  • Title: Splenic uptake of both technetium-99m diphosphonate and technetium-99m sulfur colloid in sickle cell beta (0) thalassemia.
    Author: Heck LL, Brittin GM.
    Journal: Clin Nucl Med; 1989 Aug; 14(8):557-63. PubMed ID: 2805534.
    Abstract:
    A 19-year-old black woman with sickle cell beta(0) thalassemia had experienced more than 100 hospital admissions for sickle cell crisis and aseptic necrosis of both femoral heads. Her spleen was enlarged threefold and accumulated both radiocolloid and bone-seeking agent on two occasions, demonstrating an exception to the rule in sickle cell anemia that spleens that take up bone-seeking agents demonstrate functional asplenia. In the context of fever, left upper quadrant pain, and splenomegaly, the pattern of calcification in the patient's spleen as revealed in ultrasound and CT studies suggested possible abscess and led to unnecessary splenectomy. The nuclear medicine studies did not support this diagnosis. Nuclear medicine physicians should not be misled by splenic findings of sickle cell thalassemia (and possibly of other heterozygous sickle cell disorders) that differ from those of the more familiar homozygous sickle cell anemia.
