Endoscopic and exoscopic surgery for brain tumors
Nerves and blood vessels must be protected during brain tumor surgery, which has traditionally relied on microscopes. In the 2000s, endoscopes and related equipment were developed for neurosurgery. In this rev...

Syndrome of inappropriate secretion of antidiuretic hormone as an initial sign of primary central nervous system lymphomas in the hypothalamus
Primary central nervous system lymphoma (PCNSL) rarely originates in the hypothalamus. Hypothalamic PCNSL can present with various symptoms specific to dysfunction of the hypothalamus, including consciousness ...

Thyrotropin-secreting pituitary adenomas induce left atrial enlargement with subclinical atrial fibrillation: an echocardiographic study
Thyrotropin-secreting pituitary adenoma (TSHoma) is rare but occasionally causes cardiovascular complications such as atrial fibrillation (AF) due to hyperthyroidism. Graves' disease (GD) is a common hyperthyr...

Oculomotor nerve palsy in pituitary apoplexy associated with pituitary adenoma: a radiological analysis with fast imaging employing with steady-state acquisition
Oculomotor nerve palsy (ONP) occasionally occurs in cases of pituitary apoplexy (PA) associated with pituitary adenoma, but its mechanism remains unclear. Intracranial nerves are clearly visualized by fast-ima...

Radiological and endocrinological evaluations with grading of hypothalamic perifocal edema caused by craniopharyngiomas
Hypophysial and hypothalamic dysfunction caused by craniopharyngioma is a serious problem despite the progress of surgical approaches and techniques. Perifocal edema induced by craniopharyngioma could be specu...

The clinicopathological analysis of receptor tyrosine kinases in meningiomas: the expression of VEGFR-2 in meningioma was associated with a higher WHO grade and shorter progression-free survival
WHO grade II/III meningiomas recur frequently and there is currently no established molecular target therapy for meningioma. No previous studies have revealed the association between receptor tyrosine kinases ...

Prediction of postoperative diabetes insipidus using morphological hyperintensity patterns in the pituitary stalk on magnetic resonance imaging after transsphenoidal surgery for sellar tumors
Diabetes insipidus (DI) remains a complication of transsphenoidal surgery (TSS) for sellar and parasellar tumors. Antidiuretic hormone (ADH) appears as hyper intensity (HI) in the pituitary stalk and the poste...

Internal carotid arterial shift after transsphenoidal surgery in pituitary adenomas with cavernous sinus invasion
The intercarotid distance (ICD) between cavernous carotid arteries (CCAs) is an important factor for avoiding injury of the internal carotid artery during transsphenoidal surgery. The ICD between CCAs in pitui...
