    Description / Table of Contents: Summary Magnetic resonance tomography (MRT) has become the most important method in the workup of infantile cerebral complications after primary sonography. Cerebral MR examination and image interpretation during the infantile period require extensive knowledge of morphological manifestations, their pathophysiological background, and frequency. The choice of imaging parameters and image interpretation is demonstrated in infarctions and hemorrhages of the mature and immature brain. A review of the main differential diagnoses is also given. The relevance of MR spectroscopy and fetal MRI is discussed.
    Notes: Zusammenfassung Zur Abklärung zerebraler Veränderungen bei Neugeborenen hat sich die Magnetresonanztomographie (MRT) als wichtigste weiterführende Methode nach der Sonographie entwickelt. Die Durchführung und Auswertung der MR-Untersuchungen erfordern jedoch eine genaue Kenntnis der morphologischen Manifestationen, des pathophysiologischen Hintergrunds und der Häufigkeit bestimmter zerebraler Komplikationen in diesem Lebensalter. Resümee: Ausgehend von zerebrovaskulären Erkrankungen werden diese Fragen behandelt, wobei sowohl auf die Auswahl der adäquaten Untersuchungsparameter als auch auf die Bildinterpretation und die wichtigsten Differentialdiagnosen eingegangen wird. Die Bedeutung von MR-Spektroskopie und fetaler MRT wird diskutiert.

    Notes: Summary Focal white-matter lesions in the brain have been frequently found in patients with inflammatory bowel disease. These findings have been discussed as a novel extraintestinal manifestation of inflammatory bowel disease. In this case report we delineate the clinical relevance of such lesions by presenting a patient with ulcerative colitis and his associated neurological symptoms. The cerebral lesions were shown by magnetic resonance imaging, whereupon a successful treatment with corticosteroids was initiated.

    Notes: Abstract A pregnant 33-year old woman developed nystagmus and cerebellar ataxia. A tumor in the roof of the fourth ventricle was diagnosed. The tumor was subtotally removed using microneurosurgical techniques. The histopathological diagnosis was choroid plexus papilloma (CPP). Twenty-one months later, the tumor recurred and was reoperated. Histologically the tumor displayed now increased mitotic activity and pleomorphism. Radiation therapy of the neuroaxis was performed. Within 59 months, the CPP recurred 3 more times with neuroradiological evidence of extensive spinal seeding. After several palliative irradiations, including 2 gamma-knife boosts, the patient was referred to chemotherapy. She was treated with CCNU (Lomustin) 100 mg/m2 orally (12 cycles, cumulative dosis 1440 mg/m2). Within 42 months, there was no new local recurrence and spinal seeding showed significant regression. Clinically the patient improved and stabilized, but needs continuous support because of persisting severe gait ataxia. The course of disease in our patient provides evidence for therapeutic efficacy of CCNU in recurrent CPP.
