“…The final diagnosis in our case was attempted by histopathological examination of the specimen. The recurrence rates ranged between 1% and 13.6%, and most recurrences occurred with partial resection or retroperitoneal localization [ 17 ]. After six months of follow-up, there were no signs of recurrence in our case.…”

Lymphangiomas are relatively rare benign congenital tumors of the lymphatic system. They are usually discovered during childhood and typically occur in the neck and axillary regions. Retroperitoneal lymphangiomas are a rare occurrence and represent 1% of all cases. Here, we presented a 70-year-old male who presented with abdominal discomfort and chronic constipation in the last three years. A computerized tomography scan showed a giant abdominal hypodense cystic mass measuring 195 x 145 mm, which laminates the abdominal aorta, the left iliac vessels, and the left ureter. The patient underwent surgical exploration. Due to the giant cystic volume, it was carefully opened, aspirated, and removed. The histopathological examination showed a retroperitoneal lymphangioma. In conclusion, giant retroperitoneal lymphangioma in an adult is a rare occurrence. The primary treatment is complete surgical excision. Histopathological examination is essential for diagnosis confirmation.

“…On CT images, CLMs appear as homogeneous density or heterogeneous density due to the presence of proteinaceous or blood within the lesions and form unilocular or multilocular cystic masses displace intra-abdominal organs and vessels [9].The septa or wall presents mild enhancement on enhanced contrast CT. Sedation is essential for younger children to complete CT examination, and simultaneously, patients would be exposed to radiation. MRI is the most informative imaging examination for evaluating anatomical extension and characterizing lesions, in particular in deep extension like intra-abdominal [11].Filled with uid inside, the lesion presents low signal intensity on T1-weighted images (WI) and high signal intensity on T2-WI with possible internal uid levels [12].Follow-up with MRI provides details to surgeon with post-operative complications and e cacy, which helps to identify the location cysts to be further injected. Compared US and CT, MRI is intuitionistic on intra-cystic complications because it is possible that only part of cysts develop infection or hemorrhage.…”

Background Sclerotherapy is an effective treatment for CLMs of the head and neck. However, Management of intra-abdominal cystic lymphatic malformations(CLMs) remains debates. The purpose of this study was to examine safety and efficacy of laparoscopic assisted sclerotherapy for intra-abdominal CLMs in pediatric patients. Methods We retrospectively reviewed the patients treated with laparoscopic assisted sclerotherapy for intra-abdominal CLMs at a single tertiary medical center between July 2020 and July 2022.The basic information and clinical data of maximal diameter, dose, reduction of lesion’s volume and complications were analyzed. The efficacy was assessed by comparing the pre-operative and post-operative cross-sectional images. Results 7 patients were included in this study and underwent a total of 9 sclerotherapy sessions. 4 patients were symptomatic and majored in abdominal pain. The primary sclerotherapy did not response in better clinical outcome in 2 patients due to intra-cystic hemorrhage and additional procedure were performed. Lesions in 6 patients reduced ≥90% in volume which met the complete response criteria. No further complications were recorded during the follow-up. Conclusions Laparoscopic assisted sclerotherapy is a safe and effective method of managing intra-abdominal CLMs. Laparoscopy could localize the origin of lesions and provides more accuracy and stabilization during the injection procedure.
