[Subarachnoid hemorrhages in primary tumors of the spinal cord].

Spinal subarachnoid hemorrhages and multiple hemorrhages into the tissue of the tumor were diagnosed in 11 (5%) of 221 patients with primary tumors of the spinal cord. The clinical picture was characterized by sudden sharp pain in the spine corresponding in localization to the level of the spinal cord tumor. The stroke-like development of the neurological symptoms alters the classical course of spinal cord tumors considerably and makes it difficult to recognize the pathological process. Vascular disorders predominate in patients with meningiomas of the spinal cord in the upper and middle thoracic segments. The pathogenesis of spinal subarachnoid hemorrhages and hemorrhages into the tumor tissue in primary tumors of the spinal cord is discussed.
