Abdominal Wall Needle Tract Seeding: 15 Years After a Hepatocellular Carcinoma Biopsy

Percutaneous liver biopsy, although considered a safe procedure, can lead to tumoral needle tract seeding. We describe a case of a 65-year-old woman with a history of hepatocellular carcinoma (HCC) who presented with a painless abdominal lump 15 years post-liver biopsy and left hepatectomy. An MRI revealed an abdominal wall mass suggestive of HCC metastasis from needle tract seeding. Surgical removal confirmed a well-differentiated HCC. Distinctive imaging features of HCC in specific clinical settings reduce the need for biopsy, which should be limited to exceptional cases.
