RESUMO
Moyamoya disease is a chronic and unusual cerebrovascular disorder characterized by progressive stenosis and occlusion of the distal portions of internal carotid arteries and its main branches within the circle of Willis. Posterior circulation (vertebral and basilar arteries) may also be affected; however, this presentation is uncommon. As well as stenosis of the terminal portion of intracranial arteries, it is seen the development of a network of collateral vessels abnormally dilated at the base of the brain with an aspect of a "puff of smoke," whose term in Japanese is described as "moyamoya." The present study aims to report two consecutive cases of patients who presented to our service with different clinical manifestations. Further investigation with digital subtraction angiography showed a moyamoya pattern.

We describe a case of a patient with a thoracic spinal mixed capillary/ cavernous haemangioma, who was operated for decompression. The literature regarding spinal haemangiomas is reviewed and the symptomatotogy, neuro-radiotogy, pathology, management and prognosis of these lesions are discussed. The need to include cavernomas in the differential diagnosis of various spinal conditions is emphasized

The spinal cord can be involved in a variety of disease processes. These can be congenital or acquired. An acute onset of symptoms usually allows a defined set of causes to be considered including trauma, ruptured vascular anomalies, demyelination, and myelitis. Intramedullary cavernous hemangioma of the spinal cord is a congenital or acquired vascular malformation, and one of the rare causes of hematomyelia. We present such a case, and discuss the symptoms, diagnosis, and suggested best treatment options based on a review of present day literature
