An unusual orbital lesion: hepatoma metastatic to the orbit

Orbital Metastasis as Initial Clinical Presentation in a Patient of Hepatocellular Carcinoma – A Rare Case with Review of Literature

Orbital metastasis, as the initial clinical presentation in hepatocellular carcinoma (HCC), is a rare manifestation. A 66-year-old male patient presented with a history of protrusion of the eyeballs, double vision, and swelling over the left side of the head for 8 months. Magnetic resonance imaging of the brain with orbit revealed a heterogeneous lesion in the left frontal lobe causing its destruction with intraorbital and intracranial extension. Triphasic contrast-enhanced computed tomography was suggestive of multiple hypodense areas in both lobes of the liver. Tissue diagnosis from the liver was suggestive of HCC. A diagnosis of multifocal HCC with orbital metastasis was made. The patient was treated with palliative radiotherapy and sorafenib. Orbital metastasis in HCC is rare. Prognosis is somber in such cases. The treatment should focus on providing palliation from symptoms.

Solitary skull metastasis as the first symptom of hepatocellular carcinoma: case report and literature review

Skull metastasis from hepatocellular carcinoma (HCC) is reported rarely. In addition, solitary skull metastasis as the first symptom of HCC is reported even less. Here, we reported a case of solitary skull metastasis as the first symptom of HCC and reviewed the literature on skull metastasis. A 49-year-old male patient was admitted to Jinjiang Hospital of Quanzhou Medical College with a painless parietal-occipital scalp mass, and he denied any history of hepatic disease. A cranial computed tomography demonstrated a hypervascular enhancement with osteolytic change in the right parietal-occipital region, cranial magnetic resonance imaging indicated a highly enhanced and osteolytic skull tumor, and abdominal computed tomography showed a huge tumor in the liver. The other examinations showed no other metastases. Laboratory data showed no liver dysfunction while hepatitis B surface antigen was positive, and alpha fetal protein level was high. A craniectomy was performed and the mass was totally removed. The histological diagnosis was skull metastasis from HCC. The patient was subsequently treated by transcatheter arterial chemoembolization. In a review of published literature, the incidence of skull metastasis from HCC in the period between 1990 and 2011 has significantly increased. The misdiagnosis rate of skull metastases as the first symptom from HCC was high. Therefore, it is necessary to give each patient with a scalp mass that has invaded the skull a liver ultrasound or computed tomography scan. On the other hand, we found that metastases that occurred in the calvaria site were more frequent than those that occurred in the skull base and facial skeleton. This may be worthy of further investigation in the future.

Bilateral multiple extraocular muscle metastasis from hepatocellular carcinoma

Hepatocellular carcinoma (HCC) rarely metastasizes to the extra ocular muscles (EOMs). We present a case of bilateral metastasis of HCC to the EOMs and focus on the magnetic resonance imaging (MRI) features. Orbital MRI revealed nodular enlargement of bilateral multiple EOMs, with isointensity on T1-weighted images and heterogeneous, intermediate-to-high signal intensity on T2-weighted images, and showed mild-to-significant heterogeneous contrast enhancement with gadolinium. Physicians should be aware of this rare cause of EOM enlargement, understand the radiologic characteristics of EOM metastasis, and thus make appropriate treatment strategy.

Complete response to radiation therapy of orbital metastasis from hepatocellular carcinoma

The incidence of hepatocellular carcinoma (HCC) is increasing in the United States, and 50%-75% of patients with HCC will develop metastatic disease. Orbital metastases from HCC are extremely rare. We report the case of a 52-year-old male with known metastatic HCC, who presented with severe proptosis and diplopia. An orbital mass was identified on magnetic resonance imaging (MRI) and confirmed to have hypermetabolic activity on positron emission tomography/computed tomography. He received a palliative course of external beam radiation therapy to the right orbit. Intensity modulated radiation therapy (IMRT) was used to allow sparing of critical normal tissues in close proximity to the tumor. One month after completion of IMRT to 58 Gray in 30 fractions delivered over 6 wk, the patient had a complete clinical, radiologic (MRI) and symptomatic response. The patient continues to have local control in the orbit 1.7 years after therapy completion. All critical normal structures were kept below the tolerance dose using IMRT, and no toxicities were observed.

Orbital metastasis of hepatocellular carcinoma

We report a 74-year-old woman who presented with an orbital apex syndrome and pulsatile proptosis. CT showed a right orbital mass that destroyed the orbital sphenoid bone and extended intracranially. Biopsy revealed metastatic hepatocellular carcinoma (HCC), and subsequent investigations demonstrated a high level of serum-fetoprotein and a huge liver mass. The patient died shortly after the biopsy. Rarely reported in the English literature, metastatic HCC is common in Asia, perhaps because of a racial predisposition together with a relatively high prevalence of alcoholic cirrhosis, chronic hepatitis B and C, and exposure to aflatoxins.

Skull metastasis from hepatocellular carcinoma

Metastasis to the skull frequently occurs in patients with lung, breast and prostate cancer. However, skull metastases from hepatocellular carcinoma (HCC) have been rarely reported. We review the literature on skull metastasis from HCC and report a case of a 46-year-old male, who was diagnosed as HCC and was operated on by trans-arterial embolization and lobectomy in Oct. 2004. He complained of a painless mass over the left frontal region for two months. Radiograph of the skull revealed an osteolytic mass about 4-5 cm in size over the left frontal region. A cranial computerized tomography demonstrated a destructive lesion with soft tissue mass over the left frontal region. A left frontal craniectomy was performed and tumor was totally removed. The histological diagnosis was cranial metastasis from HCC. Postoperative recovery was uneventful without any neurological deficits. Because of improved and advancing treatment for HCC, survival time for HCC has been lengthened and distant metastases will thus be found to increase. Early diagnosis is essential to treat the primary disease. Skull metastases from HCC should be considered as a differential diagnosis in patients with scalp subcutaneous mass and osteolytic defect on X-ray skull films.

Orbital metastasis from hepatocellular carcinoma

We report a case of orbital metastasis from hepatocellular carcinoma and review the literature. A 45-year-old healthy male patient presented with proptosis due to an orbital mass. Histopathologic examination indicated that the tumor was a secondary from a hepatocellular carcinoma, and further investigations revealed the primary tumor in the liver. Hepatocellular carcinoma is a rare source of metastasis to the orbit, and to our knowledge, only 14 histopathologically proven cases have been reported previously. Proptosis was the most common presenting feature in the reviewed reports. A majority of patients had occult primary tumors at presentation and the diagnosis of the orbital mass was based on histopathologic features.

Metastatic tumors of the orbit: a retrospective study

PURPOSE

To present the clinical features and facts on prognosis, therapy and diagnostics of orbital metastases treated in the Orbital Center Kiel.

METHODS

We reviewed the records of 20 patients with orbital metastases (ca. 2% of all orbital patients seen in a 10-year period).

RESULTS

The mean age at first manifestation of orbital symptoms was 64 years. On average, 64 months was the period of time between the onset of the primary disease and orbital manifestation. The sites of the primary tumors were breast (8), choroid (2), prostate (2), gastrointestinal tract (3), lung (2), urinary bladder (1), Schmincke tumor of the throat (1) and unknown origin (1). Eleven patients were female, 9 male. The main primary symptoms consisted of lid swelling (11), red eye (9), diplopia (10), and proptosis (7). Although the majority (16/20) were treated by chemotherapy, radiotherapy or surgery, 19 patients died after a mean survival time of 14.7 months.

CONCLUSION

Orbital metastases remain an unfavorable prognostic factor, but the diagnosis and treatment are still important in order to prevent loss of vision and improve the patient's quality of life. As previous studies have shown, the overall survival rate is still as limited as nearly half a century ago.

Cancer metastatic to the orbit: the 2000 Robert M. Curts Lecture

PURPOSE

To report the demographics and clinical features of a large series of patients with orbital metastasis.

METHODS

Retrospective chart review on 100 consecutive patients and a literature review on orbital metastasis.

RESULTS

Of 100 patients, the primary tumor site was breast in 53 (53%), prostate gland in 12 (12%), lung in 8 (8%), skin (melanoma) in 6 (6%), kidney in 5 (5%), gastrointestinal tract in 5 (5%), choroid (melanoma) in 2 (2%), parotid gland in 1 (1%), and adrenal gland (neuroblastoma) in 1 (1%). Of patients in whom a detailed history was available, there was no history of cancer at the time of presentation in 19%. In 10%, the primary tumor remained undetected despite systemic evaluation. There were 36 male patients and 64 female patients whose mean age at diagnosis was 62 years (median 60 years, range 5 to 91 years). Both the right and left orbits were affected equally, and 4 cases (4%) were bilateral. The most frequent clinical findings were limited ocular motility (54%), proptosis (50%), and palpable mass (43%). The diagnoses were established by history, systemic survey, imaging studies, and biopsy. Treatment included chemotherapy, hormone therapy, irradiation, surgical excision, or observation, depending on clinical circumstances. Among patients with sufficient follow-up, 95% died of metastasis, with overall mean survival of 15 months (median 15 months; range 3 to 96 months) after orbital diagnosis.

CONCLUSIONS

The most common primary cancers that metastasize to the orbit are breast, prostate gland, and lung cancer. In 19%, there is no history of cancer when the patient presents with ophthalmic symptoms and in 10% the primary site remains obscure despite systemic evaluation. The systemic prognosis is generally poor.

[Hepatocellular carcinoma: a case revealed by metastatic orbital tumor]

INTRODUCTION

We report a case of metastatic orbital tumor revealing hepatocellular carcinoma.

EXEGESIS

Metastatic orbital tumors of hepatocarcinoma are rare. Only six cases have been reported. We compare these cases to our observation. Treatment of the orbital metastasis is important to decrease pain, ophthalmological symptoms and to improve the quality of survival. Radiotherapy and/or surgery can be used. Prognosis for life depends on liver involvement: the modalities of treatment of the hepatocarcinoma have to be discussed for each patient.

CONCLUSION

Seven cases of orbital metastasis revealing a hepatocarcinoma have been documented. Effectiveness of radiotherapy makes the local prognosis good, but prognosis depends on liver involvement, since prognosis of hepatocellular carcinoma is poor.

Hepatocellular carcinoma metastasizing to the orbit diagnosed by fine needle aspiration cytology

Hepatocellular carcinoma (HCC) rarely metastasizes to the orbit. We report a case of a 78-year-old man with a past history of HCC, who presented with a periorbital mass, which was diagnosed as metastatic HCC by fine needle aspiration cytology (FNAC) and subsequently confirmed on excision biopsy. The cytological, histopathological and immunohistochemical findings are presented and the differential diagnosis is discussed. To our knowledge there has been no previously reported case of HCC metastatic to the orbit diagnosed by FNAC.
