A case is reported in which spiral CT was most the contributive imagin
g technique in the diagnosis of a postoperative intrathoracic gastric
herniation. The coronal reformatted spiral CT images demonstrated very
well the intrathoracic stomach located above a normally positioned le
ft hemi-diaphragm. Compared with conventional CT, the multiplanar reco
nstruction capability provided by spiral CT allowed a much better deli
neation of the diaphragm in this case.
