[A case of posttraumatic forehead cavernous angioma].

Cavernous angiomas of the bone are rare tumors. Skull cavernomas are even less frequent. Most cavernous angiomas of the bone are congenital tumors. In a review of the literature, we found only one case report of de novo generation of a skull cavernous angioma. We present a case of a 25-year-old woman who had experienced a head injury, and 7 years later exhibited a skull tumor at the exact region of the injury. We performed tumor resection and cranioplasty. Follow-up examinations revealed no recurrence or neurological defects. Pathological findings showed a cavernous angioma-like lesion with some atypical details. We finally diagnosed the lesion as a de novo cavernous angioma. Our case suggests that fine injury may result in de novo generation of bone cavernomas.
