This is a surgical video that sheds light on the utility of a new imaging modality GLOW800 (Leica Microsystems, Wetzlar, Germany) in resection of vascular tumors. We describe the surgical resection of posterior fossa hemangioblastoma in 2 different patients after informed consent was obtained. ⋯ In addition, it helped in the confirmation of complete resection of the lesion. Another advantage of GLOW800 was that it allowed safe resection of the lesion in and around highly eloquent areas with a narrow surgical corridor (Video 1).

The present study evaluated the early death and factors associated with early mortality in patients with glioma. ⋯ The early deaths rates, including 1 and 3 months after tumor resection in patients with glioma, have decreased slightly during the previous 40 years. The risk factors for early mortality included advanced age, male sex, tumor located in the lateral ventricle, cerebellum, or brainstem, receipt of biopsy only, no chemotherapy or radiotherapy, and specific histopathological types.

To analyze the risks of the distal adding-on phenomenon and identify the ideal lowest instrumented vertebra (LIV) for Lenke IA and IIA. ⋯ An LIV located proximal to the LSTV should be avoided during selective thoracic fusion for Lenke IA and IIA to prevent the distal adding-on phenomenon. For patients who have a small thoracolumbar or lumbar curve size in bending films or a small T5-T12 angle before surgery, the next vertebra distal to the LSTV may be an optimal choice.

CO-OCCURRENCE OF CRANIOPHARYNGIOMA AND IgG4-RELATED HYPOPHYSITIS: AN EPIPHENOMENON OR A MERE CO-INCIDENCE?
Craniopharyngiomas are sellar-suprasellar tumors that commonly present in children, with nonspecific symptoms of increased intracranial pressure, visual disturbances, and pituitary insufficiencies. Rarely has secondary hypophysitis (lymphocytic and xanthogranulomatous) been reported in association with craniopharyngioma. ⋯ The present case might represent the first ever report, to the best of our knowledge, of secondary IgG4-related hypophysitis due to craniopharyngioma, or it might, perhaps, be a chance association of these 2 entirely different disease entities.

Klippel-Feil syndrome was first described in 1912; a short neck, low posterior hairline, and decreased cervical joint range of motion are the classical triad of this disease. In this syndrome, which is rarely observed, the characteristics that have been reported include the following: scoliosis; Sprengel deformity; cervical rib; ear, nose, oral, and laryngeal abnormalities; structural abnormalities of the urinary system; and congenital heart diseases. However, bilateral omovertebra and bilateral multilevel cervical ribs have not been reported. ⋯ Cases of Klippel-Feil syndrome may be accompanied by multiple abnormalities. We want to highlight the need for detailed examination of patients and lifestyle modification at an early age, before symptom appearance, as well as adaptation to habitual exercise.
