A patient with postpolycythemic myeloid metaplasia developed an enlarging abdominal mass documented on TCT scanning. To distinguish between lymphoma and extramedullary hematopoiesis, marrow elements were imaged with indium-111 chloride and technetium-99m sulfur colloid. Because the mass failed to accumulate either tracer, a presumptive diagnosis of lymphoma was made and exploratory surgery was performed. The excised mass was found to consist of enlarged lymph nodes containing extramedullary hematopoiesis. Caution should be exercised in the use of In-111 or Tc-99m SC bone-marrow scans to diagnose sites of extramedullary hematopoiesis.
一名真性红细胞增多症后骨髓化生患者经计算机断层扫描发现腹部肿块增大。为鉴别淋巴瘤和髓外造血，用氯化铟-111和锝-99m硫胶体对骨髓成分进行成像。由于肿块未摄取任何一种示踪剂，故初步诊断为淋巴瘤并进行了探查性手术。切除的肿块由含有髓外造血的肿大淋巴结组成。在使用铟-111或锝-99m硫胶体骨髓扫描诊断髓外造血部位时应谨慎。
