Case Reports
Neoplastic cerebral aneurysm from metastatic lung adenocarcinoma with neuroendocrine features.
Neoplastic cerebral aneurysms are exceedingly rare. We describe a case of a ruptured, distal middle cerebral artery aneurysm as the presenting symptom leading to the identification of metastatic lung cancer. ⋯ Neoplastic cerebral aneurysms are rare, and there are insufficient data to support specific guidelines for management. This case is novel as the patient received adjuvant stereotactic radiosurgery to the operative bed, as well as systemic chemotherapy, and has maintained good functional status as of last follow-up at 6 months.

Distal middle cerebral artery aneurysm (DMCAAn) is rare, and the clinical features and the etiology are not well understood. Segmental artery mediolysis (SAM) is a pathologic entity that affects the media of the muscular artery and can cause arterial dissection and a hemorrhagic event. Subarachnoid hemorrhage (SAH) due to SAM in the vertebral artery has been documented. However, SAH from a ruptured DMCAAn due to SAM has not yet been described. ⋯ Our case suggests that SAM can also occur in the middle cerebral artery and result in DMCAAn.

Microscopic anterior cervical foraminotomy (MACF) is a surgical technique for unilateral cervical radiculopathy that preserves segmental motion and avoids adjacent segmental degeneration, but little is known of its long-term outcomes. ⋯ Although some radiologic results have shortcomings, the results of this study suggest that MACF has favorable long-term outcomes.

Previous studies have indicated traumatic brain injury (TBI) as a risk factor for stroke and myocardial injury. Whether TBI increases new onset of major adverse cardiovascular and cerebrovascular events (MACCE) is not well established. ⋯ Our results showed that patients with TBI have a significantly greater risk of MACCE than the control group. We hope this information will remind critical-care physicians and neurosurgeons to keep in mind the long-term effects of TBI on MACCE.

Spine pathology is a common reason for admission to neurosurgical units in low- and middle-income countries (LMICs) and can have high morbidity rates from lack of specialized institutes. However, good surgical outcomes and quality-of-life scores have been reported in LMICs. This study details the complication rates and predictive factors from spine surgery at a large hospital in Cambodia, aiming to identify high-risk patients to improve surgeon understanding of these complications for improved pre-operative planning and patient counseling. ⋯ Many factors play a role in spine surgery complications in LMICs, including limited access to intra-operative technology, low follow-up rates, and minimal physiotherapy and rehabilitation capabilities. Patients with long delays in presentation, American Spinal Injury Association grade A injuries, and lumbar-level surgery may be especially susceptible to complications and postoperative morbidity. Despite this, institutions have reported encouraging spine trauma outcomes, and spine surgeries are becoming more accepted and safe operations in many LMICs.
