A diagnosis of Sjögren's syndrome or rheumatoid arthritis was made in five women in whom multiple myeloma was first suspected. All had mild symptoms of sicca or arthritis, positive tests for rheumatoid factor or antinuclear antibody, and markedly increased IgG immunoglobulins. A connective tissue disorder may produce the characteristic electrophoretic pattern of multiple myeloma.
During angiographic placement of an intra-arterial hepatic catheter, a spasm was encountered in the proper hepatic artery. Subsequent angiography, however, revealed normal arteries. Tc-99m MAA intra-arterial infusion was then performed which showed a hepatic artery spasm. Twenty-four hours after the initial hepatic arterial spasm, a repeat injection of Tc-99m MAA revealed that the spasm was no longer present and, therefore, that intra-arterial chemotherapy could be administered.
In two patients with inferior vena caval obstruction, radionuclide venography using 99mTc-macroaggregated albumin demonstrated diffuse radioactivity in the liver, indicating portosystemic shunts. Follow-up venography after anticoagulation therapy showed disappearance of the hepatic activity in one patient.
