    Notes: Summary A case of Whipple's disease is presented manifesting itself predominantly with neurological and mental symptoms but without gastrointestinal complaints. Although the first cranial CT in the fourth year of the disease was normal, the second, 1.5 years later, revealed intensive hypodensity of the white matter and cortical enhancement. CT findings are compared with autopsy results and a review of the pertinent literature is given.

    Notes: Summary A 20-year-old man suffering from Crohn's disease developed coma and generalized seizures following ileocecal resection. During postoperative parenteral feeding he received xylitol in an unusually high concentration. CT examinations a few days before death showed intense hypodensity and swelling of brainstem and basal ganglia and increasing triventricular dilatation. Autopsy revealed, mainly in the brainstem and cerebellum, a destruction of intracerebral, intracerebellar and leptomeningeal vessel walls by birefringent crystals (probably calcium oxalate), an early inflammatory reaction and severe brain edema with final tonsillar herniation. The same crystalloid deposits were found in the kidneys.

    Notes: Summary A calcified chronic subdural hematoma may cover the surface of the cerebral hemispheres to such an extent that one can talk of an “armored brain”. Pathogenesis, clinical course and treatment are discussed based on the computed tomograms of five cases.

    Description / Table of Contents: Zusammenfassung Bei 40 Kindern mit verschiedenen angeborenen Stoffwechselstörungen wurde eine craniale Computertomographie durchgeführt, um Aufschluß über das Ausmaß von cerebralen Veränderungen bei neurodegenerativen Leiden und Speicherkrankheiten zu erhalten. Wir untersuchten 20 Kinder mit verschiedenen Mukopolysaccharidosen, 8 mit Sphingolipidosen, 3 mit Mukolipidosen, 2 mit Oligosaccharidosen, 3 mit Ceroidlipofuszinosen und 4 mit seltenen Leukodystrophien. Die Diagnose wurde bei allen Patienten außer bei dem mit M. Alexander biochemisch oder histologisch gesichert. Hirnatrophie und Dichteminderung der weißen Substanz waren die Hauptbefunde bei der CT. Das Ausmaß der Atrophie war bei Patienten mit Mukopolysaccharidose III, metachromatischer Leukodystrophie und GM1-Gangliosidose altersabhängig. Eine Hypodensität des Marks fand sich bei den Mukopolysaccharidosen I-H, II-B, VI, bei der Mukolipidose II und bei Patienten mit Leukodystrophien. Allerdings sind diese CT-Veränderungen selbst bei Geschwistern inkonstant, wie die Befunde bei 4 Patienten mit Mukopolysaccharidose VI zeigen. Einige Kinder hatten völlig unauffällige Computertomogramme, so daß sich aufgrund eines normalen CT keine der genannten Krankheiten ausschließen läßt. Die gefundenen CT-Veränderungen mit Hirnatrophie und Dichteminderungen der weißen Substanz sind keine spezifischen Befunde der untersuchten Erkrankungen, sie sind jedoch bei den differentialdiagnostischen Überlegungen und zur Verlaufsbestimmung verschiedener Stoffwechselstörungen hilfreich.
    Notes: Summary Inborn errors of metabolism in 40 children have been investigated by computed tomography to obtain data on the degree of cerebral involvement in neurodegenerative and storage disorders: 20 children had various mucopolysaccharidoses, 8 sphingolipidoses, 3 mucolipidoses, 2 oligosaccharidoses, 3 ceroidlipofuscinoses and 4 had various leucodystrophies. Diagnosis in all patients except Alexander's disease was established by biochemical or histological means. The main findings on CT were cerebral atrophy with enlargement of the ventricles and the subarachnoid spaces and hypodensity of the white matter. The degree of cerebral atrophy seemed to develop according to the age of the patients, as could be seen from the patients with mucopolysaccharidosis III, metachromatic leucodystrophy and GM1-gangliosidosis. Hypodensity of the white matter was found in mucopolysaccharidosis I-H, II-B, VI, in mucolipidosis II and in patients with leucodystrophies. On the other hand, there was great variability in these CT findings even in siblings, as seen in four patients with mucopolysaccharidosis VI. Among the series there were several patients who did not show any abnormalities in CT, so that a negative CT did not exclude these disorders, even the leucodystrophies. CT features such as cerebral atrophy or hypodensity were helpful in the evaluation of these disorders, though a diagnosis could not be made by CT alone.
