Acute renal vein thrombosis in renal allografts: detection with duplex Doppler US.

abstract：:The authors report an inflammatory fibroid polyp of the colon which simulated a tumor on the air-contrast barium-enema examination. Histological evaluation revealed the inflammatory nature of the polyp. These rare lesions can be radiographically indistinguishable from primary colon carcinoma. ...
