The greater omentum primary malignant tumors are rare, with less than 50 cases reported. Malignant hemangiopericytomas constitute only four of these cases. The common clinical manifestations of a malignant omental tumor are abdominal mass and pain. We report on a woman 38 years old who came to the hospital's emergency department with a finding consisting of intestinal obstruction (abdominal pain, constipation, abdominal distention, and vomiting), and during a clinical examination a mass was discovered in the lower half of her abdomen. She had been experiencing these symptoms for three days before her arrival. During a clinical examination, a large size, hard mobile mass was discovered in the lower half of her abdomen. The patient underwent an abdominal CT scan which indicated the presence of a sizable, soft tissue mass located within the abdominal and pelvic region, exerting pressure on the small bowel loops, with mild free ascites. Due to the patient's acute abdomen, an exploration laparotomy was performed, revealing a large mass in the omentum measuring 20×20×10 cm and weighing 3 kg. The mass, along with the omentum, was completely removed, and histopathology confirmed a malignant hemangiopericytoma.
大网膜原发性恶性肿瘤罕见，报道的病例不足50例。恶性血管外皮细胞瘤仅占其中4例。恶性网膜肿瘤的常见临床表现为腹部肿块和疼痛。我们报告一例38岁女性，因肠梗阻（腹痛、便秘、腹胀和呕吐）前来医院急诊科，临床检查时在其下腹部发现一个肿块。她在就诊前三天一直有这些症状。临床检查时，在其下腹部发现一个大的、质地硬且可移动的肿块。患者接受了腹部CT扫描，结果显示在腹部和盆腔区域有一个相当大的软组织肿块，对小肠袢施加压力，伴有轻度游离腹水。由于患者急腹症，进行了剖腹探查术，发现大网膜有一个20×20×10 cm大小的肿块，重3 kg。该肿块连同大网膜被完全切除，组织病理学证实为恶性血管外皮细胞瘤。
