We evaluated the prognostic and clinical value of radiological findings including prevertebral hyperintensity (HI), cord compression, intramedullary high-signal intensity (IMHSI) and instability in patients with traumatic central cord syndrome without evidence of fracture and dislocation. ⋯ The presence of prevertebral HI, IMHSI, and cord compression influenced the neurologic status of the patients. The instability was significantly associated with poor prognosis for neurologic outcome. Prevertebral HI on T2 MR imaging may be a possible indicator of instability in patients with central cord syndrome after hyperextension injury.

This study used high-resolution magnetic resonance (MR) imaging (1.5 T) to define and evaluate preoperative imaging criteria for cavernous sinus invasion (CSI) by pituitary adenoma (PA). ⋯ The preoperative diagnosis of CSI by PA is extremely important because endocrinologic remission is rarely obtained after microsurgery alone in patients with invasive tumors. The aforementioned MR imaging criteria may be useful in patient's management and in advising most of the patients preoperatively on the potential need for complimentary therapy after surgery.

Parasagittal meningioma is one that fills the parasagittal angle, with no brain tissue between the tumor and the SSS. Invasion of the SSS is a challenge for complete removal and, consequently, for recurrence of these tumors. The objective of this study was to analyze the factors that influenced the clinical outcome of patients with parasagittal tumors surgically treated. ⋯ Recurrence of parasagittal meningiomas predominated in males, in grades II/III tumors, after subtotal resection, and with more invasion of the SSS. Subtotal or total resections without sinus resection were considered adequate for treating these patients.

Fractionated stereotactic radiotherapy (FSRT) combines the precision of stereotactic positioning with the radiobiologic advantage of dose fractionation. ⋯ Fractionated stereotactic radiotherapy is a high-precision technique. It is safe and feasible in the primary and adjuvant treatment of cavernous sinus meningiomas. Fractionated stereotactic radiotherapy allowed local control in more than 90% of patients.

Comparative Study
Head injuries in adolescents in Taiwan: a comparison between urban and rural groups.
Data pertaining to head injuries in adolescents in Taiwan are scarce. The purpose of this study was to investigate the trend and pattern of head injuries in adolescents in both urban and rural areas in Taiwan. ⋯ The causes, patterns, and outcomes of head injury were statistically different between the 2 age groups of adolescents in urban and rural areas. Further studies on adolescent head injury are necessary.
