Solitary cysticercus granuloma (SCG) is a common cause of seizures in India as well as several other countries. The granuloma can be a cause of chronic epilepsy. In some cases, the granuloma resolves within a few months, however, it can last for several years in many patients. Calcification is a sign of healed SCG. Enhancement of the lesion after contrast is a sign of active lesion. However, it is not uncommon to find a calcified lesion, which enhances at the same time.
The above MRI shows right frontal calcified lesion (best appreciated on the SWI MRI sequences), which is enhancing with gadolinium contrast. Patient had history of chronic seizures of three years duration.
The only treatment needed in this case is long-term antiepileptic drugs.
