Echinococcus granulosus. Cyst in brain. Photograph of seven year old Italian-born female who fell down five steps and shortly thereafter became unconscious for a few seconds. Vomited for a week. One month later she developed convulsions, headaches, and intermittent drowsiness. A few hours prior to hospitalization, she vomited (nonprojectile), convulsed, complained of pain in the neck and became drowsy. Physical examination showed neck stiffness, hyperactive knee jerks, positive Kernig sign and Babinski reflexes. The patient went into a deep coma with occasional involuntary motions and died two days after admission. At autopsy, a 250 gram , 10 x 5 cm., white-walled cyst bulged through the gray matter of the left cerebrum. Subsequent microscopic examination of the cyst wall revealed typical scolices of Echinococcus granulosus. |

Schistosoma mansoni and Schistosoma haematobium. Hemicolectomy specimen from 40 year old Egyptian male showing large bilharzioma adjacent to the rectosigmoid colon. Several polyps were present in the intestine. The bilharzioma was composed mainly of fibroticc granulomas. About 23,000 S. mansoni eggs and 1,500 S. haematohium eggs per gram of polyp and/or bilharzioma were present. Irregular fibrous masses were present in the colonic serosa as well. Numerous S. mansoni adults were found in the specimen. Surgery was scheduled to provide relief from urinary tract obstruction (right ureter) caused by S. haematobium. The colon was resected because the mass was suspected to be cancer. |

885 |
