To investigate the clinical characteristics of hypopituitarism and its reversibility after surgery for nonfunctional pituitary adenoma (NFPA); analyze the correlation between tumor size and hypopituitarism incidence; and predict hypopituitarism by tumor volume and maximum diameter. ⋯ NFPA has a significant influence on gonadal hormone, IGF-1/GH, and thyroid hormone. NFPA can cause single- or multiple-hormone reduction in each pituitary target gland. Tumor size is positively correlated with the incidence and degree of hypopituitarism. NFPA-induced hypopituitarism is significantly recovered after surgical treatment.

Characteristics of Spinopelvic Sagittal Alignment in Lumbar Degenerative Disease.
Normal sagittal alignment shows a range of variations and normal values. This study compared sagittal vertebral alignment in patients with different degenerative lumbar diseases. ⋯ Pelvic incidence may play a predisposing role in the pathogenesis of lumbar degenerative disease. Patients with degenerative spondylolisthesis have greater pelvic incidence with increased lumbar lordosis. In contrast, patients with spinal stenosis have lower pelvic incidence with flatter lumbar lordosis.

Experiencing a ventriculoperitoneal (VP) shunt complication is a major obstacle in the management of hydrocephalus. Degradation of a shunt catheter associated with surrounding tissue calcification could be 1 reason for a difference in facture rates. Furthermore, tissue reactions around cerebrospinal fluid shunts may be a sign of bacterial shunt infection, which is not uncommon. ⋯ We treated a rare case of shunt dysfunction caused by calcification of the aponeurosis coinciding with significant weight gain over the course of a year. To the best of our knowledge, this is the first report to describe a case of shunt malfunction caused by calcification of the aponeurosis.

This report discusses the risks and complications of using the extended endoscopic endonasal transsphenoidal approach (EEETA) in a special craniopharyngioma case to caution neurosurgeons. ⋯ The coexistence of severe calcified craniopharyngiomas, especially with sharp calcified spurs, a narrow distance between the anterior communicating artery and the planum sphenoidale, and a narrow distance between the bilateral internal carotid arteries is a significant warning signal during EEETA for craniopharyngiomas. In this circumstance, it may be preferable to use open microsurgical approaches. If the anterior communicating artery or anterior cerebral artery is punctured during EEETA, another method is available to fix the problem using an aneurysm clip through the nose, and not only endovascular embolization.

To delineate the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of patients with cervical spondylotic radiculopathy by diffusion tensor imaging and fiber bundle tracing. ⋯ Fiber tractography is capable of delineating microstructural changes of cervical nerve roots and cervical spondylotic radiculopathy exhibits significant changes in FA and ADC values.
