“…The regression rates of lymphangiomas are reported to range from 1.6% to 16.0%, and these have been reported only mostly in lymphangiomas of the head and neck 18. While cases of spontaneous regression of intra-abdominal lymphangiomas have been described before, these are uncommon occurrences, with complete regression being relatively rare 19–21. Regression of lymphangiomas may also occur after an infection 22.…”

Spontaneous partial regression of a microcystic jejunal mesenteric lymphangioma and a proposed management algorithm

et al. 2019

Mesenteric lymphangiomas are relatively rare, with clinical symptoms ranging from an asymptomatic presentation to an acute abdomen. The natural history and biological behaviour of this entity can range from slow indolent lesions to aggressive tumours with a risk of malignant transformation. Spontaneous regression of a mesenteric lymphangioma is rare. We herein report a case of a jejunal mesenteric lymphangioma that was initially detected incidentally in an asymptomatic patient with a subsequent sudden increase in size with resulting surrounding mass effect after 9 months and a spontaneous partial regression at surgical resection. Our case is the first reported case which outlines a period in the natural history and evolution of microcystic mesenteric lymphangioma, illustrating the sudden enlargement likely attributable to spontaneous and self-limiting haemorrhage and subsequent partial regression at surgical resection. We thenceforth propose a possible management algorithm for adult patients with mesenteric lymphangiomas.
