Introduction. Endonasal endoscopic approach has entered recently like a strong option for pituitary tumors treatment. Material and method. A prospective, controlled, randomized and double blind surgical assay was carried out in 41 patients with regional sellar lesions between August 2002 and July 2004. Effectiveness of this method in relation to the microscopic transphenoidal one was evaluated....

Skull base tumors that involve the cavernous sinus (CS) present a challenge to the endoscopic surgeon. Most such lesions arise from sellar pathology that involves the medial wall of the CS, which can be accessed by a transsphenoidal transsellar approach. Tumors that arise primarily in the medial CS may be accessed via a transethmoidal transsphenoidal parasellar approach, which avoids the dissec...

RATIONALE Chondromyxoid fibroma (CMF) is a rare benign bone neoplasm which often occurs in the lower extremities. Little is known about the radiological and histological presentation of CMF in the sellar region. PATIENT CONCERNS A 16-year-old Asian male presented to the hospital 12 months ago with bilateral diplopia involving right visual fields, intermittent headaches, and dizziness. INTER...

Background: Xanthogranuloma of the sellar region is an extremely rare benign entity with only case reports and series documented in literature. We aim to describe this report a suprasellar xanthogranuloma that was diagnosed initially as cystic craniopharyngioma. Case Description: A 28-year-old woman presented clinic 2-week history headaches, blurred vision, nausea, vomiting. She had no medical ...

Spindle cell oncocytoma (SCO) is a rare and recently described neoplasm arising from the pituitary adenohypophysis thought to be derived from the folliculostellate cells. Even though SCO has been classified as a distinct World Health Organization (WHO) grade I tumor, sellar neoplasms with an oncocytic appearance are uncommon and have a wide differential diagnosis that includes primary and metas...

Intracranial metastases from laryngeal carcinoma are rarely clinically diagnosed. To our knowledge, this is the first report of hypopituitarism due to pituitary metastasis from laryngeal carcinoma. We report on a 70-year-old man who had a supraglottic squamous cell carcinoma, which was resected surgically followed by local full dose radiation therapy. Four months later, he presented with a sudd...

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....
