Guillain-Barré syndrome (GBS) is a rare but well-documented cause of paralysis, often occurring after infection. Few cases have been reported in association with spinal cord injury (SCI), which masks the characteristic ascending paralysis. To our knowledge, this is the first reported case of confirmed GBS during the clinical course of thoracic paraplegia due to a gunshot wound (GSW). ⋯ The differential diagnosis for new-onset weakness in patients with GSW-induced SCI is complicated by the inability to obtain magnetic resonance imaging. This unique case of GBS in a patient with T4 paraplegia highlights the importance of obtaining a thorough history and using diagnostic tools to explore possibilities beyond surgery.

In recent decades there has been a significant expansion of neurosurgical capabilities in low- and middle-income countries, particularly in Southeast Asia. Despite these developments, little is known about the structure and quality of local neurosurgical training paradigms. ⋯ Although the unmet burden of neurosurgical disease remains high, local training programs are devoting significant efforts to provide a sustainable solution to the problem of neurosurgical workforce. High-income country institutions should partner with global colleagues to ensure high-quality neurosurgical care for all people regardless of location and income.

Osteosarcoma is a common malignant bone tumor that occurs in children or adolescents but rarely in the skull. Epidermoid cysts, also known as cholesteatomas, represent approximately 0.2%-1.8% of all intracranial tumors. The occurrence of osteosarcoma with an epidermoid cyst is extremely rare. ⋯ Osteosarcomas and epidermoid cysts should be completely resected to prevent tumor recurrence and aseptic meningitis. Postoperative osteosarcoma treatment should include radiotherapy and chemotherapy to improve the survival rate of patients. It is hoped that this report will help clinicians in diagnosis and treatment of patients with similar conditions.

Solitary plasmacytoma of bone (SPB) is a rare malignancy of localized osseous lesion consisting of neoplastic monoclonal plasma cells. Recommended treatment of SPB includes a combination of surgery and radiation therapy. We present a rare case of SPB lesion in the atlas requiring surgical resection, followed by restoration of atlas stability with a custom 3-dimensional-printed (3DP) patient-specific implant (PSI). ⋯ No consensus on the appropriate surgical approaches and perioperative strategies for spinal SPB exists. Surgical intervention is recommended when vertebral instability is evident, followed by radiation therapy to minimize local recurrence and/or progression to multiple myeloma. The use of 3D modeling for preoperative planning improves intraoperative accuracy and avoids iatrogenic injuries to vital anatomic structures. Customized 3DP-PSI to restore atlas stability is an effective option for the treatment of spinal SPBs.

There is a lack of consensus regarding diagnosis, timing, and method of intervention for progressive enhancement on surveillance imaging after stereotactic radiosurgery (SRS) treatment of brain metastases. We sought to characterize current practices among neurosurgeons in identifying and treating infield tumor recurrence (TR) or radiation necrosis (RN) after SRS for brain metastases. ⋯ Our survey of practicing neurosurgeons highlights areas of controversy in distinguishing between TR and RN and preferred management of suspected RN.
