Abstract

Marginal siderosis is recognized in humans as an uncommon clinicopathologic entity characterized by degeneration of neural tissue at the surface of the brain and spinal cord, in association with the accumulation of hemosiderin, and resulting from chronic subarachnoid hemorrhage. The sources of hemorrhage are various and include neoplasms, malformations, cysts, and vasculopathy. Marginal siderosis of the spinal cord due to a myxopapillary ependymoma was diagnosed in a 19-year-old Dutch Warm Blood horse with clinical signs of myelopathy. There is only one previous report of marginal siderosis in the veterinary literature, also in a horse with clinical myelopathy.

摘要

边缘性含铁血黄素沉着症在人类中被认为是一种罕见的临床病理实体，其特征是脑和脊髓表面的神经组织退化，伴有含铁血黄素的积累，由慢性蛛网膜下腔出血引起。出血来源多种多样，包括肿瘤、畸形、囊肿和血管病变。在一匹患有脊髓病临床症状的19岁荷兰温血马中诊断出由黏液乳头型室管膜瘤引起的脊髓边缘性含铁血黄素沉着症。兽医文献中仅有一份关于边缘性含铁血黄素沉着症的报告，也是在一匹患有临床脊髓病的马中。
