Noch wird vielerorts die Sonographie im Hals-Kopf-Bereich lediglich zur Beurteilung der Schilddrüse oder zur Feststellung arteriosklerotischer Veränderungen an den Hals-Kopf-Gefäßen eingesetzt. Im vorliegenden Beitrag wird ein Überblick der Möglichkeiten und Grenzen der Sonographieuntersuchung der extrathyreoidalen Halsweichteile gegeben. Dabei werden… (More)
Cerebral manifestations of Erdheim-Chester disease are variable, giving a picture like that of multiple sclerosis. White matter lesions are located mainly in cerebellum and pons and lipid granulomas in the meninges. An asymptomatic lesion in the choroid plexus, with prolonged uptake of Gd-DTPA is described for the first time.
A new method for correcting the signal intensity from surface coil (homomorphic filters) was evaluated in 40 examinations. With this filter it is possible to compensate for signal loss when using surface coils for deep tissues and to avoid excessive signals from the surface. The method does not, however, provide any additional information. Properly used,… (More)
Kallmann's syndrome is characterized by hypogonadotropic hypogonadism and anosmia. Postmortem studies have revealed either hypoplasia or aplasia of the rhinencephalon, respectively, in patients with hyposmia and anosmia. This anatomical defect has now been demonstrated in vivo in four patients with Kallmann's syndrome by magnetic resonance imaging.
A rare case of a thymoma metastatic to brain is reported. This tumor was localized intraoperatively with the use of transdural ultrasound imaging, and gross total resection was accomplished. Radiation therapy was administered to both brain and mediastinum. The growth characteristics, classification, and treatment of thymomas are discussed.
In 14 patients with ophthalmoplegia plus Tc-99m hexamethylpropylene amineoxime (HMPAO) brain SPECT imaging was performed. Three patients showed bilateral parieto-occipital hypoperfusions, and two patients had left parietal defects (one with an additional right temporal lesion). Two patients presented with occipital hypoperfusions and one with a distinct… (More)
The existence of chronic trichinosis as a disease entity is still a matter of debate. For 10 years after an outbreak of infection with Trichinella spiralis, we conducted a prospective controlled study of the patients involved. At the termination of this investigation, we undertook clinical, biochemical, serological, immunologic, neuroradiological,… (More)
PURPOSE To evaluate MR patterns in ophthalmoplegia plus and correlate them with clinical symptoms. METHODS MR was performed on a 1.5-T whole-body scanner with T2-weighted gradient-echo and spin-echo images. The retrospective analysis included 19 patients with clinically established diagnoses of ophthalmoplegia plus. RESULTS Two types of cerebral MR… (More)
The radiological and scintigraphic findings in the rare condition of hypertrophic osteoarthropathy (Marie-Bamberger) were followed up for a period of two years. They are described and compared. Skeletal scintigraphy shows the abnormalities in the skeleton at an earlier stage than does radiology and also shows more extensive manifestations. The specific… (More)
Frequently, sonography of the head and neck serves only for assessment of the thyroid and arteriosclerotic lesions of the extracranial vessels. This article gives a review of ultrasound of the remaining cervical structures, particularly spaceoccupying lesions. The differentiation between malignant and benign lymphadenopathy or between intraglandular and… (More)
