    Notizen: Abstract We carried out MRI on 43 survivors of childhood cancer after different treatment protocols with or without cranial radiotherapy. They were free of disease, therapy having been discontinued 2–20 years earlier. Treatment had been for various malignancies, excluding brain tumours; 27 had received cranial irradiation for acute lymphoblastic leukaemia (ALL) or lymphoma. Two asymptomatic young women treated for ALL had falx meningiomas. White matter changes, low intensity foci (representing calcification or old haemorrhage) and heterogeneous intensity focic old haemorrhages) were seen only in patients who had undergone radiotherapy. Because of the possibility of benign, potentially curable brain tumours occurring after cranial irradiation, it may be wise to carry out occasional cranial imaging in the follow-up of these patients. No routine imaging follow-up is needed after chemotherapy alone.

    Notizen: Abstract We describe a rare entity, superficial siderosis of the central nervous system, due to multiple small episodes of subarachnoid haemorrhage from any source. Nonspecific neurological findings are associated with deposition of iron-containing pigments in the leptomeninges and superficial layers of the cortex. T2-weighted magnetic resonance imaging demonstrates characteristic low signal in the meninges.

    Notizen: Abstract Gliomatosis cerebri, a rare condition, requires clinical, radiological and pathological correlation for diagnosis. Mental and personality changes are the most common presenting symptoms with or without focal neurological signs. The widespread nature of the disease is revealed by CT or MRI. The shape of the brain may be maintained and pathological gross examination may be unremarkable or show hypertrophy without evident tumour. Microscopic examination reveals infiltration of the brain by variably differentiated neoplastic glial cells. We present a patient with gliomatosis cerebri in whom we experienced difficulties with diagnosis. The literature is reviewed and the diagnostic features summarised.

    Notizen: Abstract We present a patient with multiple brain abscesses caused by Nocardia asteroides. On T2-weighted MRI, multiple concentric rims were seen in the abscess, which could be a finding specific for infection. The rims may be due to organization of the necrotic debris and phagocytoses by macrophages in the capsule.

    Notizen: Abstract Cranial MRI was used to study treatment-related changes in children undergoing therapy for acute lymphoblastic leukaemia (ALL) or lymphoma. Nineteen children (18 with ALL, 1 with lymphoma) underwent MRI at the beginning of treatment and at intervals during it, to a total of 105 imaging studies and a minimum of 3 per case. Nine patients had finished all therapy, all received consolidation treatment. No patient had central nervous system (CNS) leukaemia at diagnosis or developed a CNS relapse. Mild treatment-related white matter changes were observed in only 2 patients after consolidation therapy with three 5 g/m2 pulses of intravenous methotrexate. Transient enlargement of the ventricles and cortical sulci was observed in 13 patients, always temporally related to steroid treatment. These preliminary data suggest that treatment-related white matter changes are rare and no routine MRI follow-up is needed during treatment in asymptomatic children after a baseline assessment.
