Giant Cavernous Hemangioma of the Liver in a Patient with Autosomal Dominant Polycystic Kidney Disease

Patient: Male, 41-year-old Final Diagnosis: Autosomal dominant polycystic kidney disease Symptoms: Pain Medication: — Clinical Procedure: Computed tomography • ultrasonography Specialty: Gastroenterology and Hepatology • Medicine, General and Internal • Nephrology OBJECTIVE: Congenital defects/diseases 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.
