"Three possible mechanisms for pain are suggested: local effect, referred pain via the trigeminal nerve, and a prostaglandin E-2 mediated mechanism 5. There can be a significant inversely proportional discrepancy between the size of the lesion and the symptoms; do not simply assume because the lesion is small it does not account for the patient's symptoms."
"Some osteomas are large and exophytic. They may be palpable (as is the case with skull vault osteomas) or compress structures, such as the content of the orbit 1-3. Rarely an osteoma may encroach upon the brain, and may even result in erosion of the dura with resultant CSF leak, pneumocephalus or intracranial infection (meningitis, cerebral abscess) 1,2,4."
