In this study, we evaluated the frequency and prognostic impact of DNMT3A mutations (DNMT3A(mut)) in 1770 younger adult patients with acute myeloid leukemia (AML) in the context of other genetic alterations and the European LeukemiaNet (ELN) classification. DNMT3A(mut) were found in 20.9% of AMLs and were associated with older age (P < .0001), higher white(More)
BACKGROUND To reduce intraoperative bleeding and to facilitate surgery by inducing tumor softening, a preoperative embolization of meningiomas is commonly recommended. PATIENTS AND METHODS We report on our experience with non-resorbable microspheres (Embosphere) in the preoperative endovascular embolization of 17 intracranial meningiomas. After adding(More)
OBJECTIVE Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease) is a rare hamartomatous lesion of the cerebellar cortex. The pathogenesis of the disease is still poorly understood. Lhermitte-Duclos disease was recently considered to be part of a multiple hamartoma-neoplasia syndrome (Cowden disease). We add two further cases to this rare(More)

The patient was a 63-year-old woman with a three years history of intermittent lumbalgia and numbness of the ventral surface of the left thigh. Magnetic resonance imaging detected an intradural(More)
Manifestations of Erdheim-Chester disease in the central nervous system are very rare. Cases with localization in the retroorbital space, hypothalamic area and posterior pituitary as well as intracerebral lesions are known. In our neurosurgical unit, a 51-year-old male patient with a history of hypophyseal insufficiency and visual deficits underwent surgery(More)
Paragangliomas of the CNS are relatively rare. Cases of location in the pineal and pituitary glands, cerebellopontine angle, cauda equina and filum terminale are known. In our neurosurgical unit a 42-year-old male patient with a history of vertigo and a generalized seizure underwent an operation for a fronto-temporal tumour. The histological diagnosis was(More)
