Surgical management of skull base and spinal chordomas: A case series with comprehensive review of the literature.

Background: Chordomas are rare, slow growing, locally aggressive malignant bone tumors that arise from remnants of the embryonic notochord with variable presenting symptoms depending on tumor location.

Methods: All patients with craniospinal chordoma managed at our institution between 1982 and 2023 were retrospectively reviewed. Demographics, tumor characteristics, clinical course and treatment, and long-term neurological and survival outcomes were collected.

Review of Breast Imaging in Transgender and Gender-Diverse Patients: Gender-Affirming Care, Histopathologic Findings, Breast Cancer Risk, and Screening Recommendations.

Gender diversity, especially pertaining to transgender and gender-diverse (TGD) populations, is often stigmatized. A small but not insignificant number of adults in the United States identify as TGD, including transgender, nonbinary, and other gender identities than cisgender. Accessing health care remains a significant challenge for TGD individuals because many health care systems adhere to a gender binary model and many TGD individuals experience negative interactions when interfacing with health care.

Surgical management of craniospinal axis malignant peripheral nerve sheath tumors: a single-institution experience and literature review.

Background: Malignant peripheral nerve sheath tumor (MPNST) is an exceedingly rare and aggressive tumor, with limited literature on its management. Herein, we present our series of surgically managed craniospinal MPNSTs, analyze their outcomes, and review the literature.

Methods: We retrospectively reviewed surgically managed primary craniospinal MPNSTs treated at our institution between January 2005 and May 2023.

Clinical diagnostic and radiographic features of recurrent intracranial malignant triton tumor in an adult: illustrative case.

Background: Malignant triton tumors (MTTs) are a rare and aggressive type of malignant peripheral nerve sheath tumor identified histologically by focal rhabdomyoblastic differentiation.

Observations: A 37-year-old female with a prior history of Hodgkin lymphoma presented with acute-onset confusion, cognitive deficits, and weakness. Brain magnetic resonance imaging revealed a hemorrhagic intracranial mass later confirmed to be a malignant triton tumor.

Pediatric brainstem abscess successfully treated with stereotactic aspiration: illustrative case.

Background: Pediatric brainstem abscesses are rare entities that account for 1% of all brain abscesses and, when diagnosed, constitute a neurosurgical emergency.

Observations: A previously healthy 11-year-old male presented with several days of worsening headache, confusion, and ataxia. Brain magnetic resonance imaging (MRI) revealed a midbrain and pons lesion.
