[Brain sonographic findings in tuberous brain sclerosis. A comparison with roentgenologic images and pathologic-anatomic findings].

Ultrasound examination of a case of tuberous sclerosis is described. The results are compared to plain skull roentgenography, CT and pathological anatomical findings. Apart from the well known advantages of sonography (absence of radiation load, easy and quick practicability of control nearly without strain to the patient) the comparison shows that ultrasound offers a better chance to evaluate the structure of gliomatous masses and their relationship to the adjacent tissues. In connection with the pathological microscopical picture and the results of sonography we drew the conclusion that the paraventricular calcifications in CT so far described are most possibly gliomatous proliferations with densities around 100 HU. Using CT as a diagnostic tool alone it is not possible to distinguish between gliomatous proliferation and calcification in tuberous sclerosis.
