ABSTRACT
BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is frequently associated with liver cysts, but an association with giant cavernous liver hemangioma is not mentioned in the literature. CASE REPORT We report the case of a 41-year-old man with ADPKD, secondary arterial hypertension, and stage 4 chronic kidney disease who presented with a 2-week history of persistent pain at the base of the right hemithorax and in the right hypochondrium. An ultrasound examination and a contrast-enhanced computed tomography scan revealed a giant cavernous liver hemangioma. Surgery was intially taken into account (however, twice delayed because of the COVID-19 pandemic) but later refused because it would have left the patient with dangerously few liver parenchyma. CONCLUSIONS To our knowledge, this is the first reported case of ADPKD associated with cavernous liver hemangioma. Vascular endothelial growth factor could be the pathophysiological link between the 2 conditions. Further research may unravel the molecular biology that underlies this possible association, pointing to new therapeutic avenues for ADPKD.
