    Notizen: Abstract Peliosis is an uncommon condition characterized by multiple blood-filled cavities mostly involving the liver. Although the etiology is unknown the condition may be associated with several disease states and medications. We report the MR findings of peliosis hepatis in a patient with Fanconi anemia who had been treated with anabolic androgenic steroids for 3 years. The MR examination of the upper abdomen was performed on a 0.5 T system. The signal intensity of the right lobe of the liver was diffusely increased in all sequences. Within the enlarged liver, multiple foci of brighter signal were seen involving both right and left lobes. The lesions showed contrast enhancement. A cystic cavity with an enhancing rim was seen representing a haematoma cavity. The spleen was spared the patient died of sepsis and the postmortem examination confirmed the diagnosis of peliosis hepatis.

    Hyperintense basal ganglia lesions on T1-weighted MR images in asymptomatic patients with hepatic dysfunction (1995)

    Thema: Medizin
    Notizen: Abstract Cranial MRI findings in four patients who had hepatic dysfunction, including one with sole hepatic form of Wilson's disease, were reported. The MR examinations revealed bilateral, symmetric hyperintensity in the globus pallidus, subthalamic nuclei and mesencephalon on T1-weighted images with no corresponding abnormality on T2-weighted sequences. The basal ganglia were normal on CT examinations in all patients. None of the patients had the clinical findings of hepatic encephalopathy. The MR findings in our patients did not correlate with the degree or duration of hepatic dysfunction.

    MRI of the facial nerve in idiopathic facial palsy (1996)

    Thema: Medizin
    Notizen: Abstract The purpose of this prospective study was to define the enhancement pattern of the facial nerve in idiopathic facial paralysis (Bell's palsy) on magnetic resonance (MR) imaging with routine doses of gadolinium-DTPA (0.1 mmol/kg). Using 0.5T imager, 24 patients were examined with a mean interval time of 13.7 days between the onset of symptoms and the MR examination. Contralateral asymptomatic facial nerves constituted the control group and five of the normal facial nerves (20.8%) showed enhancement confined to the geniculate ganglion. Hence, contrast enhancement limited to the geniculate ganglion in the abnormal facial nerve (3 of 24) was referred to as equivocal. Not encountered in any of the normal facial nerves, enhancement of other segments alone or associated with geniculate ganglion enhancement was considered to be abnormal and noted in 70.8% of the symptomatic facial nerves. The most frequently enhancing segments were the geniculate ganglion and the distal intracanalicular segment.

    Gadodiamide as an alternative contrast medium in cerebral angiography in a patient with sensitivity to iodinated contrast medium (2000)

    Notizen: Abstract The physical and pharmacological properties of gadolinium enable its chelates to be used as a contrast medium in digital subtraction angiography. We report the use of gadodiamide, a low-osmolar nonionic gadolinium chelate, for selective angiography in a patient with known sensitivity to iodinated contrast medium. No adverse effects were encountered during or after injection. Contrary to a single previous report of the use of these agents in cerebral angiography, contrast in the angiogram was not particularly good, especially in the distal circulation, but the angiogram was diagnostic.

    Notizen: Abstract The most common pattern in subacute sclerosing panencephalitis, is in the cerebral hemisphere white matter on T2-weighted images with or without atrophy. Brain-stem lesions are rare. We report brain-stem involvement in two children with subacute sclerosing panencephalitis. A peculiar pattern, with involvement of the pons with extension to both middle cerebellar peduncles and substantia nigra but sparing the pontine tegmentum, is suggested.

    Notizen: Abstract We present a 4-year-old child who suffered bilateral third nerve palsies secondary to bilateral giant saccular cavernous carotid artery aneurysms. Endovascular treatment was performed by means of direct endosaccular aneurysm occlusion on the right side and parent vessel occlusion on the left, using mechanically detachable coils. No complication occurred during or after the procedure. The bilateral third nerve palsies resolved over 3 months. Follow-up angiography at 1 year is presented.

    Notizen: Abstract We report a partially thrombosed giant of the aneurysm basilar artery with prominent mass effect, diagnosed in an 11 year-old child who presented with neurological deficits due to brain stem compression. After the patent portion of the aneurysm was embolised with Guglielmi detachable coils, remarkable clinical improvement occurred. Angiography demonstrated complete occlusion of the aneurysm and MRI revealed dramatic shrinkage of the aneurysm at 6-month and 1-year follow-up.

    Cerebellar and basal ganglion involvement in Langerhans cell histiocytosis (1999)

    Thema: Medizin
    Notizen: Abstract Langerhans cell histiocytosis (LCH) is a disease of unknown cause characterised by proliferation of histiocytic granulomas in tissues; the primary cerebral manifestation is diabetes insipidus caused by hypothalamic infiltration. We present a patient in whom, except for the absence of high signal on T 1 weighting in the posterior pituitary, consistent with central diabetes insipidus, MRI showed no evidence of hypothalamic involvement by histiocytosis, despite the long duration of the disease. However, there was bilateral, symmetrical involvement of the cerebellum and globus pallidus in addition to a calvarial lesion. High signal in the cerebellar white matter on T 2-weighted images may represent demyelination, gliosis and cell loss, as previously reported on pathologic examination.
