Background: Ring enhancing brain lesions (REBL) are commonly encountered in the routine diagnostic radiology
practice. Contrast Enhanced Magnetic Resonance Imaging (CEMRI) is the u
diagnosis of REBL. However, the diagnostic accuracy of CEMRI in REBL is still not evaluated extensively. This is
mainly due to the lack of clinical follow up of patients diagnosed with REBL.
the diagnostic accuracy of CEMRI in ring enhancing brain lesions by close follow up of clinical progression and final
diagnosis of the condition and correlating it with the CEMRI findings.

histopathological or serological data from the Medical Records Department of our hospital. The findings were analyzed
using simple statistical methods and param
Based on our study REBLs showed a male predominance. The diagnostic accuracy of CEMRI for ring enhancing brain
lesions is 96.5%. Most common REBL is tuberculoma, followed by neuroc

our study CEMRI has got the greatest diagnostic accuracy in metastasis (98.1%) and least with t
Conclusion: In our study CEMRI shows a good diagnostic accuracy in the diagnosis of REBL. CEMRI
considered as an ideal modality with good accuracy rate, to diagnose ring enhancing brain lesions in the present scenario.
