[Evaluation of RI scintiscanning to parotid gland tumors].

Department of Otolaryngology, Kobe City General Hospital, Kobe.
We retrospectively evaluated preoperative radioisotope (RI) scintiscans in 275 patients (283 glands) with parotid tumors who undergoing surgery between 1987 and 2000. Technetium-99m-pertechnetate (Tc) scintigraphy was conducted on 201 glands. Oncocytoma and Warthin's tumor showed a high positive rate.

Department of Radiology, Yamanashi Medical University, Japan.
Unlabelled: We investigated and compared findings on combined 99mTc pertechnetate-201Tl with those of [99mTc]pertechnetate-67Ga scintiscans to elucidate the advantages of 201Tl in detecting various salivary glands disorders.
Methods: We studied 23 patients: 6 had sialadenitis, 12 had benign tumors and 5 had malignant tumors. All but four patients had undergone [99mTc]pertechnetate (before and after lemon stimulation), 201Tl (early and delayed) and 67Ga imaging.
Gallium-67 scintiscan in the diagnosis of primary splenic non-Hodgkin's lymphoma after the treatment of Hodgkin's disease.

Division of Nuclear Medicine, Jefferson Medical College, Thomas Jefferson University Hospital, Philadelphia, Pennsylvania 19107.
A rare primary non-Hodgkin's lymphoma (diffuse large cell) of the spleen developed in a 72-yr-old man who had successful radiotherapy to the right inguinal region for Hodgkin's disease 23 yr ago. Radiologic findings, particularly the 67Ga scintigraphy finding, were very useful in leading to the correct diagnosis of malignant splenic lymphoma, in this case, preoperatively.

Melanoma is characterized by a tendency to metastasize widely throughout the body and its relative affinity for gallium-67. Because of the ability of this nuclide to image tumor sites in numerous organ systems, it has been used to detect metastases in patients with malignant melanoma. The effectiveness of this technique, however, has been controversial.

Noncaseating granulomas were recognized with significantly greater frequency in stage 2 (80 percent; 8/10 cases) than in stage 1 (43 percent; 6/14 cases). Alveolitis showed little relation to the roentgenographic stage.
