Abstract
We report four cases with the rare syndrome of tecto-cerebellar dysraphia with occipital encephalocele. The clinical features seen in these patients included episodic tachypnea and irregular breathing, opsoclonus, ataxia, marked hypotonia of the limbs, coloboma, and polydactyly. All four patients had midline occipital encephalocele. The cranial computed tomography scan showed partial to total agenesis of the vermis with a large communication between cisterna magna and the fourth ventricle. The computed tomography scan also showed partial deficiency of the midbrain tectum. We discuss the clinical and radiological findings and review the literature.
