Intra-abdominal lymphangioma in a newborn

Prenatal Sonographic Diagnosis of Abdominal Mesenteric Lymphangioma

“…Although they may displace adjacent structures, obstruction of the bowel, vessels, or ureters is uncommon. 5 Our patient had abdominal distension and obstipation as a result of obstruction and compression of the small intestine. In a series of prenatal sonographically diagnosed cases from the literature, 4 of 7 patients had retroperitoneal lymphangiomas of the abdomen extending into the thigh or buttock, which was not present in our patient.…”

“…The differential diagnosis of large intraabdominal or pelvic cystic masses in childhood includes bowel obstruction, bowel duplication cysts, mesenteric cysts, and, in girls, ovarian serous cysts, cystadenomas, and cystic teratomas. 5 The early diagnosis of abdominal lymphangiomas is important because they have the potential to cause complications such as intestinal ischemia by their mass effect. Although they may displace adjacent structures, obstruction of the bowel, vessels, or ureters is uncommon.…”

Recurrent Retroperitoneal Cystic Lymphangioma

“…However, it is currently accepted that lymphatic vessel tumors are developmental malformations rather than being real tumors 7. Abnormal lymphatic channels dilate in an attempt to produce uni- or multi-locular cystic masses.…”

“…Smaller lesions such as traumatic hematomas and urinomas can be clinically diagnosed. In enteric duplications, US can generally demonstrate the significant muscular and mucosal layers and the hyperechogenicity at the periphery of the mass 7. Abdominal lymphangiomas are often discussed in conjunction with mesenteric cysts, but lymphangioma presents earlier in life 13.…”

A pitfall in diagnosing fetal abdominal lymphangioma: A report of two cases

“…Fetal abdominal lymphangioma is an uncommon congenital anomaly detected incidentally during the prenatal period by routine fetal ultrasound. While the majority of lesions appear as anechoic and multilocular cysts with thick or subdivided septation, some cases do not conform to these typical features. We encountered two cases of fetal abdominal lymphangioma that were misleading because of atypical ultrasound findings.…”
