Historical ArticleDr. Louise Eisenhardt's personal notes: how she and Dr. Cushing collected data and followed patients.
Dr. Louise Eisenhardt was one of the first neuropathologists and was responsible for the development of tumor diagnosis guidelines. This historical vignette reviews her previously unseen handwritten notes in which she describes methods used by her and Dr. ⋯ Drs. Eisenhardt and Cushing believed "every case was important in adding to our collective knowledge of various types of tumors particularly in relationship to life expectancies and suggesting improvement in surgical treatments." Dr. Eisenhardt's meticulous record keeping allows for insights into the first known outcomes-related tumor registry in neurosurgery.

Multicenter StudyClinical and radiologic outcomes after stereotactic radiosurgery for meningiomas in direct contact with the optic apparatus: an international multicenter study.
Resection of meningiomas in direct contact with the anterior optic apparatus carries risk of injury to the visual pathway. Stereotactic radiosurgery (SRS) offers a minimally invasive alternative. However, its use is limited owing to the risk of radiation-induced optic neuropathy. Few SRS studies have specifically assessed the risks and benefits of treating meningiomas in direct contact with the optic nerve, chiasm, or optic tract. The authors hypothesized that SRS is safe for select patients with meningiomas in direct contact with the anterior optic apparatus. ⋯ In this international multicenter study, the vast majority of patients exhibited tumor control and preservation of visual function when SRS was used to treat meningioma in direct contact with the anterior optic pathways. SRS is a relatively safe treatment modality for select patients with perioptic meningiomas in direct contact with the optic apparatus.

Lessons from the life of Asia's first female neurosurgeon for modern neurosurgical trainees and educators worldwide.
Surgical specialties, and particularly neurosurgery, have historically had and continue to have poor representation of female trainees. This is especially true of South Asia, considering the added social and cultural expectations for women in this region. Yet it was in India, with its difficult history of gender relations, that Asia's first fully qualified female neurosurgeon, Dr. ⋯ Many of the virtues that ensured her success are attributes that continue to be critical for a neurosurgical career. Additionally, the circumstances that helped Kanaka succeed have been recounted as considerations for those working to promote diversity and inclusion. Finally, her life choices and sacrifices are described, which are underexplored but relevant concerns for women in neurosurgery.

Risk of tract recurrence with stereotactic biopsy of brain metastases: an 18-year cancer center experience.
Stereotactic biopsy is increasingly performed on brain metastases (BrMs) as improving cancer outcomes drive aggressive multimodality treatment, including laser interstitial thermal therapy (LITT). However, the tract recurrence (TR) risk is poorly defined in an era defined by focused-irradiation paradigms. As such, the authors aimed to define indications and adjuvant therapies for this procedure and evaluate the BrM-biopsy TR rate. ⋯ In this study the authors identified a nontrivial, higher than previously described rate of BrM-biopsy tract recurrence, which often required additional surgery or radiation and justified close radiographic surveillance. As BrMs are commonly treated with SRS limited to enhancing tumor margins, consideration should be made, in cases lacking CNS-active systemic treatments, to include biopsy tracts in adjuvant radiation plans where feasible.

Facial pain and sensory outcomes following resection of tumors compressing the trigeminal nerve.
Tumors compressing the trigeminal nerve can cause facial pain, numbness, or paresthesias. Limited data exist describing how these symptoms change after resection and what factors predict symptom improvement. The objective of this study was to report trigeminal pain and sensory outcomes after tumor resection and identify factors predicting postoperative symptom improvement. ⋯ Most patients with facial sensory symptoms caused by meningiomas or VSs experienced improvement after resection. Surgery led to immediate and sustained improvement in pain and paresthesias, whereas numbness was slower to improve. Patients with smaller tumors and complete decompression of the trigeminal nerve were more likely to experience improvement in facial pain.
