Unusual case of skull metastasis from hepatocellular carcinoma

Isolated calvarial lesion as the initial presentation of metastatic hepatocellular carcinoma: A case report and review of the literature

Background

Hepatocellular carcinoma (HCC) contributes significantly to global cancer-related mortality, often because patients present at advanced stages of the disease. HCC commonly metastasizes to the lung, abdominal lymph nodes, and bone. However, even among bony metastases, calvarial lesions are exceptionally rare, especially in the initial presentation.

Case Description

We describe a unique case of a 65-year-old African American woman who presented with a rapidly growing skull lesion as her first clinical sign of metastatic HCC. Imaging revealed an extensive soft-tissue mass involving the left calvaria and partially obstructing the superior sagittal sinus. We suspected that the lesion was a meningioma and offered surgery. Histological examination and further systemic workup later confirmed HCC. She was started on adjuvant therapy but unfortunately deteriorated from complications secondary to disease progression. We also reviewed the literature on cases of isolated calvarial metastases as the initial presentation of HCC. A total of 36 case reports were reviewed which included 38 patients. There were 32 males (84.2%), and the mean age was 58.97 ± 9.09 years old. The most common location of presentation was the parietal or occipital region (13, 34.2%), and 18 patients (47.4%) underwent neurosurgical treatment of the lesion. Among the 26 cases that had a follow-up, 84.6% (n = 22) did not survive treatment, and the mean survival time was 6.15 ± 5.94 months.

Conclusion

Isolated calvarial lesions are rarely the initial presenting sign of metastatic HCC. Often, these lesions may be misdiagnosed as benign tumors, such as meningiomas or hemangiopericytomas, given their appearance on imaging. However, early identification of HCC skull lesions is crucial to initiating treatment, including resection, radiation, and immunotherapy, which may help improve symptoms and extend survival. Our case report adds to the limited literature on this exceedingly rare entity.

Skull Metastasis With Orbital Invasion as a Primary Manifestation of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is a common worldwide cancer with a poor prognosis despite treatment advancements. Patients typically exhibit signs and symptoms pertaining to the liver. Extrahepatic metastasis of HCC is documented to be as low as 5% of cases. Bone metastasis ranks third following lungs and regional lymph nodes. The typical locations for bone metastasis include the vertebral column, pelvis, femora, and ribs, with skull metastasis, being reported in less than 1.6% of cases. Herein, we describe a case of HCC presenting with skull metastases and orbital invasion as the initial manifestation.

Response of Scalp and Skull Metastasis to Anti-PD-1 Antibody Combined with Regorafenib Treatment in a Sorafenib-Resistant Hepatocellular Carcinoma Patient and a Literature Review

Background

Scalp and skull metastasis of hepatocellular carcinoma (HCC) is extremely rare. Modalities for the treatment of this disease include craniotomy, radiotherapy and chemotherapy, which are unsatisfactory. We report a case of HCC with scalp and skull metastasis and review similar cases from the literature to accumulate experience for better management of this type of HCC metastasis.

Case Presentation

A 54-year-old female was diagnosed with advanced HCC with posterior portal vein tumor thrombus (PVTT) at admission. She received laparoscopic microwave therapy for a large tumor in Segment 6, which was then followed by sorafenib therapy. One year later, sorafenib resistance developed, metastasis occurred in the scalp and skull, left sacroiliac joint, and lung; PVTT extended into the main portal vein and alpha-feta protein (AFP) levels exceeded 65,000 ng/mL. Systemic therapy was then substituted by regorafenib combined with sintilimab. Three months later, AFP decreased to 2005 ng/mL; meanwhile, skull and lung metastatic lesions shrank significantly. Furthermore, both lump and limp disappeared. One year after the combination of regorafenib and sintilimab, skull and lung metastasis, and PVTT were completely relieved. Moreover, primary liver lesions showed no sign of activity. With comprehensive therapy, the patient has survived for 5 years and 7 months.

Conclusion

Sorafenib-regorafenib sequential treatment combined with sintilimab is safe and effective when used to treat HCC skull metastasis, for which high-level evidence is needed to support this treatment strategy.

Chronic Subdural Hematoma Caused by Calvarial and Dural Metastasis from Uterine Leiomyosarcoma

Uterine Leiomyosarcoma (uLMS) is an aggressive tumor with poor clinical outcome. Skull and dural metastasis from uterine uLMS is exceptionally rare. We report a 60-year-old woman who had a 6 months' history of per vaginal bleed and abdominal pain who presented to us in a confused state and raised intracranial pressure symptoms with swelling over her right frontal-temporal region. She underwent excision of the right frontal-temporal tumor and evacuation of a right subdural hematoma (SDH), which greatly improved her condition. Postoperatively, she underwent adjuvant radiotherapy and chemotherapy. This case highlights the importance of clinical suspicion to diagnose patients with this rare metastasis to this region and the appropriate subsequent treatment. We herein report a rare case of metastatic uLMS with skull and dural metastasis that presented with SDH.

Solitary scalp metastasis - a rare presentation of hepatocellular carcinoma

Introduction

Hepatocellular carcinoma (HCC) is among the commonest cancers in the world. Metastasis is one of the most significant factors affecting prognosis. Common sites of extrahepatic metastases include lungs, regional lymph nodes and less commonly bone.

Case presentation

A 56-year-old male presented with a painless occipital scalp lump of three months duration, with recent rapid enlargement. His skull x-ray showed a lytic lesion over occipital bone and the contrast CT scan of the brain showed a scalp mass with destruction of the adjacent skull. Core biopsy of the lesion revealed a metastatic deposit from a hepatocellular carcinoma.

Conclusion

Primary presentation with skeletal metastases are rare in HCC with only a few reported cases. Here we report a case of HCC presenting as a solitary scalp lump.

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.

Case report of skull metastasis from hepatocellular carcinoma after a liver transplant

A solitary skull metastasis from hepatocellular carcinoma is rare. A 38-year-old man with hepatocellular carcinoma presented to our institution with a palpable temporal scalp mass. We took a magnetic resonance image, and discovered an enhanced and osteolytic skull tumor. The tumor was removed by an occipital craniectomy, and the histologic diagnosis was a cranial metastasis owing to hepatocellular carcinoma. A skull metastasis owing to hepatocellular carcinoma should be considered in the differential diagnosis in patients with a subcutaneous scalp mass. Although a distant metastasis can affect the prognosis of the patient, early treatment may improve survival.

[Long survival after resection of cranial metastases from hepatocellular carcinoma. Case report and review of the literature]

The life expectancy of patients with hepatocellular carcinoma (HCC) has increased in the last few years due to recent treatment advances. However, extrahepatic metastases from tumors, previously described only occasionally, are becoming more frequent in clinical practice. The choice between an active or passive approach to these metastatic lesions can sometimes present clinicians with a difficult dilemma. We discuss the case of a male patient with multifocal HCC and cranial metastasis from a primary liver tumor and who, after surgery and radiotherapy over the metastatic lesion, has survived for more than 3 years.

Skull metastasis from hepatocellular carcinoma with chronic hepatitis B

A 56-year-old male visited our hospital for evaluation of an occipital mass. Contrast computed tomography showed hypervascular enhancement with osteolytic change in the skull and a huge enhanced mass in the liver. Magnetic resonance imaging showed bone metastasis in the thoracic vertebrae. Assays for hepatitis B surface antigen and hepatitis B core antibody were positive and his liver condition was Child-Pugh grade A. Our diagnosis was hepatocellular carcinoma (HCC) with skull and vertebrae metastases on chronic hepatitis B. He was treated with radiation therapy for bone metastases and transcatheter arterial chemoembolization for HCC. But he developed acute respiratory failure because of aspiration pneumonia, congestion and oedema with haemorrhage of the lungs and died. Dissection showed HCC with multiple bone metastases. The liver tumor was categorized as well-differentiated HCC, Edmondson classification I, trabecular type and pseudoglandular type. In the liver mild infiltration of lymphocytes was seen in Glisson’s capsules which were significantly enlarged with well preserved limiting plates. Piecemeal necrosis was not obvious. No fibrosis was noted. An 8 cm × 7 cm × 3 cm metastatic lesion had formed in the left occipitotemporal part of the cranial bone. The lesion was osteolytic and showed invasion into the dura mater. Neither the subdural cavity nor the brain showed involvement from the metastatic tumor. However, skull metastasis from HCC is very rare and it affects the patient’s prognosis and the quality of life. Therefore, it is very important to make an early diagnosis and carry out proper management of skull metastasis from HCC.

Multiple skull metastases from hepatocellular carcinoma successfully treated with radiotherapy

We report a Japanese man who presented with multiple cranial nerve palsies with hepatitis B virus-related multiple hepatocellular carcinoma (HCC). He presented with right III, IV, VI, IX, X, and XII cranial nerve palsies. Metastases involving the clivus and the right occipital bone from HCC were diagnosed by the findings of magnetic resonance imaging of the head, cerebral angiography, and 2-deoxy-2-[(18)F]fluoro-D-glucose positron emission tomography/computed tomography. In this case, over one-year survival and improvement of neurological signs were achieved by radiotherapy in spite of multiple skull metastases, which are extremely rare.

Spontaneous epidural hematoma due to skull metastasis of hepatocellular carcinoma

Although "spontaneous" epidural hematomas are rare, they can occur in patients with metastatic skull tumors. We describe a case caused by skull metastasis of hepatocellular carcinoma (HCC), and review the relevant literature. In patients with HCC, potential skull metastasis should be kept in mind, since skull metastases from HCC seem to often cause devastating epidural hematoma.

Solitary skull metastasis as initial manifestation of hepatocellular carcinoma

Background

A solitary skull metastasis from hepatocellular carcinoma (HCC) prior to diagnosis of the primary tumor without liver dysfunction is a very rare event.

Case presentation

A 71-year-old male, without known liver disease, presented to our institution with a palpable occipital scalp mass. On brain magnetic resonance imaging (MRI), a highly enhanced and osteolytic skull tumor was observed. The histological diagnosis obtained from the percutaneous needle biopsy was a cranial metastasis from HCC. The metastatic tumor was removed via occipital craniectomy, and the two primary liver mass lesions were subsequently treated by transarterial chemoembolization.

Conclusion

An isolated skull metastasis may be the sole initial presentation of HCC. Early diagnosis is essential in order to treat the primary disease. A skull metastasis from HCC should be considered in the differential diagnosis in patients with subcutaneous scalp mass and osteolytic defects on X-ray.

Homonymous hemianopia caused by solitary skull metastasis of hepatocellular carcinoma

We report a patient who developed a complete left homonymous hemianopia from mass effect of a solitary skull metastasis of hepatocellular carcinoma (HCC). After chemoembolization and resection, the visual field defect improved markedly. This is the first reported case demonstrating this phenomenon in HCC. It supports aggressive treatment of a solitary skull metastasis in this setting.

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.
