Mesenteric cystic lymphangioma: radiologic appearance mimicking cystic teratoma

Lymphangiomas are benign multiloculated cystic tumors. We present radiologic and pathologic findings of a mesenteric lymphangioma containing calcification and mimicking a mesenteric teratoma. This may broaden the differential diagnosis of a cystic mesenteric mass containing calcification.     

Concurrent cystic mediastinal lymphangioma and paratesticular rhabdomyosarcoma

The current report describes a 23-month-old boy with paratesticular rhabdomyosarcoma who was incidentally diagnosed as also having an isolated mediastinal cystic lymphangioma. The association of childhood rhabdomyosarcoma with various congenital anomalies and genetic alterations such as p53 mutations have been well known. However, mediastinal cystic lymphangioma has not been reported among the congenital anomalies diagnosed in rhabdomyosarcoma. Both rhabdomyosarcoma and lymphangioma originate from mesenchymal cells. This association may be coincidental or may point to a common genetic and/or developmental disorder of the mesencymal tissue.     

Intra-abdominal cystic lymphangioma,in a newborn infant

We report a newborn infant presenting with an intra-abdominal cystic lymphangioma, in which necrosis and infection led to an unusual combination of solid and liquid areas observed by ultrasonography.Abbreviations KUB Kidney Ureter Bladder - BUN blood urea nitrogen - MCT median chain triglycerides     

Macrocystic lymphatic lymphangioma (cystic lymphangioma) of the upper extremity: A case report

We report on a case of macrocystic lymphatic malformation of the forearm. A male infant, without any medical history, was followed up in our department since the age of 7 months because of a subcutaneous, soft, painless mass of the left forearm. Ultrasonography and the magnetic reasonance imaging (MRI) were evocative of a macrocystic lymphatic malformation. Five sessions of sclerotherapy led to the reduction of the size of the mass but another axillary tumor appeared afterwards. A surgical excision, unfortunately incomplete, was performed rapidly followed by a recurrence of the macrocystic lymphatic malformation. Macrocystic lymphatic malformations are localized in the neck in 75% and axilla in 20% of the cases. Involvement of the upper extremity and particularly the forearm is very rare. MRI is useful for the diagnosis and the definition of tumor limits. The treatment is usually challenging because of their location and rough delimitation.     

CT differentiation of large abdominal lymphangioma from ascites

Abdominal lymphangiomas are uncommon benign tumors, usually presenting in early childhood as a palpable abdominal mass⁵. Their sonographic and CT appearance has been well described, and usually consists of well-defined, thin-walled cysts which can be unilocular, or multiloculated, and may contain septations. Rarely, these cysts may be large enough to be confused with ascites on physical exam. We present such a case to emphasize the imaging features that may help in the differentiation between ascites and large mesenteric lymphangiomas.     

聚桂醇瘤腔内注射治疗小儿囊性淋巴管瘤

目的 探索聚桂醇瘤腔内注射治疗小儿囊性淋巴管瘤的方法和经验.方法 回顾性分析2010年9月至2014年8月采用聚桂醇瘤腔内注射治疗小儿囊性淋巴管瘤39例的临床资料.39例术前均经彩色超声、CT或MRI检查确诊,治疗时在彩色超声引导下经皮穿刺抽尽囊液后注入药物,对多囊性患儿由深到浅依次抽液后分别注入药物.根据瘤腔位置和大小不同,对眼眶周、口腔、颌下及瘤体容积超过100 ml的18例采用聚桂醇泡沫进行注射,其余21例采用聚桂醇原液进行注射.观察瘤体大小变化、治疗次数和并发症.疗效以瘤体消失,1年后无复发为显效;瘤体缩小50％以上,1年后无增大为有效;瘤体缩小50％以下或治疗后1年内复发为无效.结果 39例治疗1～5次,平均(2.85±0.87)次.显效36例(92.3％),有效2例(5.1％),无效1例(2.6％),总有效率为97.4％(38/39).其中,采用聚桂醇泡沫治疗的次数为(2.72±0.75)次,采用聚桂醇原液治疗的次数为(2.95±0.97)次,两组比较,差异无统计学意义(t=0.26,P＞0.05).有3例第一次注射治疗后当天轻度发热,经物理降温后缓解;5例治疗后局部肿胀,轻微疼痛,观察1～3 d后消失.其余未发现明显并发症.结论 聚桂醇瘤腔内注射治疗小儿囊性淋巴管瘤是一种微创、安全、有效的方法.     

Retro-peritoneal cystic lymphangioma in association with fetal hydantoin syndrome

Antiepileptic drugs are known to be teratogenic. Use of phenytoin during pregnancy can cause various congenital malformations leading to ‘fetal hydantoin syndrome’. One such case reported is unique in the sense that it occurred with retroperitoneal cystic lymphangioma, itself a rare condition. Such an association is not described elsewhere.     

Abdominal cystic lymphangioma in childhood: report of eight cases

Lymphangioma is a common pathology in children, however intra-abdominal cystic lymphangioma is rare. Morphology and clinical symptoms are variable and can be mixed up with other etiology. Ultrasound can make the diagnosis in the majority of the cases. Surgery is the best choice of treatment and prognosis is in general good. Authors present eight cases in a period of fifteen years, all of them treated surgically. Results were good in seven cases. One late death was observed.     

Mediastinal cystic lymphangioma as a cause of hydrops fetalis]

This report is upon a case with fetal hydrops on the base of a paracardiac cystic lymphangioma in the mediastinum. The newborn which had hypoplastic lungs and multiple pneumatothoraces died because of a pulmonary insufficiency. An overview is given about the most common causes of the nonimmune fetal hydrops, and the pathomechanisms are discussed.     

Identification and surgical management of cystic retroperitoneal lymphangioma in children

Retroperitoneal lymphangiomas are rare, benign cystic structures that are best evaluated with computed tomography and ultrasound. Preoperative diagnosis is often difficult, in part because there is little to distinguish them from other cystic masses and because the lesion is often not considered on the differential diagnosis. Surgery may be required as both a diagnostic and therapeutic measure. The cysts may be asymptomatic for years and then present because of compression of surrounding structures or pain. The treatment is as complete surgical excision as is possible. Bowel cleansing should be done preoperatively. The long-term results are excellent when total excision or near-total excision with marsupialization is accomplished.     

Cystic lymphangioma of the abdominal wall in childhood: case report

Intra-abdominal lymphangiomas are rare benign tumours that can cause various symptoms, mainly during childhood. They are diagnosed by ultrasonography, CT scanning or at laparotomy; ultrasonographic examination often shows a voluminous tumoral cystic formation with septa. The location of the cyst may be determined either by ultrasonography alone or by CT scanning. The definitive histological diagnosis is confirmed by immunohistochemical staining techniques. Rarely intra-abdominal lymphangiomas can occur in the abdominal wall. Complete resection is the treatment of choice. The case of a 2-year-old-boy with a large lymphangioma involving the lower half of the abdominal wall is reported. The patient underwent the complete removal of lymphangioma with good cosmetic result.
