摘要

腸繫膜靜脈硬化是一種罕見的疾病。此種病症為一緩慢，長期靜脈肌層缺氧，導致靜脈肌肉層硬化繼而鈣化產生，進而靜脈血管肌內膜增生，逐步造成靜脈堵塞。靜脈回流的結果造成缺血性結腸炎。此種罕見病症以往文獻中描述，右側大腸為最常發生之部位，直至目前仍無法確認其發病原因。本文章描述一位成年女性患腸繫膜靜脈硬化之狀況，並就其臨床、放射醫學及病理學之特徵作出討論，以提供將來臨床放射醫學診斷參考之依據。

Mesenteric phlebosclerosis is a rare disease. The pathogenesis of this disorder is inconclusive. It has been proposed that there is a slow, but long-standing hypoxic injury to the venous muscular layer, leading to gradual mummification, sclerosis, and calcification of the venous muscles. This is followed by damage to the reactive hyperplastic myointima in the veins, leading to gradual venous occlusion. Disturbance of venous return results in secondary ischaemic colitis. The right-sided colon is the most often affected bowel segment in previous report. The exact aetiology remains unknown. Thisreport presents the relevant radiological features in a female with mesenteric phlebosclerosis. The clinical and pathological aspects of this entity are also discussed.
