Colorectal cancer (CRC) can recur locoregionally or at distant sites. Timely diagnosis
of recurrence is of paramount importance, as radical treatment of the localized disease
can prolong survival. Fluorodeoxyglucose positron emission tomography / computed tomography
(PET / CT) is routinely used in restaging and surveillance of colorectal cancer, as
it can demonstrate recurrent disease with good accuracy. This article illustrates
the spectrum of standard as well as unusual patterns of local recurrence and distant
metastases of colorectal cancer.
