Gallium-67 imaging in a patient with malignant thyroid lymphoma that spontaneously regressed after subtotal...

A patient presented with malignant thyroid lymphoma in association with Hashimoto disease. Abnormal, intense Ga-67 accumulation in the thyroid was seen. The patient underwent subtotal gastrectomy for cancer and the malignant thyroid lymphoma regressed spontaneously. Ga-67 accumulation in the thyroid also decreased. The resected stomach was positive for Helicobacter pylori. The patient achieved complete clinical response after H. pylori eradication. Regression of the malignant thyroid lymphoma might be related to H. pylori eradication and the subtotal gastrectomy.
