腹内淋巴管瘤(Abdominal lympangioma)较罕见,归类于肠系膜和腹膜后腔囊肿。此肿瘤可发生于任何年龄,多数无症状。近年研究报道,腹内淋巴管瘤明显区别于其他肠系膜囊肿,常见于儿童,并且88％病例出现症状。单纯良性间皮瘤和间皮囊肿多发生于中年妇女,且无症状。已有研究证明,儿童和成人腹内淋巴管瘤各有特点,有所不同。 Abdominal lymphangioma (Abdominal lympangioma) is rare and classified as mesenteric and retroperitoneal cysts. This tumor can occur at any age, most asymptomatic. Recent studies have reported that intra-abdominal lymphangioma is distinct from other mesenteric cysts and is common in children, and symptoms occur in 88% of cases. Simple benign mesothelioma and mesothelial cysts occur in middle-aged women and are asymptomatic. Studies have shown that both intra-abdominal lymphangioma in children and adults have their own characteristics and are different.
