Frontal Cephalhæmatoma

The term “cephalhæmatoma” is generally used for traumatic lesions of the skull, acquired during the labour or at the early childhood, and causing a subperiosteal hæmorrhage on the outer and inner surface of the cranium. In the later stages, by new formation of bone along the detached periosteum, as well as inside the hæmatoma, a marked thickening and deformity of the skull may develop. The most common localisation of the cephalhæmatoma is the right parietal protuberance; rarer it is seen on the left parietal or on the occipital bone; a frontal localisation seems to be very unusual. X-ray pictures of cephalhæmatomas show characteristic features: a localised thickening of the bone, protrusion of the outer and inner wall of the skull, a dense, spongy, or cystic structure of the lump.
