Conclusion
- Classical imaging findings pose no problem for diagnosis of CNS tuberculosis
- Cases of giant or solitary ring enhancing lesions keep on increasing which mimic other infectious and non-infectious pathologies
- Atypical clinical signs and symptoms are not unusual
- High index of clinical suspicion is required for diagnosis
- Profound T2W hypointensity is reliable predictor for giant tuberculomas with intense contrast enhancement, especially in deep locations
- ‘Outer rim excrescence’ sign may contribute in cases of ring and solid enhancing lesions, however it requires further comprehensive study to record as a differentiating feature
