“…While CT readily identifies macroscopic fat, microscopic fat is less identifiable on CT. On the other hand, MRI techniques are highly sensitive in characterizing fat-containing masses, including lipoma. On MRI, a mesenteric lipoma typically demonstrates homogeneous high T1 and intermediate T2 signal intensity and saturates on fat-saturated sequences [4][5][6]. We presented a case with delayed diagnosis due to errors in both clinical and radiological evaluation.…”

Mesenteric lipoma as the cause of intermittent abdominal pain

Mesenteric lipomas are extremely rare lesions with about 50 cases described in the current literature. It is a soft and mobile mass that does not infiltrate surrounding structures, and as a result, it mostly remains asymptomatic. However, in case the tumor reaches a large size, it may cause variable symptoms. Magnetic resonance imaging techniques are highly sensitive in characterizing fat-containing masses, including lipoma. Herein, we present a 58-year-old lady who presented with intermittent abdominal pain due to a mesenteric lipoma, but the diagnosis was delayed because of a series of errors in clinical and radiological evaluations.

“…If there are thicker intervals inside the tumor, nodules, and non-fat-like masses, the proportion of fat in the lesion will decrease. It suggests the diagnosis of liposarcoma (15,16).…”

Primary Omental Lipoma in a Child: A Case Report and Literature Review

BackgroundLipoma is a common benign tumor derived from adipose tissue, with an incidence of nearly 10%. It is the most common mesenchymal tumor throughout the body. However, the pathogenesis of lipoma is not clear yet, and the increased incidence is attributable to obesity, elevated serum cholesterol, diabetes, trauma, radiation, familial predisposition, and chromosome. Primary omental tumor is a rare lipoma occurring in the greater omentum, most of which is reported in the form of clinical case reports. Nevertheless, primary omental tumor is even rarer in children. To date, there have been few reports of clinical cases.Case PresentationWe report a rare case of primary omental lipoma in a 6-year-old boy. After an accidental fall, a CT scan found that he had a tumor in the left upper abdomen. He had no history of abdominal pain, abdominal mass, vomiting, etc. The boy was admitted to the hospital within 3 days, and was diagnosed with an intra-abdominal tumor. After admission, abdominal ultrasound and enhanced CT showed a 71 ×40 ×60 mm mass in the left middle abdomen, which was considered a lipoma. There was no abnormality in tumor markers. Through laparoscopic surgery, intraoperative exploration revealed that the tumor was located in the left mid-upper abdomen, and was yellow, solid, soft, and isolated. The intraoperative diagnosis was an omental lipoma. We used an ultrasonic knife to resect the omentum close to the base of the tumor. The tumor was completely resected, put in a retrieval bag and sealed. Finally, the left and right sides of the umbilical incision were extended to take out the tumor tissue. The child received liquid food 6 h after the operation and was discharged 3 days later. The postoperative pathological diagnosis was an omental lipoma. He was seen at follow-up 3 months after discharge and had no complaints, an abnominal ultrasound showed no tumor recurrence.ConclusionPrimary omental lipoma in children is a rare benign tumor of the omentum. Its etiology and pathology are not clear. US, CT, and MRI can facilitate clinical diagnosis and preoperative evaluation. Laparoscopic surgery is an effective treatment, and the prognosis of children is favorable. This case is beneficial to improve the clinical knowledge of pediatric surgeons about this rare disease.

“…A protracted course of progressive symptoms is often due to the intra-abdominal mass effect and include abdominal pain, distention, early satiety, anorexia, vomiting and constipation [ 5 ]. Acute presentations typically reflect complications, with reports in the literature of torsion and infarction of the lipoma, exacerbation of hernias and intra-abdominal hemorrhage from aberrant vessels [ 2 , 3 , 6 , 7 ].…”

“…However, lipomatous lesions >5 cm or in deep-seated locations have an increased risk of being malignant [ 8 ]. For these reasons, multidisciplinary input and additional imaging with MRI and FDG-PET assists in further characterizing the nature of the lesion, its anatomical relations and guide subsequent management [ 6 , 9 ].…”

“…On CT, a lesion with fat attenuation values is seen, and thin fibrous septations and calcifications may be present [ 4 ]. On MRI, there is homogenous high T1 and intermediate T2 signals consistent with fat, while thin, fibrous intra-lesional septations have low T1 and T2 signal intensities [ 5 , 6 ]. Both CT and MRI allows for better appreciation of localization within the omentum, relationships with adjacent structures and features suspicious for malignancy, including enhancing soft tissue components, thickened and enhancing septations, irregular margins, infiltration into surrounding structures and lymphadenopathy [ 4–6 ].…”

Omental lipoma: a rare cause of a giant intra-abdominal mass

Primary tumors of the omentum, let alone omental lipomas, are rare causes of a large intra-abdominal mass. We report a case of an adult male presenting with an intra-abdominal mass, representative of a giant omental lipoma radiologically, confirmed on histopathology after complete resection at laparotomy. The case highlights the preoperative workup of a suspected omental lipoma, including the utility of various radiological modalities in differentiating from malignant pathologies, and anatomical characterization of the lesion for surgical planning.
