Abstract
Background: Tumor implantation in the chest wall after hepatocellular carcinoma biopsy is documented. This study was conducted to evaluate the Sonographic pictures of chest-wall-implanted hepatocellular carcinoma (HCC). Materials and Methods: From 1983 to 1995, nine patients with hepatocellular carcinoma who bad tissue-proven chest wall tumor implantation after biopsy or aspiration were studied. Results: The time between the puncture biopsy and the detection of chest-wall-implanted tumors ranged from 12 to 56 months. The Sonographic pictures of the nine patients revealed that the tumor size ranged from 1.5 cm to 6.0 cm. The echo patterns showed hypoechoic tumor in six patients, isoechoic tumor in two and isoechoic tumor with central hyperechoic region in one. The echogenicity was related to the tumor size. The tumor margin was not clear in two patients. All the tumors were seen in the subcutaneous space of the chest wall or just above the liver surface. Conclusion: Chest wall tumor implantation due to biopsy or aspiration of HCC is rare, but should be kept in mind. During examination of an HCC patient who has previously received a tumor biopsy, chest wall implantation might be observed. The tumors are usually hypoechoic to isoechoic, depending on tumor size.
