Technetium-99m DISIDA hepatobiliary tract imaging in pseudotumors of the liver

Tc-99m sulfur colloid images of the liver are frequently falsely reported as tumor or metastases in certain space occupying lesions of the liver. Whether a primary malignancy is known or not, every suspicious space-occupying lesion of the liver should be given the benefit of alternate diagnostic studies before a firm diagnosis of neoplasia is made. This is critical when the decision regarding chemotherapy has to be made. Timely intervention by other diagnostic modalities may obviate the consideration of chemotherapy in cases where there are no liver metastases. The case presented below illustrates the value of hepatobiliary tract imaging in pseudotumors of the liver.
