Implication

Case report demonstrates a primary extracranial sphenoid bone meningioma in a 53-year-old female, highlighting diagnostic features of skull base tumors lacking dural attachment.

Key Points

To describe the clinical presentation, radiological characteristics, and pathological findings of a rare primary extracranial sphenoid bone meningioma with multicompartmental extension.
Evaluated a 53-year-old female presenting with an enlarging left temporal mass using CT, MRI, 3D-CT angiography, and ¹²³I-IMP SPECT imaging.
Performed surgical resection via frontotemporal craniotomy followed by histopathological and immunohistochemical evaluation.
Preoperative imaging showed a multicompartmental sphenoid mass with bone remodeling, homogeneous enhancement, no abnormal vascularity, and absent ¹²³I-IMP SPECT uptake.
Histopathology confirmed a WHO grade 1 transitional meningioma with psammoma bodies and low Ki-67 index infiltrating bone and muscle without dural continuity.
