[Diagnosis of brain abscesses by angiography and nuclear medicine methods].

In most cases, abscesses are formed otogenically or rhinogenically. The clinical symptoms may be uncharacteristic. The diagnosis is made by employing nuclear-medical and angiographic procedures. In 40 patients suspected of having a cerebral abscess, transfemoral cerebral angiography and in 14 cases gammaencephalography or cerebral scintigraphy was carried out. Angiographically, cerebral abscesses mostly appear as avascular growths while nuclear-medical or localised increase in the activity concentration suggests a pathological finding. The symptoms are uncharacteristic and can only be attributed to an abscess process in connection with clinical and paraclinical findings.
