How is cysticercosis diagnosed?
The diagnosis of cysticercosis can sometimes be difficult, and it may require a combination of tests and imaging studies to make the diagnosis. In Texas, young adults who have immigrated from Mexico, especially from the mountainous regions, that have a new onset seizure should have cysticercosis considered as a possible cause. In general, however, the patient's clinical presentation along with abnormal radiographic imaging results (CT scan of the brain/MRI of the brain) lead to the diagnosis of neurocysticercosis. Blood testing can sometimes be used as an adjunct in making the diagnosis, though it is not always helpful or accurate. These tests are usually performed in more specialized labs. Rarely, a biopsy from affected tissue may be needed to make the diagnosis. Stool studies are sometimes also obtained because they may contain identifiable parasite eggs.
