Purpose: Neurosyphilis can mimic different diseases, not only in its clinical presentation but also on imaging. Treponema pallidum is also known as the "great imitator." Having an ultimate diagnosis of neurosyphilis is quite critical as this can affect management drastically. Herein, we discuss the case of a 69-year-old female who was treated for neurosyphilis, while having an atypical imaging finding of anterior temporal lobe enhancement that simulated an infection with herpes simplex virus (HSV); we also review the available literature on different imaging findings in both the early and late stages of the disease. Methods: We performed a literature search using the new PubMed in June 2021. The terms "neurosyphilis", "MRI", and "neuroimaging" were used either alone or in combination with "early neurosyphilis" or "late neurosyphilis". Data on neurosyphilis and imaging findings was mainly derived from review articles, cohort studies, case series, and individual reports. Conclusion: Neurosyphilis can present with an extensive variation and different patterns on the MRI, and clinicians must be aware of the wide variety in radiological presentations. Anterior temporal lobe involvement is a rare presentation and requires evaluating for neurosyphilis to prevent a missed diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Background and Purpose: Chronic subdural hematomas (cSDH) are subdural collection of blood for which the current treatment option remains as surgical evacuation due to recurring focal inflammation and angiogenesis. An adjunctive therapeutic intervention is endovascular embolization of the middle meningeal artery (MMA) to cease the prolific cycle of angiogenesis. Few investigations have been made into the indications of this treatment modality regarding the intervention timeline and hematoma size for non-surgical candidates with acute-on-chronic subdural hematomas., Methods: We examined the clinical outcomes of 19 patients with 31 acute-on-chronic SDHs undergone MMA embolization and highlighted preliminary trends in radiological and morbidity outcomes., Results: Primary outcomes identified a 57.6% success rate for MMA embolization of acute-on-chronic SDHs defined as significantly reduced hematoma size (i.e. >50%) without recurring bleeds, peri-procedural complications, post-procedural neurological deficits, and need for post-procedural surgical evacuation. Subgroup analysis demonstrated a success rate of 90.9% in patients undergone embolization after a minimum 3-week delay from initial CT head study compared to 33.3% with early intervention as well as a success rate of 75% in patients presenting with a large (i.e. >10 mm) SDH compared to 30% for small SDH., Conclusion: Our preliminary data in this retrospective cohort study demonstrates significantly improved outcomes of MMA embolization in patients presenting with large (>10 mm) acute-on-chronic SDHs and in patients undergone embolization after >3 weeks from initial CT head and symptomatic presentation., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)
