3. Detail of infiltrated left fifth nerve, showing: 1, diffuse infiltration with mononuclear cells; 2, perivascular infiltration; 3, strands of relatively unaffected nerve fibers. ] Microscopic appearances in Case 6. Extraocular palsy (focal meningeal syphilis, especially of left fifth nerve). Illustrates exquisite focality of the syphilitic process sometimes found, as well as its unilaterality (giving rise to asymmetrical symptoms and signs). Process in itself probably curable. =GUMMATOUS NEUROSYPHILIS (“gumma of brain”). Autopsy.= =Case 7.= Mrs. Lecompte was a woman of middle age, who, according to the history given by her son, had been entirely well until her final illness, which began approximately two years before admission to Danvers Hospital. The beginning of her trouble seemed to be chiefly headaches, which would last continuously for several days, or more than a week at a time. These headaches lasted throughout the course of the disease. In the morning, on arising, she would feel very dizzy, but this would pass away during the day. She had had a number of spells of unconsciousness, lasting about fifteen minutes. In these attacks she would breathe heavily, there was frothing at the mouth, twitching of the hands, and the eyes would roll about. Her memory failed gradually, her disposition changed and she became very irritable. Vomiting occurred almost every day, and at times was of a projectile character. She became hallucinated; the hallucinations were chiefly of a visual nature. About four months before admission to the hospital, after one of her seizures, the entire right side was found to be completely paralyzed, and she complained that it was numb. At this time, she had difficulty with her speech. In a few days, however, she was able to talk correctly again, and in a week she was back at work, although the right side was weak and awkward. She continued to grow worse, and then began to have spells lasting several days, so that it became necessary to have her placed in a hospital.
