Meningiomas arise from the malignant transformation of meningeal cells in the arachnoid or pia mater, characterized by slow growth and typically localized presentation. While most are benign, a minority exhibit malignancy. Spinal meningiomas, a common subtype, primarily manifest as intradural, extramedullary tumors, constituting a significant portion of spinal neoplasms. They predominantly affect middle-aged to elderly individuals, with a higher incidence among women. 


Early symptoms may be subtle, progressing to manifest spinal cord compression symptoms such as pain, limb weakness, and urinary or fecal dysfunction. In cases of intracranial invasion, symptoms like severe headache and blurred vision may occur. Timely surgical intervention is crucial to mitigate risks of paralysis and dysfunction, with prognosis generally favorable post-resection. Surgical techniques vary based on tumor location, with approaches tailored to minimize spinal cord manipulation.


Postoperative care is paramount, emphasizing meticulous wound management to prevent infection and optimize healing. Various studies have explored innovative surgical approaches and postoperative protocols to enhance patient outcomes. A recent analysis of postoperative meningioma cases aimed to provide insights into optimizing incision healing and infection prevention, contributing to ongoing advancements in postoperative care practices.
