Aggressive cranial vault decompression for cranial hyperostosis: technical case report of two cases.

OBJECTIVE AND IMPORTANCE

Camurati-Engelmann's disease, also known as progressive diaphysial dysplasia, is a disorder of the bone metabolism. Neurological manifestations of progressive diaphysial dysplasia include cranial nerve dysfunction, generalized weakness, cerebellar herniation, and increased intracranial pressure. In the past, surgical intervention has been of limited and temporary benefit. We present two patients with cranial hyperostosis secondary to Camurati-Engelmann's disease who were treated successfully with a single surgery involving a combination of multiple craniotomies for cranial vault decompression.

CLINICAL PRESENTATION

Two patients presented with signs and symptoms of increased intracranial pressure secondary to Camurati-Engelmann's syndrome. Radiological workup revealed marked cranial hyperostosis.

INTERVENTION

The patients underwent aggressive cranial vault decompression. Multiple craniotomies were performed, and the inner table was then drilled down until the bone was 1 cm thick.

CONCLUSION

Effective surgical options are needed for clinically significant cranial hyperostosis. In an effort to further define operative management in these patients, we describe a single, aggressive surgical procedure that may be used for successful cranial decompression.
