USEFULNESS OF POWER DOPPLER ULTRASONOGRAPHY AND SUPERPARAMAGNETIC IRON OXIDE ENHANCED MAGNETIC RESONANCE IMAGING FOR DIAGNOSIS OF FOCAL NODULAR HYPERPLASIA OF THE LIVER AFTER TREATMENT OF NEUROBLASTOMA

摘要

Focal nodular hyperplasia (FNH) of the liver is rare in children, and it is usually diagnosed through a biopsy of the liver or hepatectomy. The authors report a case of a 10-year-old girl with multiple focal nodular hyperplasia lesions of the liver after the completion of tumor therapy for advanced neumblastoma, and review the usefulness of the combination of power Doppler ultra-sonography (US) and superparamagnetic iron oxide (SPIO) enhanced magnetic resonance imaging (MM) for the diagnosis of FNH without a biopsy of the liver or liepatectomy.
