Localized Metastatic Recurrence of HCC following Distal Extremity Trauma: Bone Scintigraphy and Anatomicopathological Correlation

Abstract

Hepatocellular carcinoma (HCC) is the most common type of liver cancer, with a poor median survival when left untreated. Extrahepatic metastases involving musculoskeletal tissues typically present with concomitant nonosseous metastases at the time of diagnosis. A 61-year-old male on 1-year remission, following transarterial chemoembolization of a 2.3-cm hepatic HCC 1 year before, presented with a 2-month history of left wrist pain and swelling after falling on an outstretched hand. Computed tomographic scan revealed diffuse osteolytic lesions localized in left hand and distal forearm, associated with equivocal diffuse activity on bone scan. Subsequent surgical debridement revealed metastatic hepatocellular carcinoma.
