An unusual initial presentation of hepatocellular carcinoma as a sellar mass
نویسندگان
چکیده
Sellar masses are frequently adenomatous pituitary tumors. Metastatic disease is unusual, often mimicking the presentations of adenomas. Hepatocellular carcinoma (HCC) is the most common primary hepatic malignancy but unusual to have a pituitary metastasis (PM). A 65-year-old man presented with headache, diplopia, ptosis, decreased vision in the right eye and unintentional weight loss of 32lbs. Preliminary out-patient work-up revealed a mass in the pituitary region. Cranial imaging showed 3.1 cm × 3.2 cm × 4.4 cm lesion. Abdominal imaging (computed tomography and magnetic resonance imaging) demonstrated a lobulated, nodular and heterogeneous right lobe of the liver. Trans-sphenoidal resection of the sellar mass favored metastatic HCC on histology. Liver biopsy confirmed HCC. We recommend maintaining an increased clinical suspicion upon evaluation of nonclassical clinical and radiological presentations of suspected PM/malignancy; as well as pursuing additional investigations in all early cases.

Introduction:Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis sec...

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC synd...
