    Abstract:
    INTRODUCTION: Meningiomas located in the posterior fossa and involving the sinodural angle at the junction of the transverse and sigmoid sinuses are uncommon and present unique challenges due to their complex anatomical location. Despite their distinctive features, they are frequently categorized with tentorial meningiomas in the literature. MATERIALS AND METHODS: This retrospective study conducted at a tertiary care center involved 64 patients with sinodural meningiomas who underwent surgical treatment between 2010 and 2023. The analysis covered demographics, clinical presentation, radiological characteristics, surgical approaches, histopathological findings, and outcomes. RESULTS: The cohort predominantly comprised females (83 %) with a mean age of 47.64 years. Headache (92.2 %) and gait disturbances (62.5 %) were the most common presenting symptoms. Preoperative imaging showed sinus involvement in 57.8 % of cases, predominating Sindou's type 1 and type 6. Gross total resection (Simpson grades 1-2) was achieved in 40.6 % of cases. Postoperative complications included pseudomeningocele (9.4 %), especially in patients with hydrocephalus. CONCLUSION: Sinodural meningiomas represent a distinct subset of posterior fossa tumors, necessitating meticulous preoperative planning and intraoperative decision-making regarding sinus management. The study underscores the importance of individualized surgical strategies and highlights the role of radiosurgery in managing residual disease effectively.
