A 56-year-old man was admitted complaining of throat discomfort and dyspnea. He was given a diagnosis of diffuse large B-cell lymphoma on the basis of findings from tumor biopsy specimens of his left pharynx. MRI tomograms and ultrasonic cardiograms revealed a right atrial tumor causing tricuspid stenosis. Although chemotherapy rendered the cardiac tumor indistinct on MRI and UCG images, gallium-67 scintigraphy still demonstrated abnormal cardiac uptake. After 6 courses of CHOP therapy, sick sinus syndrome with syncope suddenly developed in the patient. A cardiac pacemaker was immediately implanted, and radiotherapy was started. The patient's sinus rhythm returned to normal shortly afterward, and the gallium-67 uptake eventually disappeared. In this case gallium-67 scintigraphy was the only diagnostic procedure capable of detecting evidence of residual disease.
一名56岁男性因咽喉不适和呼吸困难入院。根据其左咽部肿瘤活检标本的检查结果，他被诊断为弥漫性大B细胞淋巴瘤。磁共振成像断层扫描和超声心动图显示右心房肿瘤导致三尖瓣狭窄。尽管化疗使心脏肿瘤在磁共振成像和超声心动图图像上不明显，但镓-67闪烁扫描仍显示心脏摄取异常。在接受6个疗程的CHOP治疗后，患者突然出现伴有晕厥的病态窦房结综合征。立即植入心脏起搏器，并开始放疗。此后不久，患者的窦性心律恢复正常，镓-67摄取最终消失。在这种情况下，镓-67闪烁扫描是唯一能够检测残留疾病证据的诊断方法。
