MRI of the spinal canal showed a fistula from the sigmoid colon to a presacrally localized abscess, most likely secondary to diverticulitis (fig. 1).
T1-weighted MRI after gadolinium administration. Shown is the presacrally localized abscess (black asterisk) with complete staining of the border. There is diffuse staining of the sacral bone (plus symbols) without involvement of the intervertebral discs, which is suggestive of osteomyelitis. Furthermore, there is diffuse meningeal staining (white arrows) of the conus medullaris and cauda equina. A rectal device (white asterisk) is in situ.
