It is important to differentiate focal nodular hyperplasia (FNH), a benign condition
of liver most commonly affecting women, from other neoplasm such as hepatic adenoma
and metastasis. The functional reticuloendothelial features of FNH can be demonstrated
by scintigraphy. We present a case of breast cancer in whom fluorodeoxyglucose positron
emission tomography/computerized tomography (CT) showed a homogenous hyperdense lesion
in liver, which on Tc99m sulfur colloid single-photon emission computed tomography/CT
was found to have increased focal tracer uptake suggestive of FNH.
