Abstract

OBJECTIVES To describe the clinical and neuroradiological features of basilar impression in patients with osteogenesis imperfecta type IV.

METHODS Four patients with basilar impression were ascertained in a population study of osteogenesis imperfecta. All four had detailed clinical and neuroradiological examination with both CT and MRI of the craniocervical junction andposterior fossa structures.

RESULTS All four showed significant compression of the posterior fossa structures and surgical decompression was performed with relief of symptoms.

CONCLUSION Symptoms of cough headache and trigeminal neuralgia occurring in patients with osteogenesis imperfecta are indications for detailed clinical and neuroradiological investigation to document basilar impression.
