RESUMEN
BACKGROUND: The authors present the only known case of a World Health Organization grade II ectopic meningioma occurring in the infraclavicular brachial plexus, causing pain within the axilla not associated with a primary malignant meningioma of the central nervous system. Peripheral nerve sheath tumors are rare entities, the majority of which are schwannomas or neurofibromas. Ectopic meningiomas only represent 1%-2% of all meningiomas. To date, there is one other published case specifically of a primary ectopic meningioma located in the brachial plexus. OBSERVATIONS: Following the dissection of the left axilla, a dominant rubbery tumor involving the median nerve was encountered. The tumor capsule contained areas of hemorrhage and a soft core with nerve fascicles coursing through, which were not compromised during internal tumor debulking. The tumor lacked a clear pseudocapsule that is characteristically seen in schwannomas. Histopathological studies confirmed an atypical epithelioid neoplasm with elevated numbers of mitotic figures and BAP1 gene deletion. LESSONS: Primary meningiomas arising outside the central nervous system are exceedingly rare. For this unusual higher-grade primary ectopic meningioma located in the distal brachial plexus, surgery with the goal of gross-total resection, adjuvant radiation, additional imaging, and genetics screening were recommended. Close follow-up is warranted. https://thejns.org/doi/10.3171/CASE24226.

INTRODUCTION: Patients with vascular disease have higher mortality rates than age-matched peers and medical management of coexisting diseases may alter these outcomes. We sought to understand factors associated with medication nonadherence in vascular surgery patients at a single University vascular surgery clinic over a 3-month period. MATERIALS AND METHODS: Consecutive vascular surgery patients were surveyed from June to August 2019. The survey included demographic questions, the validated Morisky Medication Adherence Scale, the 4-item Patient Health Questionnaire for Anxiety and Depression scales, and other medication-related questions. Medical and surgical histories were retrospectively collected from charts. Univariate and multivariate analyses were used to compare among high, intermediate, and low adherence. RESULTS: A total of 128 (74%) of 174 patients met study inclusion criteria. On univariate analysis, lower medication adherence was associated with younger age (P = .004), anxiety and depression (P = .001), higher daily pain (P < .001), and patients who believed their medications were less important for treating their vascular disease (P < .001). Adherence was not associated with symptomatic vascular disease, gender, education level, marital status, employment, insurance, or the use of medication usage reminders. Multivariate analysis significantly predicted high adherence relative to low adherence with 5-year increase in age (odds ratio [OR] = 1.252, P = .021) and low adherence relative to high adherence with greater perceived pain (OR = 0.839, P = .016). CONCLUSIONS: Younger age and high level of pain were associated with lower medication adherence. Informing patients of the importance of prescribed medication and addressing anxiety or depression symptoms may improve adherence.
