Introduction: Mesenteric cysts are rare benign lesions. They usually remain asymptomatic and in most cases are incidentally discovered. However, they can reach large dimensions conditioning pain, abdominal distension or sensation of an abdominal mass. The definitive diagnosis is often made during surgery that should involve total removal of the lesion. Knowledge of these lesions is important because of the existence of complications associated with ineffective surgery. This paper reports the surgical treatment of a large mesenteric cyst. Case Report: We report a 20-year-old male with an history of abdominal distension without pain, nausea or vomits. The image examinations revealed a large cystic mass involving the entire abdominopelvic cavity. The patient underwent an exploratory laparotomy and the cyst was excised. The histological examination revealed a serous cyst 33 cm in diameter, without evidence of malignancy. Conclusion: Mesenteric cysts are uncommon lesions that can present asymptomatically or with nonspecific symptoms. Complete resection of the cyst could be challenge but is still the best therapy.
Introduction: Paragangliomas are rare tumors derived from neural crest cells, which are mostly localized in the adrenal medulla. Only 5-10% occur in extra-adrenal localizations. Given the potential of the paraganglioma to secrete catecholamines, some patients present constitutional symptoms such as headaches, tremors and hypertension. However, most patients are asymptomatic. Preoperative diagnosis of paraganglioma in asymptomatic patients is difficult but should be included in the differential diagnosis of solid mesenteric tumors. The gold standard therapy is complete resection, with the need for a long-term followup after surgery. Case Report: Our case study takes a look at a 32-year-old nulliparous woman observed in the emergency room with a severe low abdominal pain. The ultrasonography and computerized tomography revealed a large pelvic tumor with apparent origin in the left ovary. During an exploratory laparotomy, an encapsulated, well vascularized mass was found in the mesentery of the ileum, behind the uterus, conditioning the twisting and consequent bottlenecks of 30 cm of the small intestine. An enterectomy was performed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
