A 25-year-old male patient who had a brother with Crohn's disease was referred to our clin,ic with bloody diarrhea and crampy abdominal pain. After a plain erect abdominal X-ray, enteroclysis :was performed, followed by abdominopelvic CT. Be: sides the radiological features of CD, both enteroclysis and CT revealed a big polypoid filling defect in the small intestine. The patient was surgically treated and the histopathology of the specimen revealed a giant fibroid polyp superimposed on CD, an extremely rare complication heretofore unmentioned in the radiology literature. In this report we discuss the role,: of enteroclysis in the diagnosis of complicated cases of long-standing CD. In addition, we also shed light on the importance of both enteroclysis and CT, with their complementary findings, in the radiological diagnosis of rare complicated cases of CD.
