Nowadays, in the diagnosis of the extensive endocranial processes, major significance is attributed to the dary changes in the skull that appear also in the X-Rays. Despite some successes in the development of the X-anatomy of the skull and in the study of secondary changes, there are major difficulties in reading the X-rays. This is explained by the fact that the variability in the construction of the various parts of the skul I is more frequent, ially at its base and in the area of the great occipital opening. the literature it can hardly be found how the variations in the shape of the great occipital opening are described IKl peculiarities in the construction of its rear end. fn healthy persons, the semi-axial X-rays of the great occipital opening have an oval shape, a clear and smooth back end, surrounded by a solid bone cylinder that passes toward -.Cmidd\e in the vertically set ridge of the occipital bone. When tumors in the posterior cranial fossa are described, many authors note changes in the great occipital opening a the form of osteoporosis, atrophy, and slinging the sku!J at the posterior end of the opening, with local cleavers aid leveling of the corresponding part of the occipital bone, known as the Bapcin symptom. The anatomical variation of the form of the fora men occipital magnum was axsarnioed on 80 ca\varials. With detail malysis we identified three normal variations of the form of the foramen occipital magnum: the oval (48 cases), the IOUlld (21 cases) and the anomalous form ( l l cases). Also the dorsal end and osseous configuration of the occipital m was examined. The importance of this study is it's prognostic and diagnostic application in the clinical and roentgengratic research. (ireatest difficulties arise in the malignant brainstem process, especially when the invasive process goes to the lliddleofthe back of the great occipital opening. Knowledge of foramen occipital magnum variations is important for surgeons in pereforming many procedures and &may help to avoid clinical coplications, especially, during radiological examination .
