Case Discussion

This case shows a extensive subdural hemorrhage (SDH) throughout right cerebral convexity with mass effect that erases the cerebral sulci and gyri in addition to compressing the lateral ventricle and the midline shift.

As additional finding to the clinical context osteoma was identified in the paranasal sinuses.

Most osteomas are asymptomatic and are found incidentally when imaging the sinuses either for sinonasal symptoms or for unrelated complaints.
