Atypical presentation in the elderly--case report of an acute abdomen.

An elderly woman with an acute abdomen due to a perforated peptic ulcer is discussed to illustrate the problem of atypical presentation of illness in the elderly. The importance of not dismissing non-specific symptoms and signs such as confusion, restlessness, abdominal distention and non-localising abdominal tenderness in the elderly, is highlighted. In addition, the useful radiological features of pneumoperitoneum are described. The need for functional assessment and rehabilitation are emphasised as important components in the practice of geriatric medicine.
