A trefoil appearance of spinal canal (sometimes termed as a cloverleaf spinal canal appearance) is a particular appearance that is of congenital or acquired etiology. This is mainly described in the lumber region and can result in narrowing of the lateral recesess as well as at times involvement of the anteroposterior dimension on the central canal.
