Radionuclide liver-spleen imaging using Tc-99m SC may identify focal defects on routine examinations. Fatty infiltration has generally been described as a diffuse process in the liver that may be manifested on Tc-99m SC liver imaging as a nonhomogeneous pattern of radiopharmaceutical distribution or multiple small defects. This case demonstrates a focal defect on radionuclide imaging, simulating a space-occupying lesion that ultimately proved to be focal fatty infiltration. Although not an uncommon finding on CT, to the authors' knowledge this has not been reported in the nuclear medicine literature to date.
使用锝-99m硫胶体进行放射性核素肝脾显像可能在常规检查中发现局灶性缺损。脂肪浸润通常被描述为肝脏中的弥漫性过程，在锝-99m硫胶体肝脏显像中可能表现为放射性药物分布不均匀或多个小缺损。本病例显示放射性核素显像上有一个局灶性缺损，类似于占位性病变，最终被证实为局灶性脂肪浸润。尽管这在CT上并非罕见发现，但据作者所知，迄今为止核医学文献中尚未有相关报道。
