Hepatocellular carcinoma (HCC) rarely invades the gastrointestinal (GI) tract. It occurs in 0.7% to 2% of clinical HCC cases. Moreover, gastric invasion with GI hemorrhage via peritoneal seeding is very rare. We report the case of 67-year-old woman who had a history of HCC rupture and was admitted due to left upper quadrant abdominal pain. The patient was diagnosed with three omental metastatic masses and underwent hepatic segmentectomy and omental tumorectomy. Two months later, the patient had massive melena, and an esophagogastroduodenoscopy showed very large ulcerated friable mass on the gastric body. The histology was consistent with the diagnosis of metastatic HCC. The patient died from persistent GI hemorrhage 93 days after the admission. This case illustrates the very rare event of peritoneal seeding of a ruptured HCC causing direct invasion of the stomach, followed by GI hemorrhage.

OBJECTIVE: To describe computed tomography (CT) features of metastatic gallbladder (GB) tumors (MGTs) from various primary tumors and to determine whether there are differential imaging features of MGTs according to different primary tumors. MATERIALS AND METHODS: Twenty-one patients who had pathologically confirmed MGTs and underwent CT were retrospectively enrolled. Clinical findings including presenting symptoms, type of surgery, and interval between primary and metastatic tumors were recorded. Histologic features of primary tumor and MGTs including depth of invasion were also reviewed. Imaging findings were analyzed for the location and morphology of MGTs, pattern and degree of enhancement, depth of invasion, presence of intact overlying mucosa, and concordance between imaging features of primary and metastatic tumors. Significant differences between the histologies of MGTs and imaging features were determined. RESULTS: The most common primary tumor metastasized to the GB was gastric cancer (n = 8), followed by renal cell carcinoma (n = 4) and hepatocellular carcinoma (n = 3). All MGTs (n = 21) manifested as infiltrative wall thickenings (n = 15) or as polypoid lesions (n = 6) on CT, similar to the features of primary GB cancers. There were significant differences in the morphology of MGTs, enhancement pattern, enhancement degree, and depth of invasion according to the histology of primary tumors (p < 0.05). Metastatic adenocarcinomas of the GB manifested as infiltrative and persistently enhancing wall thickenings, while non-adenocarcinomatous metastases usually manifested as polypoid lesions with early wash-in and wash-out. CONCLUSION: Although CT findings of MGTs are similar to those of primary GB cancer, they are significantly different between the various histologies of primary tumors.

Extrahepatic metastasis in patients with hepatocellular carcinoma (HCC) occurs frequently. The most common site of metastasis is the lung, followed by regional lymph nodes and bones. However, gastrointestinal metastasis of HCC is a rare condition and solitary polypoid metastatic lesion on stomach without any evidence of direct invasion from primary mass is very rare. These metastatic lesions are usually asymptomatic, and most are discovered at postmortem examination or are found incidentally during laparotomy. The choice of treatment for gastrointestinal metastatic lesion of HCC includes surgery, transarterial chemoembolization, and local injection but the treatment is often difficult and unsuccessful. We report a case of 69 years old man who presented disappearance of a polypoid metastatic lesion of HCC on the gastric fundus by transarterial chemoembolization.

Endobronchial metastasis (EBM) secondary to extrathoracic malignancies is rare among the various modes of pulmonary metastases. Of the many types of extrathoracic tumors capable of EBM, only one case of EBM from hepatocellular carcinoma has been reported, but radiologic findings were not described. We present the radiologic findings of surgically proven EBM in a patient with hepatocellular carcinoma. A chest radiograph revealed a tubular mass-like opacity in the right suprahilar region combined with mild volume decrease of the right upper lobe. Fiberoptic bronchoscopy had erroneously led to a diagnosis of endobronchial aspergilloma. The metastatic lesion was manifested as a branching pattern of enhanced endobronchial mass at the anterior segment of the right upper lobe on computed tomography.

Spontaneous regression of hepatocellular carcinoma (HCC) is extremely rare. We report a case of 67-year-old man having HBV-associated HCC with multiple lung metastases which regressed spontaneously. The patient had single liver mass and received surgical resection. The mass was confirmed as HCC histopathologically. Nine years after surgical resection, a 3.3 cm sized recurred HCC was detected on the resection margin in CT scan. Transarterial chemoembolization (TACE) was performed 3 times, and lung metastases developed thereafter. The patient received 2 more sessions of TACE, however, metastatic lung nodules were in progress very rapidly. We decided to stop TACE and followed the patient regularly without any anti-cancer treatment. Nine months after development of lung metastasis, the size and number of metastatic lung nodules decreased and were not detected anymore after 14 months. Serum alpha-fetoprotein levels also decreased to normal range and no viable tumor was noted in the liver. The patient is still alive 12 years after the first diagnosis of HCC and 16 months after lung metastasis developed.

Reports of metastatic hepatocellular carcinoma (HCC) without a primary liver tumor are rare. Here we present a case of isolated HCC that had metastasized to the pelvic bone without a primary focus. A 73-year-old man presented with severe back and right-leg pain. Radiological examinations, including computed tomography (CT) and magnetic resonance imaging (MRI), revealed a huge mass on the pelvic bone (13x10 cm). He underwent an incisional biopsy, and the results of the subsequent histological examination were consistent with metastatic hepatocellular carcinoma. The tumor cells were positive for cytokeratin (AE1/AE3), hepatocyte paraffin 1, and glypican-3, and negative for CD56, chromogranin A, and synaptophysin on immunohistochemical staining. Examination of the liver by CT, MRI, positron-emission tomography scan, and angiography produced no evidence of a primary tumor. Radiotherapy and transarterial chemoembolization were performed on the pelvic bone, followed by systemic chemotherapy. These combination treatments resulted in tumor regression with necrotic changes. However, multiple lung metastases developed 1 year after the treatment, and the patient was treated with additional systemic chemotherapy.

Bone is a common site of metastasis in patients with hepatocellular carcinoma (HCC). We report a rare case of rib metastasis from HCC treated by transcatheter arterial chemoembolization (TACE). A 55-year-old man with liver cirrhosis presented with right lower chest pain. The diagnosis was an HCC with a bone metastasis in the right eighth rib. Intra-arterial injections of doxorubicin mixed with Lipiodol and Gelfoam particles were instituted through the right eighth intercostal artery. Computed tomography and a Tc99-labeled scan performed 2 months after the third TACE revealed no viable HCC in the right eighth rib.

Transcatheter arterial chemoembolization (TACE) has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.
