Title: Failure to detect extramedullary hematopoiesis during bone-marrow imaging with /sup 111/In or /sup 99m/Tc sulfur colloid

Journal Article · · J. Nucl. Med.; (United States)

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 /sup 111/In chloride and /sup 99m/Tc 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 /sup 111/In or /sup 99m/Tc SC bone-marrow scans to diagnose sites of extramedullary hematopoiesis.
