In a survey of 46 patients with haemagioblastoma of the CNS (Neurology Dept. University Hamburg, 1950-1980) most (n = 40) were found to have angioblastomas of the cerebellum (Lindau tumors). Of these patients 21 were re-examined in 1983. Headache was the most frequent initial symptom (43%), and within this group one-third (10%-15%) had dizziness, sensorymotor deficits and cerebellar gait disturbances. Signs of elevated intracranial pressure much more often led to the correct diagnosis than dizziness or dystaxia. After the introduction of CCT to the diagnostic procedure the combined evaluation of angiography of the vertebral arteries and CCT always permitted the correct diagnosis. The low neurosurgical mortality rate (13.5%) has decreased to 0% within the last decade. No relapses were found in 21 re-examinations including CCT and EOG compared to a frequency of 9.7% in all 46 cases. Significantly less often than expected from other data we found: signs of possible hereditary influence (0%), multiple tumor localization combined with angiomatosis retinae (0%), polyglobulia (10.8%). Psychopathologically relevant signs (45.6%) were, in all cases, combined with signs of increased intracranial pressure. The results of our re-examination demonstrate that late postoperative deficits as well as possible relapses are earlier and more precisely evaluated by the combined use of clinical examination, CCT and EOG.

A few days after a judo session, an 11-year-old boy presented with an ischemic stroke with dizziness, aphasia and ataxia. CCT scan revealed a left thalamic infarct. Angiography showed a fibromuscular dysplasia (FMD) of the left vertebral artery probably complicated by dissection. Subsequent evolution was favorable. This observation points out the fact that the association of a cervical pain with neurological signs of vertebrobasilar stroke, especially occurring after a cervical trauma or rotatory motion, should alert to the possibility of vertebral-artery dissection. The diagnosis is mainly based on angiographic criteria. Accurate diagnosis has implications for prognosis and probably for acute medical treatment.

The study explored the relationship between health locus of control and anxiety in 90 patients with the chief complaint of dizziness/vertigo. The patients were subjected to a neurological examination, including standardised history, physical examination, electronystagmography with caloric testing and posturography, auditory and visually brainstem-evoked responses, masseter reflex, vertebrobasiliar transcranial Doppler, optional: cranial imaging (CCT/MRI), cardial diagnostic, and a psychiatric-psychodynamic examination (including psychometric tests: STAI-G X2, KKG, SBA-S). The whole group of patients (psychogenic and organic dizziness) had a specific pattern of health locus of control: "double health external" (Type IV-Wallston and Wallston 1982). Patients with psychogenic dizziness showed a higher score of external locus of control (chance) compared with the patients with organic dizziness. High anxiety scores were accompanied by high scores of external locus of control (powerful others and chance) above all in the patients with psychogenic dizziness. Implications for therapy are discussed.
