    Description / Table of Contents: Summary Wernicke’s encephalopathy (WE) is a consequence of vitamin B1 (thiamine) deficiency and in the majority of cases due to alcoholism. We report here the case of a 26-year-old male alcoholic who had stayed helplessly at home for 4 days until hospital admission. Clinical diagnosis was difficult due to major disturbance of consciousness. MRI showed an increase in signal intensity (T2-, FLAIR-weighted) around the third ventricle, the quadrigeminal bodies, the fornices, the mamillary bodies, the floor of the fourth ventricle and around the aqueduct. These findings were indicative of WE although of unusual extent. In this case MRI correlated well with clinical symptomatology. Therapy with thiamine was started immediately and symptoms as well as MRI findings resolved partially. The presented case illustrates the diagnostic usefulness of MRI in WE especially if the patient is of reduced consciousness and clinical investigation is limited.
    Notes: Zusammenfassung Die Wernicke-Enzephalopathie (WE) tritt als Folge eines Vitamin-B1-(Thiamin-)Mangels am häufigsten im Rahmen einer Alkoholabhängigkeit auf. Wir berichten über den Fall eines 26 Jahre alten alkoholabhängigen Mannes, der 4 Tage hilflos in seiner Wohnung zugebracht hatte, bevor er in die Klinik eingewiesen wurde. Die klinische Diagnose war aufgrund einer ausgeprägten Bewußtseinstrübung (Sopor) erschwert. Das MRT zeigte Signalintensitätserhöhungen (T2-, FLAIR-Wichtung) um den dritten Ventrikel, im Thalamus, der Vierhügelplatte, den Fornices, den Corpora mamillaria, am Boden des 4. Ventrikels und periaquaeduktal. Diese Befunde treten typischerweise bei der WE auf, sind jedoch in dieser Ausdehnung selten. In dem hier beschriebenen Fall korrelierte der MRT-Befund gut mit der klinischen Symptomatik. Unter einer Therapie mit Vitamin B1 besserten sich Symptomatik und MRT-Befunde inkomplett. Der vorgestellte Fall verdeutlicht den diagnostischen Nutzen der MRT bei der WE insbesondere bei bewußtseinsgetrübten Patienten, bei denen die Möglichkeiten der differenzierten klinischen Untersuchung eingeschränkt sind.

    Notes: Summary We report a case of moyamoya disease (MMD) associated with arteriovenous malformation (AVM). The 30-year-old female patient presented with left-hemispheric transient ischaemic attacks (TIAs) involving dysphasia and right-sided hemiparesis. CT-scan and lumbar puncture showed no evidence of intracranial haemorrhage. Cerebral angiography revealed typical moyamoya vessels and occlusion of multiple cerebral arteries with consecutive collateral blood supply. Moreover, a left-parietal AVM with a diameter of approximately 2 cm was detected. An extra-intracranial arterial bypass (EIAB) connecting the left superficial temporal artery (STA) with a cortical branch of the left middle cerebral artery (MCA) was performed (STA-MCA anastomosis) and yielded subsequent resolution of the neurological deficit. Nine months post-operatively neurological deficits similar to those of the initial presentation recurred. Repeated angiography suggested comparatively increased AVM blood flow, and successful extirpation of the AVM gradually re-established almost full functional ability. However, deterioration of the neurological condition developed again. We herewith present the first European case of moyamoya disease associated with arteriovenous malformation and report the clinical course under an alternative neurosurgical treatment consisting of STA-MCA anastomosis and delayed extirpation of the AVM.
