[Radiographic and scintigraphic studies of cranial bones]

The authors described 9 cases of pathological changes in cranial bones of the type of osteolytic foci of changed osseous structure, post-traumatic lesions and postoperative changes of cranial bones as well as fibrous degeneration of bones which were found during routine scintigraphic investigations of the brain with 99mTc. In 7 cases it was possible to obtain the correct diagnosis after comparing with plain skull films, in 2 cases scintigraphy had to be supplemented with angiography (in one case it was necessary for ruling out paracerebral haematoma in presence of skull fracture, in the other case it was done for demonstrating the vessels supplying frontal bone haemangioma). In none of these cases it was necessary to supplement this investigation with administration of radioisotope markers accumulating selectively in bones.
