title: Clinics in diagnostic imaging (6).
abstract: A nine-month-old Chinese girl presented with a large buttock mass. Serum alpha-fetoprotein level was elevated. Plain radiographs, computerised tomography and magnetic resonance imaging demonstrated a solid heterogeneous presacral mass. A sacrococcygeal teratoma was excised using the abdominoperineal approach. The patient responded well to multiagent chemotherapy. The features of this tumour are discussed, with emphasis on the role of imaging.
