    MR imaging and angiography of cerebral venous angiomas associated with brain tumors (1992)
    Springer
    Neuroradiology 34 (1992), S. 25-29 
    Details
    ISSN: 1432-1920
    Keywords: Venous angioma ; Brain tumor ; Magnetic resonance imaging ; Cerebral angiography
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary MR study of 6 patients with concurrent venous angioma and brain tumor revealed that in 2 of the 6 cases, the draining vein of the venous angioma was located near to the tumor and was displaced by the tumor. Two of the 6 venous angiomas were too small to visualize prior to contrast enhancement, but could be detected following administration of Gd-DTPA. Angiography was required for definitive diagnosis of the venous angiomas. When a venous angioma is suspected or is detected incidentally, especially when very near a brain tumor, angiography should be considered before performing surgery to avoid surgical complications. Otherwise, ligation of the vein draining the venous angioma may lead to venous infarction.

    Varix occurring with cerebral venous angioma: a case report and review of the literature (1995)
    Springer
    Neuroradiology 37 (1995), S. 29-31 
    Details
    ISSN: 1432-1920
    Keywords: Cerebral varix ; Venous angioma ; Cerebral vascular malformation ; Magnetic resonance imaging

    Topics: Medicine
    Notes: Abstract We report a patient in whom a varix occurred with a venous angioma, a rare combination of cerebral vascular malformations. During our review of the 7 previously reported cases, we discovered that all 8 venous angiomas were relatively large and supratentorial, and that the varices involved the veins draining then.

    Notes: Abstract We report a patient with an epidermoid carcinoma an extremely rare brain tumour, in the right cerebellopontine angle cistern. Contrast enhancement is the most important feature for differential diagnosis of epidermoid carcinomas from atypical benign epidermoid cysts.

    Olivary degeneration after cerebellar or brain stem haemorrhage: MRI (1993)
    Springer
    Neuroradiology 35 (1993), S. 335-338 
    Details
    ISSN: 1432-1920
    Keywords: Olivary degeneration ; Cerebellar haemorrhage ; Brain stem haemorrhage ; Magnetic resonance imaging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Magnetic resonance (MR) images of seven patients with olivary degeneration caused by cerebellar or brain stem haemorrhages were reviewed. In four patients with cerebellar haemorrhage, old haematomas were identified as being located in the dentate nucleus; the contralateral inferior olivary nuclei were hyperintense on proton-density- and T2-weighted images. In two patients with pontine haemorrhages, the old haematomas were in the tegmentum and the ipsilateral inferior olivary nuclei, which were hyperintense. In one case of midbrain haemorrhage, the inferior olivary nuclei were hyperintense bilaterally. The briefest interval from the ictus to MRI was 2 months. Hypertrophic olivary nuclei were observed only at least 4 months after the ictus. Olivary degeneration after cerebellar or brain stem haemorrhage should not be confused with ischaemic, neoplastic, or other primary pathological conditions of the medulla.

    MRI of the brain in chronic carbon monoxide poisoning (1994)
    Springer
    Neuroradiology 36 (1994), S. 399-401 
    Details
    ISSN: 1432-1920
    Keywords: Carbon monoxide poisoning ; Cerebral white matter degeneration ; Cerebral cortical atrophy ; Magnetic resonance imaging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We examined 13 patients with chronic carbon monoxide (CO) poisoning by magnetic resonance imaging (MRI); all of them had been in an explosion in a coal mine 25 years previously. Symmetrical globus pallidus lesions were observed in 12, as was degeneration of the white matter, with focal cortical atrophy. The temporal parietal and occipital lobes were usually affected, the parietooccipital region being the most frequently and extensively damaged. Of the 12 patients with white matter degeneration 7 had definitely asymmetrical cortical and subcortical lesions. There were 6 patients with dilated temporal horns, probably due to atrophy of the hippocampal gyri. A history of CO inhalation and an awareness of the typical distributions of lesions are important for recognition of the effects of CO poisoning, especially when patients are in the chronic stage.

    Cholesterol granuloma in the middle cranial fossa: report of two cases (1995)
    Springer
    Neuroradiology 37 (1995), S. 564-567

    ISSN: 1432-1920
    Keywords: Cholesterol granuloma ; Magnetic resonance imaging ; Middle cranial fossa
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We report two cases of cholesterol granuloma in the middle cranial fossa. On CT the lesions appeared as a nonspecific, nonenhancing soft-tissue mass with bone erosion. On MRI they were seen as areas of high signal intensity surrounded by a low-intensity peripheral zone on both T1- and T2-weighted images. Cholesterol granuloma is thought to occur when pneumatised cellsin the temporal bone become obstructed. Although this lesion usually occurs in the petrous bone, it can extend to the middle cranial fossa. The diagnosis and surgical management are discussed.
