title: Focal nodular hyperplasia coexistent with hemangioma and multiple cysts of the liver.
abstract: We report here a case of hepatic focal nodular hyperplasia (FNH) associated with hepatic hemangioma and multiple hepatic cysts in a 71-year-old man. He was admitted to our hospital because of body weight loss. Ultrasonography detected multiple cysts. and two tumors in the liver one, 3.5 cm and one, 1.6 cm. Color Doppler ultrasonography showed arterial signals within the large tumor. On dynamic computed tomography, the large tumor was a hypodense lesion which was enhanced during the arterial phase and almost isodense during the delayed phase: the small tumor was also a hypodense lesion, and was enhanced during both the arterial and delayed phases. On magnetic resonance imaging using superparamagnetic iron oxides, the large tumor had decreased signal intensity on the T2-weighted image. On hepatic arteriography, the feeding artery of the large tumor showed a spoke-wheel appearance and that of the small tumor showed a cotton-wool appearance. Ultrasonographically guided fine-needle aspiration biopsy of the large tumor revealed hepatocellular hyperplasia. Finally, we diagnosed the two hepatic tumors as FNH and hemangioma. There was no intracranial lesion. The cause of the patient's emaciation was psychogenic anorexia. To our knowledge, this is the first case report that describes the simultaneous occurrence of these three kinds of hepatic lesions. The pathogenesis of FNH still remains unclear, but this association suggests that FNH may arise because of a vascular anomaly.
