title: Exophytic regenerating nodule of the liver: misleading appearance on iodized-oil CT.
abstract: Iodized-oil CT in a patient with chronic liver disease revealed focal accumulation of iodized oil in an exophytic mass. Single photon emission CT (SPECT) with [99mTc]phytate showed the existence of functioning Kupffer cells, excluding hepatocellular carcinoma. Biopsy revealed a regenerating nodule. Positive iodized-oil CT does not always indicate hepatoma. In such cases, SPECT with [99mTc]phytate will help to make a correct diagnosis.
