“…Mesenteric lymphatic malformations (ML) are rare lesions and account for nearly 1%–5% of all lymphatic malformations ( 1 , 2 ). ML are benign vascular lesions almost associated with abnormal embryonic development of the lymphatics but may partly be explained by the bleeding or inflammation in the lymphatic channels ( 3 , 4 ).…”

BackgroundPreoperative complications of mesenteric lymphatic malformations (ML) in children are various and complex. We aim to analyze the incidences and risk factors of three major preoperative complications (hemorrhage of the cyst, infection of the cyst and intestinal volvulus) in ML patients, and explore their influence on the outcomes.MethodsThis retrospective cohort study enrolled ML patients undergoing surgery at Beijing Children's Hospital between June 2016 and June 2022 and classified them according to different preoperative complications, preoperative hemorrhage or infection, and preoperative intestinal volvulus. The groups were examined and compared according to sex, age at admission, presenting symptoms, laboratory examinations, imaging examinations, preoperative treatments, cyst characteristics, surgical details, perioperative clinical data, and follow-up. Logistic regression analysis was performed to identify the independent risk factors for preoperative hemorrhage or infection, and preoperative intestinal volvulus.ResultsOf the 104 enrolled ML patients, 27 (26.0%) had preoperative hemorrhage or infection, and 22 (21.2%) had preoperative intestinal volvulus. Univariate analysis showed that patients with preoperative hemorrhage or infection had a higher rate of ML in the mesocolon (44.4 vs. 23.4%, p < 0.038) and larger cysts (10 vs. 8 cm, p = 0.042) than patients without preoperative hemorrhage or infection. Multivariable logistic regression analysis found that the location (OR, 3.1; 95% CI, 1.1–8.6; p = 0.026) and size of the cyst (≥7.5 cm) (OR, 6.2; 95% CI, 1.6–23.4; p = 0.007) were independent risk factors for preoperative hemorrhage or infection. Preoperative intestinal volvulus was only found in ML at the intestinal mesentery. Further analysis showed that ML in the jejunal mesentery was an independent risk factor for preoperative intestinal volvulus (OR, 3.3; 95% CI, 1.1–10.0; p = 0.027). Patients with preoperative hemorrhage or infection spent more on hospitalization costs than patients without preoperative hemorrhage or infection (3,000 vs. 2,674 dollars, p = 0.038).ConclusionsML patients should be treated as soon as possible after diagnosis. The location and size of the cyst were independent risk factors for preoperative hemorrhage or infection. ML in the jejunal mesentery was an independent risk factor for preoperative intestinal volvulus.

“…Abdominal lymphovascular malformations (ALMs) are thin-walled endothelial channels consisting of lymphatic fluid that can arise associated with low lymphatic flow due to a combination of genetic predisposition and environmental factors. 1 , 2 These malformations are classified according to the International Society for the Study of Vascular Anomalies based on the presence or absence of cysts, circulation pattern of chyle, and specific characteristics of the lymph itself. 3 The incidence of lymphatic malformations is low, ranging from 1:2,000 to 1:16,000, with the most common presenting location being the head and neck, where lymphatic flow is rich.…”

Abdominal lymphovascular malformations (ALMs) are rare cystic masses that can present with nonspecific symptoms. We present a case of a 7-month-old boy who, during an uncomplicated communicating hydrocele repair, was found to have an incidental large, prolapsed mesenteric abdominal lymphovascular malformation. The case serves to highlight the variability in presentation and natural history of ALMs, and the ease with which they can be disguised by more common pathology. We further underscore the importance of individualized therapy with regards to ALMs, emphasized by our course of active surveillance allowing our patient to avoid ionizing radiation and additional surgical intervention.

“…La forma a interessamento mesenterico è però responsabile di 1/20.000 casi di ospedalizzazione in età pediatrica [2,5]. Le masse di più grandi dimensioni vengono di solito identificate durante l'ecografia prenatale già all'inizio del secondo trimestre, ma la maggior parte di esse viene diagnosticata alla nascita o durante i primi due anni di vita del bambino [7]. Sebbene si tenda a identificare nella presenza di connessioni anomale tra la catena linfatica addominale e i vasi venosi mesenterici la causa del rapido accrescimento di tali formazioni, anche condizioni subentranti quali processi infettivi o traumatici potrebbero esserne responsabili.…”

A 3-months baby comes to our emergency department for an abdominal mass of elastic consistency that suddenly appeared for a week and grown exponentially in the last few days. Blood examinations identify a septic state of the child, and the emergency CT recognizes the abdominal mass’s cystic structure. The surgical removal and the histological analysis will confirm the diagnosis of Infected Common Macrocystic Lymphatic Malformation. This case allows us to remember to pediatricians the main features of Cystic Lymphatic Malformations that should always be considered during the differential diagnosis of abdominal masses of sudden onset in an infant.

Abdominal lymphatic malformations

Abstract: In cystic abdominal masses in early childhood or young adults, abdominal LM must be taken into account by the radiologist. Newly defined entities in this spectrum of diseases are central conducting lymphatic anomaly (CCLA) and generalized lymphatic anomaly (GLA).
