The ultrasonic appearances of the septa of Bertin in children.

The ultrasonic appearances of the septa of Bertin are described in relation to eight children. These septa may be of varying echogenicity from the remaining cortex and may lead to a misdiagnosis of a true pathological lesion. In our series, two children had an initial suspicion of an abdominal mass; one an intrarenal neoplasm and the other an intrarenal haematoma. It is of importance to recognise this normal variation to avoid misdiagnosis of a pathological mass and to avoid further unnecessary investigation.
