Review Case Reports
Cervical Periosteal Chondroma Causing Spinal Cord or Nerve Compression: 2 Case Reports and Literature Review.
Chondroma is a rare benign cartilaginous tumor that originates in chondrocytes and is commonly seen in the long bones; however, it infrequently occurs in the cervical spine. ⋯ The authors herein summarized 16 previous reports of cervical chondroma and compared the clinical courses and treatments. Recommended treatment included maximal surgical resection, especially when significant compression of the cervical cord and signal abnormality within the cord was observed. Annual postoperative follow-up is mandatory to ensure proper neurologic improvement.

Review Case Reports
Plurihormonal ACTH-GH Pituitary Adenoma: Case Report and Systematic Literature Review.
Plurihormonal adenomas (PHAs) represent 10%-15% of all functioning pituitary adenomas. The most frequent hormonal associations are with prolactin and growth hormone (GH). Here we describe a rare case of functional adrenocorticotropic hormone (ACTH) and GH microadenoma and report our findings from a systematic literature review of PHA. ⋯ This is an additional case to the 20 previously reported cases of ACTH-GH PHA. Awareness of this relatively rare entity is clinically relevant. The cytogenesis of ACTH-GH PHA remains a matter of debate, and several hypotheses have been postulated.

Multicenter Study
Moderate Traumatic Brain Injury: Clinical Characteristics and a Prognostic Model of 12-Month Outcome.
Patients with moderate traumatic brain injury (TBI) often are studied together with patients with severe TBI, even though the expected outcome of the former is better. Therefore, we aimed to describe patient characteristics and 12-month outcomes, and to develop a prognostic model based on admission data, specifically for patients with moderate TBI. ⋯ Patients with moderate TBI exhibit characteristics of significant brain injury. Although few patients died or experienced severe disability, 44% did not experience good recovery, indicating that follow-up is needed. The model is a first step in development of prognostic models for moderate TBI that are valid across centers.

Multistage "Hybrid" (Open and Endovascular) Surgical Treatment of Vertebral Artery-Thrombosed Giant Aneurysm by Trapping and Thrombectomy.
Surgical treatment of vertebral artery (VA)-thrombosed giant aneurysms requires achieving both obliteration of the parent artery to prevent bleeding and dome thrombectomy to relieve the brain stem from mass effect. To secure both proximal and distal control of complex VA aneurysms, the contralateral approach to the aneurysm might be a useful alternative, as previously described. We successfully treated a case of VA-thrombosed giant aneurysm in a new, original way by combining craniotomy (ipsilateral and contralateral) and the endovascular technique. ⋯ Based on pathologic and surgical anatomical characteristics, a combination of an endovascular procedure with 2-staged craniotomy for complete trapping, thrombectomy, and vasa vasorum obliteration could be considered a feasible way to treat VA-thrombosed giant aneurysms located ventral to the brain stem and have their distal neck portions/patent vessel beyond the midline toward the contralateral side.

Spontaneous Intraventricular Tension Pneumocephalus: Case Report and Review of the Literature.
Intracranial pneumocephalus is a well-known clinical entity most frequently caused by trauma and intracranial surgery. A less frequent cause of intracranial pneumocephalus is spontaneous pneumocephalus. Spontaneous pneumocephalus can have an intraventricular extension, causing tension intraventricular pneumocephalus. ⋯ This case demonstrates an unusual presentation of spontaneous intraventricular tension pneumocephalus necessitating ventriculostomy in addition to the traditional repair of a cerebrospinal fluid fistula.
