Hepatocellular carcinoma with metastasis to the skull base, pituitary gland, sphenoid sinus, and cavernous sinus

Abstract:
Two cases of hepatocellular carcinoma, with metastases to the skull base, pituitary gland, sphenoid sinus, and cavernous sinus are reported. Patients presented with diplopia, retro-orbital headache, and multiple cranial nerves palsies. Pituitary metastases may require surgery as palliative treatment, and for the confirmation of histology. One of the current cases was diagnosed with hepatocellular carcinoma prior to transphenoidal resection of the pituitary metastasis. The second patient was found to have hepatocellular carcinoma after review of histology, and the development of signs and symptoms relating to the primary tumour.
Insights
Hepatocellular carcinoma can metastasize to the skull base, affecting cranial nerves and causing symptoms like double vision. Surgery may be needed for diagnosis and palliative care in these rare cases.
Area of Science:
- Oncology
- Neurology
- Otolaryngology
Background:
- Hepatocellular carcinoma (HCC) is a primary liver cancer.
- Metastasis of HCC to the skull base is rare.
- Skull base metastases can present with neurological deficits.
Observation:
- Two cases of HCC with metastases to the skull base, pituitary gland, sphenoid sinus, and cavernous sinus are presented.
- Patients experienced symptoms including diplopia, retro-orbital headache, and multiple cranial nerve palsies.
- These symptoms indicate significant neurological and orbital involvement.
Findings:
- Pituitary metastases from HCC can be diagnosed pre-operatively or incidentally via histology.
- Transsphenoidal resection of pituitary metastases can be both diagnostic and palliative.
- Histological confirmation is crucial for identifying HCC as the primary source.
Implications:
- This highlights the importance of considering HCC metastasis in patients with unexplained cranial nerve palsies and skull base lesions.
- Surgical intervention for pituitary metastases may offer symptomatic relief and diagnostic confirmation.
- Early recognition and diagnosis of HCC metastasis are vital for patient management.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
