Biopsy proven neurocysticercosis. The radiological features demonstrated in this case are strongly suggestive to neurocysticercosis: small cystic lesion with a scolex within.
Remember that neurocysticercosis has four recognized stages:
- vesicular - visible parasite with little or no inflammation
- colloidal vesicular - the parasite begins to degenerate (dead) and surrounding edema and inflammation is usually present
- granular nodular - scolex is mineralized, cyst walls thicken and inflammatory process decrease
- nodular calcified - completely mineralized with no inflammation
