as the most common site of lesion of 31 (57.1%). Parenthesis indicates percentage out of 21 diagnosed Glioma patients, 20 (95.2%) were single number of lesion and the rest 1 (4.8%) was multiple number of lesion. Perilesional Parenchymal changes were observed 45 (80.3%) patients. Conclusion: The present study was designed and attempted to find out the incidence and location of different types of ring enhancing lesion of brain. This was a single centre study and may limit the ability to reflect the generalized population in our country.
