Review Case Reports
Metastatic thymic carcinoma presenting as a posterior fossa mass: case report and review of the literature.
Thymic epithelial tumors (TETs) are uncommon lesions, and cerebral metastases from these tumors are even rarer. We report a case of a posterior fossa metastasis in a patient with a known history of thymic carcinoma. ⋯ Metastasis should be considered in the differential of a patient with a TET and an intracranial mass lesion.

Multicenter Study
Long-term Prognosis of Spontaneous Intracerebral Hemorrhage on the Tibetan Plateau: A Prospective Cohort study at Two Hospitals.
Patterns of intracerebral hemorrhage (ICH) and outcomes in Tibetans are poorly understood. We aimed to investigate the long-term outcomes of Tibetan ICH patients. ⋯ Most cases of ICH on the Tibetan Plateau involve concomitant hypertension. Tibetan patients are at higher risk of disability or disability/death on follow-up than are patients from Chengdu Plain.

Multicenter Study
Surgeon and patient's radiation exposure through vertebral body cement augmentation procedures: a prospective multicentric study of 49 cases.
Vertebral body cement augmentation as a treatment option for osteoporotic or traumatic fractures has become increasingly popular during the past decade. However, these surgical procedures require numerous fluoroscopic examinations, resulting in high radiation exposure for the patient and the surgical team. The aim of this study was to evaluate the level of radiation exposure of the spine surgeon and the patient during these percutaneous procedures. ⋯ Values of radiation doses for surgeon and patient were lower than those reported in the previous literature. The recommended annual dose limit is set to 500 mSv for extremities and 150 mSv for lens. According to our results, the exposure dose to the eye exceeds the annual limit after 3500 procedures. However, there is increasing concern among surgeons about radiation exposure, and there is still a need for solutions as preventive measures.

Stereotactic radiosurgery (SRS) for large vestibular schwannomas (VS) remains controversial. We studied the tumor local control and toxicity rates after hypofractionated SRS for VS > 3 cm. ⋯ Overall, 80% of large VSs were adequately controlled by CK with 97 months of median follow-up. Patients with previous surgery and NF2 also appeared to have higher rates of tumor progression, and less favorable functional outcomes.

To evaluate whether preoperative multirow detector computed tomography (MDCT) findings were associated with clinical outcome 24 months after dynamic stabilization for painful degenerative lumbar spine disease. ⋯ Clinical improvement after dynamic stabilization was significantly associated with 7 independent baseline imaging findings. Preoperative evaluation of these MDCT parameters may improve therapy selection for patients with degenerative lumbar spine disease.
