Purpose
CNS tuberculosis is a leading cause of morbidity and mortality in developing countries, caused by Mycobacterium tuberculosis. There is further worsening of the scenario even in developed countries due to increasing numbers of HIV infected patients. Classical presentation of CNS tuberculosis poses no problem for clinicians. However, giant tuberculomas and solitary ring enhancing lesions present as diagnostic challenge because they simulate many infectious and non-infectious medical conditions. The purpose of our scientific exhibit is:
- Highlights the characteristic imaging features of CNS tuberculosis
- Emphasis on giant tuberculomas and solitary ring enhancing lesion in typical and atypical locations which mimic other pathologies
- Introducing a new sign “outer rim excrescence sign’ in ring and/or solid enhancing lesions as a differential point
