BACKGROUND
Intestinal lymphangiectasia (IL) is a rare disease characterized by dilation of lymphatic vessels and leakage of lymphatic fluids into the intestinal lumen, causing depletion of lymphocytes, protein, lipids, fat-soluble vitamins, and electrolytes. Hypomagnesemia can occur in IL patients but is seldom discussed.
CASE PRESENTATION
A 30-year-old Tibetan woman who had chronic diarrhea, edema, tetany, and tingling was diagnosed with IL. Prominent hypomagnesemia was noticed. She was treated with a medium-chain triglyceride (MCT) diet and nutrient supplementation with satisfactory results. We also present a systematic review of hypomagnesemia in IL cases from the published literature.
CONCLUSIONS
Hypomagnesemia may be an overlooked complication of IL, thus monitoring serum magnesium concentrations in IL patients is crucial.
背景
肠淋巴管扩张症（IL）是一种罕见的疾病，其特征是淋巴管扩张和淋巴液渗漏到肠腔中，导致淋巴细胞、蛋白质、脂质、脂溶性维生素和电解质流失。低镁血症可发生在 IL 患者中，但很少被讨论。
病例介绍
一位 30 岁的藏族女性，患有慢性腹泻、水肿、抽搐和刺痛，被诊断为 IL。明显的低镁血症。她接受了中链甘油三酯（MCT）饮食和营养补充治疗，效果满意。我们还对已发表文献中 IL 病例的低镁血症进行了系统回顾。
结论
低镁血症可能是 IL 的一个被忽视的并发症，因此监测 IL 患者的血清镁浓度至关重要。
