@entity2460 of the greater omentum, mimicking XXXX of the small intestine: a case report.

@entity1 @entity1127 @entity5 @entity674 @entity361 @entity652 @entity2460 @entity1086
@entity2460 ( @entity2460 ) is one of the @entity361 , which rarely arises in the abdominal space. We report a very rare case of @entity2460 , mimicking another @entity361 . A 52-year-old Japanese @entity1 was referred to our hospital for further evaluation and treatment of @entity1127 . Contrast-enhanced computed tomography (CT) showed an enhanced nodule within the gallbladder, and incidentally, also showed a well-circumscribed mass adjacent to the small intestine. The mass was depicted as slightly high density in plain CT, and with contrast-enhancement, the mass was partially stained in early phase and the stained area spread heterogeneously in delayed phase. Magnetic resonance imaging showed that the abdominal mass was depicted as slightly high intensity on T2-weighted imaging and low intensity on T1-weighted imaging. With double-balloon endoscopy and capsule endoscopy, we did not find any @entity5 inside the small intestine. These visual findings lead us to diagnose it as @entity674 of the small intestine with extraluminal growth. We planned to resect both the @entity1086 at the same time for pathologic diagnosis and treatment. When the operation was performed, we found a milk-white lobulated @entity5 on the greater omentum and the @entity5 was entirely resected. Microscopically, the @entity1127 was diagnosed as @entity652 , and the omental @entity5 was diagnosed as @entity2460 . It is important to bear in mind that omental SFTs sometimes mimic other @entity361 and should be included in the differential diagnosis of @entity5 not revealed by endoscopy.
