Mesenteric lipoblastoma: case report

Abstract

We present a rare case of mesenteric lipoblastoma in a 16-month-old girl. The US, CT and MRI features of this unusual tumour are described and correlated with the pathology findings. MRI more clearly suggested the presence of fat components in the tumour. In addition, multiplanar MR images demonstrated the anatomical extent better, which was essential for successful complete tumour excision.

Giant mesenteric lipoblastoma in a 4-year-old child

“…Lipoblastoma does not behave aggressively or metastasize, but its growth is rapid and can reach disconcerting proportions [7]. Lipoblastoma located in abdomen (retroperitoneum and mesentery) is uncommon but tends to enlarge (8-23cm in diameter) [4,8]. In our case, the lipoblastoma was giant, which occupied almost the whole abdominal cavity.…”

“…US is often the first modality used for the evaluation of soft tissue and abdominal masses, which usually shows a homogeneous hyperechoic mass [2,8]. CT and magnetic resonance imaging (MRI) could reveal structures and local growth pattern that appear specific of this rare tumor entity.…”

Submandibular Lipoblastoma

“…However, lipoblastomas usually occur within the first 3 years of life, and diagnosis after the age of 5 years is unusual. Moreover, liposarcomas are extremely rare prior to 5 years of age [2,4,7,10]. The age of the patient is therefore the most important distinction, as there is no known imaging finding that can differentiate these two entities.…”

Giant omental lipoblastoma in a 10-month-old infant composing 20% of total body weight

“…Most of these tumors arise from the subcutaneous tissue of extremities but also have been reported in other locations including the neck, scrotum, axilla, and mediastinum. Intraperitoneal lipoblastoma is extremely rare and comprises only 7% of these tumors [3][4][5][6]. Only 7 cases of omental lipoblastoma have been previously reported (Table 1) [1,[7][8][9][10][11][12].…”
