A colourless affect, without neurological symptoms was for decades assumed to be a character attribute of the patient, until the age of 55 years when she developed an akinetic symptom-complex with tremor, but with no rigidity. In the light of the history, the investigations and the operation findings, the symptoms appeared to have a clear aetiological connection with a unilateral, mandarin-sized, fronto-medial meningioma on the inferior edge of the falx. It seemed likely that this had been growing since her youth. The reversible symptoms were judged to be the result of pressure on the mid-brain, with resultant ciuculatory disturbances.
