Welcome to Health care magic. 1. The features in the contrast enhanced computer tomography reveals granulomatous lesion with surrounding oedema - possible cause is neurocysticercosis. 2.Infection which leads to extra-intestinal disease (including neurocysticercosis) usually occurs as a result of eating food or drinking water contaminated by human feces containing T. solium eggs. This is distinct from the normal life cycle in which the undercooked pork is eaten and the larval cysts contained within mature into adult intestinal tape worm. 3.Different stages are - 1. Vesicular 2. Colloidal vesicular - earlier with treatment and the cyst fluid becomes turbid. As the membrane becomes leaky oedema surrounds the cyst. This is the most symptomatic stage. 3.Granular nodular - oedema decreases as the cyst retracts further; enhancement persists. 4.Nodular calcified - end-stage quiescent calcified cyst remnant; no oedema. 4.Granuloma is a calcified structure from a dead parasite. Similar features are seen in case of tubercular cases after infection. 5.Treatment include - anti parasitic treatment. Hope it helps you. Wish you a good health. Anything to ask ? do not hesitate. Thank you.
