FDG-PET positive granuloma of the liver mimicking local recurrence after hepatic resection of colorectal liver metastasis.

There is a burgeoning use of FDG-PET to stage colorectal cancer, in particular for patients with colorectal liver metastases scheduled for surgical resection. However, the accuracy of such imaging technique for recurrent colorectal liver metastasis is unknown. This report described a case of false-positive FDG-PET uptake of the liver mimicking local recurrence after resection of colorectal liver metastasis.
