    Emphysematous pyelonephritis related to specific gas-forming Escherichia coli without diabetes mellitus (1999)
    Springer
    Intensive care medicine 25 (1999), S. 628-630

    Notizen: Abstract A 60-year-old-man without a history of diabetes mellitus, or invasive manipulation or obstruction of the urinary tract was admitted for septic shock. Type I emphysematous pyelonephritis was clear in this case: gas within the renal parenchyma extending into the subcapsular region and the perirenal space was present on spiral computerised tomography (CT). Surgical nephrectomy was performed because biochemistry, urography and CT identified a damaged non-functioning left kidney. The outcome was favourable. All urine, blood and nephrectomy specimen cultures were positive for a specific Escherichia coli which produced a high level of gas compared to a reference E. coli strain in the same standard medium, despite the absence of diabetes mellitus. Certain strains of bacteria are able to produce high levels of nitrogen, carbon dioxide and hydrogen and such fermentation in the absence of a high glucose serum level might explain the acute gas-producing bacterial renal infection.

    Rhinoscleroma with orbital extension: CT and MRI (1996)
    Springer
    Neuroradiology 38 (1996), S. 175-178 
    Details
    ISSN: 1432-1920
    Schlagwort(e): Key words Paranasal sinuses ; magnetic resonance imaging ; Paranasal sinuses ; inflammation ; Granuloma ; Orbit ; diseases ; Paranasal sinuses ; diseases
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract We describe the MRI features of a rhinoscleroma with orbital extension. This benign bacterial and granulomatous lesion of the paranasal sinuses gave homogeneous low intensity on T2-weighted images and enhanced with gadolinium. It could simulate a malignant sinonasal tumour or a fungal sinusitis; the diagnosis must be considered in patients from endemic areas.

    Failure to demonstrate a direct caroticocavernous fistula due to arterialisation of the ipsilateral cavernous sinus (1999)
    Springer
    Neuroradiology 41 (1999), S. 67-69

    ISSN: 1432-1920
    Schlagwort(e): Key words Fistula ; caroticocavernous ; Interventional neuroradiology

    Thema: Medizin
    Notizen: Abstract We report a woman in whom a small direct caroticocavernous fistula (DCCF) was revealed after successful transarterial occlusion of a contralateral fistula which drained into both cavernous sinuses. We underline that a second smaller fistula can be masked by a contralateral larger one due to the lack of pressure gradient between the internal carotid artery (ICA) and arterialised blood in the ipsilateral cavernous sinus. We suggest that bilateral ICA angiograms should be performed before and after occlusion of all DCCF.

    Idiopathic granulomatous hypophysitis: clinical and imaging features (1997)
    Springer
    Neuroradiology 39 (1997), S. 7-11

    ISSN: 1432-1920
    Schlagwort(e): Granuloma ; Pituitary ; Computed tomography ; Magnetic resonance imaging
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract Idiopathic pituitary granuloma is a rare disorder similar to lymphocytic adenohypophysitis. Few cases have been reported. We report a new histologically case proven with MRI. The patterns of clinical and radiological presentation and the management of this disorder are discussed. MRI findings suggestive of this condition include an intensely enhancing pituitary mass, associated with dural enhancement. Steroid therapy may be suggested avoiding unnecessary surgery.

    The natural history of familial cerebral cavernomas: a retrospective MRI study of 40 patients (2000)

    Notizen: Abstract Our objective was to determine the natural history and prognostic factors of familial forms of cerebral cavernous malformations (CCM). Cavernomas are one of the most common central nervous system vascular malformations. Familial CCM is increasingly diagnosed, but little is known about its natural history. In a national survey, we analysed clinical and MRI features of 173 patients from 57 unrelated French families. Of these 40 had undergone at least two clinical and MRI examinations. Occurrence of haemorrhage, new lesions, change in signal intensity and size of lesions have been studied by comparison between first and last MRI studies. The CCM were classified according to Zabramski et al. Mean follow-up was 3.2 years (range 0.5–6.5 years). We followed 232 cavernomas (mean 5.9 per patient, range 1–17). Serial MRI demonstrated changes in 28 patients (70 %). Bleeding occurred in 21 lesions (9.1 %) in 14 patients (35 %). The haemorrhagic risk was 2.5 % per lesion-year, higher in type I and brain-stem CCM. We saw 23 new lesions appear in 11 patients (27.5 %), with an incidence of 0.2 lesions per patient year. Signal change was observed in 11 patients (27.5 %), in 14 lesions (6 %), while 9 lesions (3.9 %) in 9 patients (22.5 %) changed significantly in size.
