This woman presented at the age of 55 with a history of two-to-three years of persistent
headache over the right side of the head, with occasional epidsodes of vomiting. On one occasion,
she lost consciousness and fell into her soup at a dinner party. Recently she had become
withdrawn, depressed and unable to cope with her housework and, shortly before admission, she
became drowsy and began to drag her right leg. On examination, she was found to have severe
neck stiffness, bilateral ptosis and right-sided hemiplegia; the lesion was demonstrated by brain
scan and, removed with good effect.
