Preoperative diagnosis of a ruptured intracranial dermoid cyst by computerized tomography

Case report

Restricted access

✓ A case of ruptured intracranial dermoid cyst in the right middle fossa is reported. A definitive diagnosis of the lesion and the fact that it had ruptured was made possible by specific computerized tomographic findings. The findings were confirmed at surgery.
