[A simple radiological technic for the localisation of foramen of Monro in plain skull x-rays (author's transl)]

The foramen of Monro has a remarkable constant anatomical situation. A method using only one basic line (bregma-dorsum sellae) for the stereotactic introduction of a canula in front or within the foramen of Monro for a stereotactic ventriculography is reported. The simplicity and safety of the technique as well as its advantages are emphasized.
