Intracranial Cysticercosis

Author and Disclosure Information

Abstract

THE possibility of infestation of the alimentary tract by the pork tapeworm (Taenia solium) is well recognized, particularly in those areas and countries where poor sanitation and lack of meat inspection exist. Less commonly recognized clinically is the fact that the larval form of Taenia solium, i. e., Cysticercus cellulosae, may also infest the nervous system and its coverings.

Africa and Cruz1 quote Vosgien who reviewed 107 cases of Taenia solium infestation and found that the nervous system was involved in approximately 40 per cent. Dressel2 observed that the brain was affected 72 times in 87 cases, or 82 per cent. Hennenberg,3 in reviewing 1408 autopsies at the Charité in Berlin, reports only 3 cases of cysticerci of the brain having been found. Hare4 of this country relates 2 cases in a large series of autopsies from the Presbyterian Hospital and the Neurological Institute of New York. Arana and Asenjo5 of Chile found 25 cases of brain cysticercosis in a total of 202 intracranial tumors.

While the relative paucity of intracranial infestation in this country offers testimony to the sanitary systems in effect, such infestation is nevertheless possible.

MacArthur6 referred to this condition as a possible cause of epilepsy and Forster7 reported a case of insanity with epilepsy following infestation by Cysticercus cellulosae. Brailsford,8 in 1925, showed that evidence of the parasite could often be obtained by radiography. He intimated that four or five years may elapse before the deposition of calcium in the cysts occurs, if indeed such deposition. . .
