We report on 8 Brazilian patients with the oculo-auriculo-vertebral (OAV) complex with associated uncommon anomalies of hydrocephalus, porencephalic cyst, hand abnormalities, terminal/paraxial hemimelia, Klippel-Feil anomaly, Rokitansky sequence, fibrous dysplasia, and dextrocardia. Our patients show that in some instances a definite diagnosis can be difficult within the wide clinical picture of the OAV complex.
