Subarachnoid hemorrhage (SAH) is associated with high morbidity. Among all complications, infections, in particular if hospital acquired, could represent an important cause of death in patients with SAH. The aim of this study was to describe infectious complications in patients with SAH and to evaluate their impact on outcome. ⋯ Infections in patients with SAH are prevalent, especially pneumonia. Septic shock is associated with a poor neurologic outcome in this group of patients.

Case Reports
Rare Tumor-to-Tumor Metastases involving Lung Adenocarcinoma to Petroclival Meningiomas.
Lung carcinoma metastasizing to a skull base meningioma remains an extremely rare phenomenon, with only 3 studies reported. Furthermore, no documented cases have been reported in the petroclival region. Thus, we have presented the first 2 cases of tumor-to-tumor metastasis (TTM) in which a petroclival lesion, initially thought to be purely meningioma, was also found to contain metastatic lung adenocarcinoma. ⋯ Skull base TTM is a rare entity for which no specific management guidelines have been created. Therefore, even if the imaging characteristics suggest a more benign process, skull base TTM should remain high on the differential diagnosis for patients with a known primary cancer and new-onset, rapidly progressive, neurologic deficits. Close clinical follow-up with short-interval repeat imaging in this subset of patients might prevent misdiagnosis and facilitate prompt treatment.

A 41-year-old female with a history of chronic hypoparathyroidism with Fahr syndrome presented with complaints of weakness and muscle spasticity. Brain imaging demonstrated diffuse intracranial calcifications. ⋯ The patient underwent a multilevel posterior cervical decompression and fusion. Postoperatively, the patient had noted improvement in her upper and lower extremity strength and spasticity. This illustrative case demonstrates rare clinical and radiographic neurologic sequelae of long-standing hypoparathyroidism.

Lumbar burst fractures (complete or incomplete) of L5 have a low incidence, accounting for 1.2% of all spinal burst fractures. Treatment for these fractures remains controversial. Decompression of neural elements and stabilization of the spine to preserve lordosis and avoid kyphotic deformity are recommended when a patient has a neurological deficit and an unstable fracture. Otherwise, the fracture could be managed conservatively. ⋯ Our unilateral biportal endoscopy technique for L5 incomplete burst fractures offers the capability to perform enough decompression of neural elements and assist other procedure-related maneuvers under direct endoscopic visualization. This technique could be considered another minimally invasive spine surgery option for treating selected patients with L5 incomplete burst fractures.

Previous studies compared outcomes of intracranial meningioma surgery in octogenarians with outcomes in younger patients without accounting for different tumor locations and sizes. The aim of the current study was to evaluate outcomes of intracranial meningioma surgery in octogenarians taking into account patient preoperative status and comorbidities as well as tumor properties. ⋯ This study found no excess mortality or morbidity in octogenarians compared with younger patients. The American Society of Anesthesiologists score rather than age is a significant risk factor for overall morbidity and mortality following intracranial meningioma surgery in octogenarians.
