A central scar in hepatic focal nodular hyperplasia detected on liver SPECT imaging.
2001
A liver tumor was found incidentally in a 31-year-old woman on abdominal ultrasound. Computed tomographic (CT) scans and magnetic resonance images (MRIs) revealed typical findings of focal nodular hyperplasia. Planar Tc-99m sulfur colloid (SC) images showed a hot lesion, and SPECT images showed a central cold area within a hot lesion. The central cold area observed on the SPECT images corresponded to the central scar seen on CT scans and MRIs. Fine-needle aspiration of this lesion revealed benign-appearing hepatocytes. Follow-up ultrasound examinations for 2 years have shown no change in appearance.
