[The diagnostic value of nuclear magnetic resonance tomography in Sjögen's disease].

Sjögren's syndrome is characterised by xerostomia, xerophthalmia and recurrent parotid swelling. There is a high coincidence with rheumatoid diseases. A variety of clinical and laboratory parameters offers important information for diagnosis, but none of them is specific for this disease. 36 patients with clinical diagnosis of Sjögren's syndrome were examined in a prospective study to evaluate the diagnostic significance of this technique. 34 patients showed an inhomogeneous, nodular pattern in the parotid gland. The signal intensity was very high, especially in the T2-weighted sequences. There was a significant correlation of the radiologic changes with the course of the disease. Four patients with the clinical diagnosis of sialadenosis demonstrated bilateral enlarged glands with a homogeneous signal pattern. Patients with acute purulent parotitis demonstrated enlargement of the gland without an alteration in the signal pattern. Patients with chronic recurrent parotitis and patients with radiogenic sialadenitis showed little inhomogeneous increase of signal intensity. Our results indicate that MRI is presently the radiological method of choice in the evaluation of Sjögren's syndrome.

[Differential diagnosis of cervical space occupying lesion: the parapharyngeal rhabdomyoma].

A case of a parapharyngeal rhabdomyoma is presented. Only about 30 cases of this benign tumor of striated muscles are reported in the literature. Most tumors were located in the lateral cervical region. Histologically a rhabdomyoma must be distinguished from other mesenchymal tumors, especially from granular cell myoblastoma, hibernoma and reticulohistiocytoma. The value of magnetic resonance imaging in the radiological evaluation of parapharyngeal masses is emphasized. Operative resection is generally regarded as the therapy of choice. Local recurrences have been reported in some cases; malignant degeneration is not known.

[The clinical value of magnetic resonance tomography in cystic space-occupying lesions of the mouth floor].

11 patients with cystic lesions of the floor of the mouth were examined by MR imaging. Coronal slices provided an optimal visualisation of the lesions, but axial and sagittal slices added important information with regard to the exact topographic relationship between tumour and muscles. In particular, the mylohyoid muscle could be defined as a key structure. T1-weighted sequences enabled best visualisation of anatomic details, whereas T2-weighted sequences facilitated the primary diagnosis of cystic lesions. The contrast agent Gd-DTPA did not add information of significant diagnostic value. Our results indicate that MRI allows an exact visualisation of location and extent of cystic lesions and their relationship to surrounding muscles. We conclude that MRI is of high value in planning the operative strategy.

[Current diagnosis and therapy of cysts of the mouth floor].

Cystic tumors of the floor of the mouth are relatively rare. Until today the exact localisation of the cysts in relationship to the muscles of the floor of the mouth is established mainly during operation. Therefore the preoperative decision for the optimal surgical approach can be difficult, at least in large space occupying lesions. In the present study the case of a 24-year-old female patient with an extensive dermoid cyst of the floor of the mouth is demonstrated. The preoperative use of magnetic resonance imaging enabled us to determine the exact localisation of the cyst in relationship to the muscular structures of the floor of the mouth. The differential diagnosis of dermoids of the floor of the mouth as well as the adequate therapeutic approach is discussed according to the relevant literature.
