A 73-year-old male was admitted to our institution with complaints of @entity1209 . Plain abdominal computed tomography (CT) suggested intussusception in the jejunum. Enhanced abdominal CT revealed the 'target-like' sign and ultrasonography revealed the 'multiple concentric ring' sign; therefore, a diagnosis of @entity3473 was made. The small @entity1321 and cause of the intussusception were not evident. The @entity1 was treated conservatively with fasting and transfusion therapy to prevent @entity1321 . However, with no spontaneous resolution of intussusception, surgical treatment was decided. The operative findings revealed a @entity5 about 30  cm from the Treiz ligament, and the jejunum including the @entity5 with a 5  cm margin were partially resected. The resected @entity5 was a 35  *  50  mm soft mass spreading laterally with nodules. The pathological examinations revealed @entity420 in the @entity652 . Intussusception is rare in adults compared to @entity1 . About 45  % of cases of intussusception in adults are due to small @entity4056 such as @entity706 , but a @entity420 with @entity652 is a rare cause of intussusception. We present a rare case of jejunal @entity420 in @entity652 presenting with @entity3473 .
