A Diagnostic Dilemma of Hepatocellular Carcinoma on a Background of Thalassemia

Abstract

Purpose: Thalassemia (HbH) is a chronic condition that may have potential complications of liver cirrhosis secondary to iron overload or hepatitis. Iron deposition in the liver can mask the classic imaging findings of hepatocellular carcinoma. We report an interesting case with similar nature with diagnostic dilemma, where multiple imaging modalities were unable to delineate the nature of the liver nature, and the patient was eventually diagnosed with hepatocellular carcinoma, after percutaneous biopsy was performed. Method: A 61-year-old male, with background history of HbH disease and transfusion dependent, presented with an incidental finding of 2 liver nodules on an ultrasound scan after complaints of right hypochondrium pain. A computed tomography (CT) scan diagnosed one nodule as a flash-filling haemangioma but was inconclusive about the other larger nodule. A magnetic resonance imaging (MRI) scan was also inconclusive but gave the differentials of extramedullary haematopoiesis. A sulphur colloid scan did not show uptake, making extramedullary haematopoiesis less likely. Results: A percutaneous biopsy of the indeterminate liver nodule was performed, and the histology showed hepatocellular carcinoma. The patient underwent wedge resection of the hepatocellular carcinoma and recovered well post-operatively. Conclusion: In the event of inconclusive imaging in patients with significant risk factors for hepatocellular carcinoma, a percutaneous biopsy should be performed for definitive diagnosis.
