MRI findings in the young infant with brainstem disconnection and extracerebral features. Report of one case and review of the literature.

We present the young infant with the extremely rare brain abnormality-brainstem disconnection. Additionally, several extracerebral abnormalities were diagnosed: bilateral anotia, micrognatia, hypertelorism, scoliosis, ribs and vertebral anomalies. MR brain examination precisely demonstrated absence of the pons, with disruption between midbrain and hypoplastic medulla oblongata. The thin strands connecting the medulla with the midbrain and medulla with both cerebellar hemispheres were revealed. The large hamartoma of the tuber cinereum was found. In this study we review case reports published previously.
