Abstract:
Background & Objectives
This study is conducted to evaluate characteristic imaging findings in various ring
enhancing lesions and their characterization.
Objectives
• Differentiate neoplastic vs non neoplastic brain lesions using conventional and
advanced MR imaging techniques.
• Characterization of various ring enhancing lesions with imaging findings.
• Establish a differential diagnosis of the various ring enhancing lesions on conventional
MRI.
• The role of MR spectroscopy in various ring enhancing lesions of brain with a single
voxel proton MR spectroscopy and multiple voxel proton MR spectroscopy.
Methods
Overall 32 patients including 20 males & 12 females were evaluated in this study
conducted at Shri B. M. Patil Medical College, Hospital & Research Center, Vijayapura from
Nov 2018 to April 2020 over a period of 1& ½ years . MRI along with MRS was
performed using PHILIPS ACHIEVA 1.5T & GE SIGNA 1.5T in patients ranging from
ages of 10 months to 76 years.
Results
Out of the 32 patients evaluated 12 cases were tuberculomas, 8 cases of high grade
glioma, 4 metastasis, 4 were NCC, 3 abscesses and 1 case of lymphoma. Seizures are the
commonest presenting complaint seen in 32 cases.

Interpretation & Conclusion
MRI with MRS appears to be the most sensitive modality for characterization of
intracranial ring enhancing lesions (RELs). MRI with help of MRS shows characteristic
imaging findings which helps in differentiating the various RELs. Also it plays a major role
by suggesting the correct diagnosis based on characteristic imaging findings which helps in
patient management.
