[Lymphoscintigraphic studies of regional lymph vessels in patients with head and neck tumors].

Lymphatic drainage was followed with Tc lymphoscintigraphy. Micrometastases in head and neck cancer cases cannot be detected. The drainage pattern is highly variable and does not allow prognostic conclusions in tumors as demonstrated for the parasternal pathways.

[Pulmonary microlithiasis following iodine lipiodol lymphography?].

Pulmonary fibrosis with marked calcifications in an 83 year old female patient is reported. Following previously inconspicuous thoracic x-ray findings (1975 and 1978) a bipedal oil lymphography was carried out for diagnosis of a systemic malignant lymphoma. The calcifying pulmonary fibrosis was investigated with the help of tomography, computed tomography, xeroradiography and scintigraphy of the lung and the skeletal system as well as magnetic resonance imaging.
