We report four sickle cell anemia patients who have received multiple blood transfusions and have been non-compliant on Desferal chelation therapy. Abdominal ultrasonography demonstrated an echogenic pancreas in all four patients. Magnetic resonance imaging in three patients revealed decreased signal intensity in all sequences in the pancreas and liver. All four patients had marked iron deposition on liver biopsy. To our knowledge, increased echogenicity of the pancreas secondary to hemosiderosis (2 degrees hemochromatosis) in sickle cell patients has not been reported in the radiologic literature.
我们报告了4例镰状细胞贫血患者,他们接受了多次输血且未坚持使用去铁胺螯合疗法。腹部超声检查显示,所有4例患者的胰腺均呈高回声。3例患者的磁共振成像显示,胰腺和肝脏在所有序列中的信号强度均降低。所有4例患者的肝脏活检均显示有明显的铁沉积。据我们所知,镰状细胞病患者因含铁血黄素沉着症(继发性血色素沉着症)导致胰腺回声增强在放射学文献中尚未见报道。
