Mesenteric cystic lymphangioma in adult: a case series and review of the literature

the CT scan revealed the presence of multiple ipodense formations in the body and tail of pancreas. Neoplastic markers (AFP, CEA, CA 19-9, CA 15-3, CA125, TPS) were negative. During the hospital stay an abdominal MR was performed. The exam revealed in the retrocecal adipose tissue the presence of a fluid-filled formation with a diameter of 35 mm that appeared indissociable from the cecum for the presence of a tissutal connection (Figure 1 A – B). Other cystic lesions (communicating with pancreatic duct) were present in the whole pancreas and in the right kidney. The patient underwent exploratory surgery: at laparotomy a yellowish ovalar formation with a diameter of 6 cm was found arising from the mesentery of ileum with partial adhesion of the appendix. The lesion had a cystic aspect and was fluid-filled. We performed a total excision of the lesion and appendicectomy. Histopathological examination was consistent with the diagnosis of mesenteric lymphangioma. The patient has been followed-up for 6 months and no recurrence occurred.
