In a recent article in the British Medical Journal Maurice-Williams & Dunwoody (1988) reported two patients with frontal meningiomas who presented initially to psychiatrists. The correct diagnosis was made in one of them after prolonged, perhaps unnecessary, psychiatric treatment. In the other the diagnosis was made at autopsy. In this case psychiatrists were only briefly involved and neurosurgical referral had been made promptly. The authors, who treat these reports as a cautionary tale, conclude by warning psychiatrists to pay special attention to a number of features in the history and examination of psychiatric patients. In particular we are told that suspicion should arise in the presence of gradual non-remitting symptoms such as irritability, memory loss, self-neglect, dysphasia or incontinence in patients without a previous history of psychiatric disease or clear precipitating factors. They also suggest that we pay attention to the views of relatives when they feel the patient suffers from a physical rather than a psychiatric illness, and emphasise that early diagnosis leads to easier surgical removal and better outcome.
