Single small enhancing computed tomographic lesion in Indian children--I: Evolution of current concepts

Single, small (<20 mm) enhancing CT lesions are the commonest cause of focal seizures in Indian children and are also frequently reported from other tropical countries. They often resolve spontaneously on follow-up and have therefore led to controversies regarding their etiology and appropriate management. Initially, these lesions were often considered to be tuberculomas. However, as research progressed over the last two decades, solitary cysticercus granuloma has been found to be the most likely cause for these lesions. In this article we discuss the evolution of current etiological concepts regarding single, small enhancing CT lesions among Indian children, and an approach towards management.
