[The pulmodiaphragmal ligament. An often misinterpreted normal variant].
In some cases the pulmonary ligament extends caudally to the diaphragm, where it blends with the parietal pleura. This anatomical variant is named the pulmodiafragmal ligament. In chest X-ray it gives rise to spikes and unsharp areas in the central part of the diaphragm in the lateral view. The article describes the pulmodiafragmal ligament and its significance by the interpretation of chest X-ray in normal and pathologic states.
