Supine abdominal X-ray showed narrowed colon and loss of haustration
so-called "lead-pipe colon", which was consistent with repeated mucosal inflammatory process (Fig.
The reason may be that fecal residue became buried in the proximal colon which has deep haustration
, potentially compromising photo precision.
Cut section showed blackish haustration
over nodular area and rest of placenta was normal looking.
Sometimes, at the anteroposterior X-rays can be found some non-specific signs as loss of haustration
and dilation of colon
(34,35) Colonic findings in GVHD include luminal narrowing, wall thickening, and loss of haustration
. Evaluation with MDCT may demonstrate diffuse wall thickening and luminal narrowing of both the small and large bowel.
In the chronic phase, wall thickening, marked loss of haustration
and colonic shortening can also occur.
