| Popis: | a cestode that is endemic in much of the developing world. T solium has a complex life cycle in which pigs are the primary intermediate host and humans serve as either definitive or intermediate hosts. Humans become the definitive host of the adult tapeworm by acquiring viable cysticercus larvae from pork meat. In contrast, ingestion of embryonated Taenia eggs (oncospheres) deposited on fecally contaminated food or self-contamination converts a human into the intermediate host [1]. Once the egg is ingested, the eggshell dissolves and the embryo is released. The embryo then penetrates the intestinal wall and is carried by the circulation to the tissue, where it develops into a cystic larva. Cysticerci may be found in any organ, but preferred sites of implantation are the brain, muscles, skin, and eyes. Correct diagnosis of neurocysticercosis is based on laboratory tests and imaging findings. In this essay, we review the many manifestations of neurocysticercosis as shown by CT and MR imaging. |
