Аннотация
BACKGROUND: Subdural osteomas are benign neoplasms that are rarely encountered. We report the case of a 64‑year‑old female patient with a left temporal subdural osteoma.
CASE DESCRIPTION: The patient presented with intermittent dizziness that first began two years earlier. Non-contrast computed tomography revealed a densely calcified left temporal extra-axial mass. Magnetic resonance imaging of the lesion revealed signal loss on T1-weighted and T2-weighted images and non-enhancement on Gadolinium enhanced T1-weighted images, and diffusion-weighted and ADC images demonstrated reduced values attributed to calcium-induced signal loss. Histologically, the lesion predominantly consisted of lamellar bone without bone marrow elements. The patient underwent stereotactic magnetic resonance imaging-guided neurosurgical resection and recovered without complication.
CONCLUSIONS: Subdural osteomas may not be enhanced on magnetic resonance imaging. Surgical tumourectomy can be considered for symptomatic patients with subdural osteomas.
