92 PARASITES OF MAN 



one hundred cases have been observed where death had resulted 

 from Cysticerci in the brain. Griesinger alone collected 

 between fifty and sixty such cases. Mental disturbance occa- 

 sioned by the presence of measles in the brain may occur with 

 or without epilepsy. When Griesinger states that " the epi- 

 lepsy from Cysticercus is in all respects like cerebral epilepsy 

 and the psychical disturbances have nothing characteristic 

 about them/' he tacitly admits the impossibility of correct 

 diagnosis during life. 



Since the publication of Griesinger's well-known memoir on 

 Cysticerci of the brain, many similar cases have appeared, and 

 amongst the more recent of these is one by Dr Fredet in which 

 the victim was a^oung man twenty-two years of age. Though 

 apparently in go^d health he fell dead in the street; the 

 fatal result being! due to the presence of a Cysticercus within 

 the pons Varolii. 



Many other cases of earlier date are especially noteworthy. 

 Thus Mr Toynbee recorded a case where an hydatid (which I take 

 to have been the Cysticercus celluloses) situated in the middle cere- 

 bral fossa beneath the dura mater, but in this instance death 

 ensued from other causes. Mr Ottley gives the case of a woman 

 aged forty, where an undoubted Cysticercus in the brain gave rise 

 to distressing fits, convulsions, and death. Then, again, there was 

 Dr Burton's workhouse patient, only twenty years of age, who 

 was found dead in bed, but who at the time of admission 

 merely complained of pain in the head. After death, four 

 hydatids (Cysticerci) were found in the tuber ancillare at the 

 summit of the spinal marrow. M. Bouvier's similar case is 

 also reported in our periodicals. Of instances where Cysti- 

 cerci occupied the cavity of the eye, we have one or two 

 cases by Mackenzie of Glasgow, one by Mr Rose of Swaffham, 

 and others by Windsor, Logan, and Estlin. Amongst the 

 more peculiar cases, I may mention that described by Dr 

 Greenhalgh in the ' Lancet' (1848), where the Cysticercus 

 was lodged within the substance of the lip. Five similar cases 

 are likewise recorded by Heller of Stuttgard. Then there is 

 Dupuytren's case of a Cysticercus ensconced within the great 

 peroneus muscle ; and also Fournier's, where several of these 

 scolices were said to have been found in a boil. The so-called 

 Trachelocampylusj discovered by Fredault in the human brain, 

 was neither more nor less than a common Cysticercus cellulose. 

 It is worthy of remark, as Griesinger has also observed, that
