Digital 320-slice volume computed tomography scanning in the diagnosis of gastrointestinal lipoma

Background: to explore the diagnostic value of digital 320-slice volume computed tomography (ct) scanning in gastrointestinal lipoma. materials and methods: the clinical data and ct features of 21 gastrointestinal lipoma cases confirmed by pathology were analyzed retrospectively. the tumor location, size, density, and clinical manifestations were summarized. results: among 21 patients, nine, four, three, and three cases occurred in the duodenum, descending colon, stomach, and ascending colon, respectively; one case each occurred in the jejunum and sigmoid colon. tumors located in the duodenum were asymptomatic, while those located in the colon presented with abdominal pain and diarrhea. ct images demonstrated round, oval, and short intestinal fat-like density masses in the gastrointestinal tract with varying sizes. the ct value was in the range of -80 to -120 hu. routine enhanced scans revealed no enhancements. three cases were accompanied by intussusception. pathological examination showed prominent fibrovascular septa. conclusion: digital 320-slice volume ct scans have advantages over other modalities in the diagnosis of gastrointestinal lipoma and may help evaluate the tumor and surrounding tissues, supporting clinical practice.
