Exploring Intraosseous Meningiomas: Case Series and Literature Insights from a Tertiary Care Hospital in Pakistan

Abstract

This study is a retrospective case series exploring the clinical and radiological parameters with surgical approach and its outcome for Intraosseous Meningioma (IM), a rare benign tumor primarily affecting the craniofacial bones. It was conducted at the Department of Neurosurgery Unit-III, Punjab Institute of Neurosciences (PINS) from January 2022 to December 2024. The study included five surgically treated patients through non-probability consecutive sampling. A descriptive analysis was done for clinical-radiological and outcome-based variables. The cohort included four females and one male, with a mean age of 34±15.77 years. Most presented with painless progressive swelling, predominantly in the frontal and parietal bones. CT scan consistently revealed hyperostosis and MRI dural enhancement. All patients underwent craniectomy and complete excision, with four requiring cranioplasty. Histopathological analysis confirmed WHO Grade I Meningioma in all cases. No postoperative complications or recurrences were noted during 3-6 months of follow-up. The study underscores the importance of early diagnosis and complete surgical resection in managing IM and contributes to the limited existing literature.
