Abstract

The presence of a tubercle in the anterior margin of the foramen magnum has been studied in a total of 382 skulls of white adult humans. Its incidence was 1.3%. A radiographic study of this tubercle has been carried out to clarify its cause and internal morphology. The position of this tubercle may be related to traumatic medullar lesions of the occipitovertebral region.
