duodenal obstruction
An
exceptional form of high-grade duodenal obstruction. Preliminary unenhanced acquisition (a..c) showed massively distended stomach (a) and duodenal bulb (+ in b) with fluid and alimentary stasis.

An
exceptional form of high-grade duodenal obstruction. Additionally, subtle unspecific thickening of the perirenal bridging septa (thin arrows) and anterior pararenal fasciae (arrows) was noted.
An
exceptional form of high-grade duodenal obstruction. Arterial-phase acquisition (d,e) showed normal size and enhancement of the pancreas, contracted 2nd and 3rd duodenum (short arrows) without mural thickening. Note thickening of perirenal bridging septa (thin arrows) and anterior pararenal fasciae (arrows).

An
exceptional form of high-grade duodenal obstruction. Similarly, venous phase acquisition did not show abnormal thickening of the duodenal wall (short arrow) or pancreatic enlargement. Note subtle unspecific thickening of the bridging septa (thin arrows) and anterior pararenal fasciae (arrows) was noted.
An
exceptional form of high-grade duodenal obstruction. Venous phase coronal reconstructions (g,h) confirmed overdistended stomach and bulb (+) with fluid; contracted 2nd duodenum (short arrows) without mural thickening or extrinsic masses. Bands (thin arrows) were noted crossing the periduodenal fat.

An
exceptional form of high-grade duodenal obstruction. As seen on delayed phase images (i,j) unspecific symmetric thickening involved the anterior pararenal (arrows) fasciae, to a lesser extent perirenal bridging septa and the right Gerota"s fascia (thin arrows).
An
exceptional form of high-grade duodenal obstruction. Post-surgical CT showed appearance of moderate ascites (*).
An
exceptional form of high-grade duodenal obstruction. Moderate increase of the bilateral thickening of retroperitoneal fasciae (arrows) and progressive infiltration of the left paraaortic retroperitoneal fat (thin arrow) was noted. No significant changes involving duodenum.

An
exceptional form of high-grade duodenal obstruction. Coronal reconstructions (d, detail in e) showed ascites (*), increase of the bilateral thickening of retroperitoneal fasciae (arrows) and progressive infiltration of the left paraaortic retroperitoneal fat.
An
exceptional form of high-grade duodenal obstruction. The 2nd duodenum still appeared contracted with non-thickened walls (short arrow). Increasing infiltration of the periduodenal fat (thin arrows) and development of ascites (*).
