Review Case Reports
Syringomyelia caused by traumatic intracranial hypotension: a case report and literature review.
Syringomyelia due to intracranial hypotension is rarely described. As a consequence, intracranial hypotension is less recognized as a potential cause of syringomyelia or mistaken with Chiari type 1 malformation. The pathogeny is poorly understood, and we lack diagnostic and therapeutic strategies for this particular setting. ⋯ Syringomyelia can be a consequence of long-term progression of intracranial hypotension, which must be differentiated from Chiari type 1 malformation. In our case, resolution was achieved by detecting and closing the CSF leak causing the intracranial hypotension. Reports of similar cases are necessary to understand the origin of CSF leak in traumatic intracranial hypotension and assess the best therapeutic strategy.

Review Case Reports
Treatment of Penetrating Nonmissile Traumatic Brain Injury. Case Series and Review of the Literature.
Penetrating traumatic brain injuries (TBIs), with the exception of gunshot wounds, are relatively rare occurrences and affect all ages. Clinical presentation varies depending on the mechanism of the injury. Prompt surgical treatment is often indicated and is influenced by patient clinical examination, anatomic trajectory, and the penetrating object's size, shape, and velocity. ⋯ Surgery in penetrating TBI is the treatment of choice. Our cases demonstrate how certain principles applied to individual patient scenarios may optimize clinical results. Severity of the injury and operative approach are among the most important considerations to achieve the best patient outcomes.

Hepatocellular carcinoma (HCC) frequently metastasizes to the spine. The impact of medical and/or surgical intervention on overall survival has been examined in a limited number of clinical studies, and herein we systematically review these data. ⋯ Patients diagnosed with HCC spinal metastasis have a 10.6-month overall survival. Further analysis of patients in prospective controlled trials will be essential to the development of treatment algorithms for these patients in the future.

Marginal zone B-cell lymphoma of the meninges is a rare pathologic subtype of central nervous system lymphoma that can mimic the radiologic appearance of meningioma. ⋯ Although rare, marginal zone B-cell lymphoma must be considered in the differential diagnosis of an extra-axial enhancing mass. We review the contemporary literature and discuss preoperative radiologic differentiation of these 2 very different histopathologies.
