Mesenteric cyst in infancy: presentation and management

Abstract

Mesenteric cysts are documented as a rare entity in pediatric population. They are considered as benign intra-abdominal tumors with an unknown etiology. Symptoms are not specific and knowledge of such condition is essential in order to establish a proper management. We report three pediatrics cases of mesenteric cysts managed between 2000 and 2009 in the pediatric surgery Department of Monastir College Hospital. We described the clinical, radiological and operative findings. Two males and a female were managed (age range: 10 days-5years, mean age: 6,3years). Two patients were presented with an intestinal obstruction. A preoperative diagnosis was made basing on imaging. Thus, abdominal ultrasonography was performed in all of our reported cases and showed a cystic mass in all cases. The cystic nature of the mass, its margins and its extension were better described on tomographic images. The mesenteric cyst was completely and successfully removed in all cases. The histopathological report confirmed the diagnosis and showed a multiloculated cyst with columnar mesothelial lining, without any defined muscular layer or cellular atypia and without any evidence of malignancy. The children were evaluated post-operatively with a mean follow-up of 2 years and a half. No recurrence was noted in our patients during the follow-up period. It is known that clinical features are not specific of such anomaly but once the diagnosis is made, the complete surgical removal of the cyst remains the treatment of choice with excellent outcomes.

A Rare Case of Mesenteric Chylous Cyst in Infant: Case Report and Review of Literature

“…They are often located in the smallbowel mesentery and up to a third of patients have multiple cysts. However, they are most commonly singular, are multiloculated, and rarely contain chylous fluid ( 2 , 3 ). Chylous mesenteric cysts have an estimated incidence of 7.3% of all abdominal cysts ( 7 ).…”

“…Mesenteric cyst (MC) is common in adults while in children and in infants is extremely rare (1)(2)(3). Clinical presentation may range from asymptomatic, a lump or pain in abdomen to intestinal obstruction or hemorrhage (4,5).…”

Minimally Invasive Surgery for Congenital Abdominal Cystic Lesions in Newborns and Infants

“…The sonographic findings in our study demonstrated that a comprehensive analysis of mesenteric cysts via ultrasonography may provide an adequate differential diagnosis although due to the nature of the lesions, before surgical treatment, we advocate more precise radiological examinations. Computed tomography and magnetic resonance imaging can be helpful and essential in order to obtain better feature description of the mass (9). Additional information including the lesion origin, its relationships and its adhesion to visceral organs can be useful if laparoscopic surgery is being considered (10).…”

Exérese de Cisto Mesentérico em Paciente Pediátrico: Relato de Caso / Excision of Mesenteric Cyst in a Pediatric Patient: Case Report

“…Uma vez que uma massa abdominal é suspeita, um exame ultrassonográfico deve ser realizado para uma avaliação radiológica inicial da lesão. Tomografia Computadorizada e Ressonância Magnética podem ser úteis a fim de obter uma resposta descritiva mais detalhada da massa, incluindo, por exemplo, informações como sua origem e relações anatômicas, bem como a sua adesão para os órgãos viscerais próximos, auxiliando no planejamento e na execução de um procedimento cirúrgico quando este for considerado (BELHASSEN et al, 2017). No caso supracitado, o exame tomográfico realizado descreveu múltiplas lesões císticas localizadas no mesentério, à esquerda, na altura do flanco e hipocôndrio, e considerou a possibilidade de natureza linfática.…”
