Clinical Analysis of Intraperitoneal Lymphangioma

Large retroperitoneal lymphangioma

Abnormal cystic lymphangioma is a rare, benign tumour of lymphatic origin that often presents with subtle clinical symptoms. A man in his 20s sought medical attention for a progressively tender mass located in the right lower quadrant. Following ultrasound and CT imaging, surgical pathology confirmed the presence of abnormal cystic lymphangioma. This case is noteworthy because of the patient's young age and the retroperitoneal location. An exploratory laparotomy was performed, mitigating the risk of recurrence. In the future, if imaging identifies a cystic mass, consideration of abnormal cystic lymphangioma within the differential diagnosis is imperative. Despite its predominantly subtle symptoms and non-malignant nature, the mass effect by the abnormal cystic lymphangioma can compromise surrounding structures. Overall, clinicians confronted with a cystic mass should adopt a comprehensive diagnostic approach, encompassing abnormal cystic lymphangioma in the differential diagnosis due to its unknown and complex nature.

Review of diagnosis, differential diagnosis, and management of retroperitoneal lymphangioma

Lymphatic malformation (LM) is the currently preferred term for what was previously known as lymphangioma. Retroperitoneal LMs are extremely rare, benign, cystic masses that arise from lymphatic vessels. They can be challenging to diagnose because they resemble other retroperitoneal cystic tumors. The development of treatment strategies for rare diseases, including retroperitoneal LM, requires the acquisition of new knowledge to enhance our understanding of the disease progression. Therefore, we present an update regarding fundamental and advanced issues associated with retroperitoneal LM. This review describes the epidemiology, histopathology, biomedicine, clinical manifestations, radiological features, differential diagnosis, and management of this lesion.

Laparoscopic-assisted excision of a huge polycystic omental lymphangioma in a 3 year old patient presenting with acute abdomen: case report and review

Lymphangioma is a rare benign neoplasm affecting mainly children. In this report we present a complicated case of polycystic omental lymphangioma in a 3 year old female presenting with acute abdomen. The patient underwent a laparoscopic-assisted excision of the lesion and had an excellent postoperative course. We discuss the effectiveness and advantages of this laparoscopic surgical approach in children and elaborate on the current literature.

An acute presentation of pediatric mesenteric lymphangioma: a case report and literature overview

INTRODUCTION

Lymphangioma accounts for 5% of benign pediatric tumors and less than 1% is located in the abdomen. While mesenteric lymphatic malformation or mesenteric lymphangioma (ML), mostly appears asymptomatic in adults, an acute clinical presentation is seen more often in children. Symptoms can mimic obstruction or peritonitis and diagnosis can therefore be challenging. Imaging studies are performed to exclude other causes of obstruction or peritonitis. Diagnosis of ML is always made by histology. Surgery is the treatment of choice and recurrence after complete resection is rare.

CASE REPORT

We describe an acute abdomen in a four-year-old boy caused by a mesenteric lymphatic malformation. Imaging studies at the emergency department were inconclusive and final diagnosis was made by histological examination. Surgical intervention with resection of an ischemic ileal segment was necessary. Complete resection of the ML was not possible without compromising the functional digestive outcome due to diffusely spread lesions in the mesentery of the small bowel. Follow-up with ultrasound was performed.

CONCLUSION

Mesenteric lymphangioma can cause an acute abdomen in children. Complete resection is recommended but might not be feasible without compromising the functional digestive outcome. Alternative treatments should be studied further to treat diffuse and complicated ML.
