RESUMO
Os osteoblastomas sao tumores osseos benignos raros. Os autores descrevem os aspectos clinicos, o quadro radiologico, angiografico e cintilografico e a tomografia por computacao de 1 doente portador de osteoblastoma de coluna cervical. A remocao cirurgica seguida de artrodese de coluna resultou em alivio da sintomatologia apresentada pelo doente

The radiological findings of syringomyelography are described in a five years old patient who underwent a percutaneous injection of opaque contrast medium (Lipiodol) into the intraspinal syringomyelic cavity. The clinical picture, the usual diagnostic methods and the place of syringomyelography for the diagnosis of syringomielia are discussed.

1. The pressor response to a prolonged carotid occlusion in the rat has two components: an early, fast increase in blood pressure, and a late, slow and sustained hypertension. Since the second component can be blocked by a disconnecting lesion near the medial side of the medial forebrain bundle, the hypothesis that this complex structure is involved in the integration of the late pressor reflex was tested. 2. The medial forebrain bundle was partially or completely destroyed, or a disconnecting lesion was made to interrupt some of its medially running afferents and/or efferents. Incomplete lesion caused a transient suppression of the second component in 4 rats, whereas complete lesion in 5 rats or probable interruption of the medial efferent pathways in 3 rats led to suppression of the late component when the one-minute occlusion was performed within one hour after the lesion. 3. The data show that the medial forebrain bundle plays an important role in the integration of the late component of the pressor response to prolonged carotid occlusion.
