A 43-year-old man with acute undifferentiated leukemia developed high fever and stomatitis followed by severe abdominal pain after completion of a first course of chemotherapy. A 99mTc-sulfur colloid (SC) scan showed multiple, irregular defects in an enlarged spleen. A 67Ga-citrate scan showed uniform tracer distribution except for a large defect in the upper portion of the spleen. The size of the spleen in the 67Ga-scan was much larger than in the SC scan. At surgery an abscess cavity was found between the spleen and the greater gastric curvature with multiple smaller abscesses on the splenic capsule and throughout the splenic parenchyma. A hematoma was present in the upper pole of the spleen. The disparate splenic size and seemingly discordant distribution patterns of tracer in the 99mTc- and 67Ga-scans were fully explained by histopathological study of the surgically resected spleen.
一名43岁的急性未分化白血病男性患者在完成首个化疗疗程后出现高热、口腔炎，随后出现严重腹痛。99mTc-硫胶体（SC）扫描显示肿大的脾脏有多个不规则缺损。67Ga-柠檬酸盐扫描显示除脾脏上部有一个大的缺损外，示踪剂分布均匀。67Ga扫描中脾脏的大小比SC扫描中的大得多。手术中发现脾脏与胃大弯之间有一个脓肿腔，脾包膜和整个脾实质内有多个较小的脓肿。脾脏上极有一个血肿。对手术切除的脾脏进行组织病理学研究充分解释了99mTc和67Ga扫描中脾脏大小的差异以及示踪剂看似不一致的分布模式。
