title: Congenital fourth nerve palsy and occult cranium bifidum.
abstract: A 6-year-old girl had paresis of the fourth cranial nerve since infancy. Computed tomography and magnetic resonance imaging revealed occult cranium bifidum with elevation of the straight sinus and tentorium, an abnormal tectal configuration, and a mass in the posterior fossa. Surgical resection revealed that the mass consisted of adipose and fibrous connective tissue. This patient further illustrates that congenital fourth cranial nerve palsy is associated in rare instances with anomalies of the brainstem and adjacent structures.
