A case of basilar impression complicated with left frontal meningioma.

METHODS

A 75-year-old baikarian woman was admitted to our hospital for treatment of seizures. From the results of neurological and radiological examination, a left frontal meningioma was suspected and the patient was referred to our department for neurosurgical intervention. At admission, the MRI showed a basilar impression accompanied by Klippel-Feil syndrome of C4/5/6/7, but neurological symptoms of basilar impression were absent. Subsequently, the tumor was resected via the left frontal approach using microsurgical technique. Histological examination disclosed fibroblastic meningioma.

CONCLUSIONS

The coincidence of basilar impression with a brain tumor is a relatively rare occurrence. There are a few reports about craniovertebral junction anomaly including basilar impression associated with spinal or cerebral tumor. This time, we present an interesting combined case of BI and Klippel-Feil syndrome associated with left frontal meningioma.
