The human dorsal spinocerebellar tract: myelinated fiber spectrum and fiber density in controls, autosomal dominant spinocerebellar atrophy, Huntington's chorea, radiation myelopathy, and diseases with peripheral sensory nerve involvement.

The human dorsal spinocerebellar tract (DSCT) was evaluated morphometrically in 14 control cases of different age and sex using semithin sections of epon-embedded cross sections from the C3, T5, and T10 segments of the spinal cord. A bimodal fiber spectrum was revealed with one peak at 2-3 microns, and a second, broader peak at about 6-8 microns. Fiber density at C3 was 11,188 fibers/mm2 and at T5, 11,156 fibers/mm2.

The role of continuous-wave Doppler sonography in the diagnosis and management of basilar and vertebral artery occlusions, with special reference to its application during local fibrinolysis ("Vertebrobasilar disease. Time for a new strategy." Louis R. Caplan, 1981).

In general, the prognosis of bilateral vertebral or basilar artery occlusions is very poor. No satisfactory management of this condition is known; in addition, the early diagnosis of severe lesions of the "intradural vertebrobasilar artery" on the basis of clinical signs and symptoms alone is difficult and regularly requires invasive procedures. Continuous-wave Doppler sonography has proved to be of great value in the primary diagnosis of vertebrobasilar thrombosis.

[Computed tomographic brain scanning in the diagnosis of metastatic neoplasms (author's transl)].

Clinical investigations and computed brain scanning were done in 305 patients with primary extracerebral malignant tumours. One third of the patients had cerebral metastases. In most patients with brain metastases extracerebral secondary tumours were known already.

[Lacunar infarcts in computerized tomography. Angiographic findings and differential diagnostic viewpoints].

Eighty-four patients with ischaemic cerebral lesions are described, in whom no lesion of the cortex could be demonstrated by CT. Lacunar lesions of the basal ganglia up to 2 cm. usually fail to show any angiographic findings.

EEG controlled occlusion of the internal carotid artery during angiography.

It became evident in two patients during cerebral angiography that ligation of an internal carotid artery would probably be necessary in the course of a subsequent neurosurgical operation. A balloon catheter was inserted and the internal carotid artery was occluded. A continous EEG recording was made with a Fourier transformed frequency analysis before and during the occlusion; the motor functions of the corresponding side of the body were observed simultaneously on the conscious patient.
