With a patient in the concorde position, lying prone with the head flexed and tilted laterally, higher than the heart, it is possible to use both the occipital transtentorial and infratentorial supracerebellar approaches without changing the patient's position. We report the successful treatment with this combined approach of an arteriovenous malformation in the upper vermis supplied by the superior cerebellar artery.

Concurrent pineoblastoma and unilateral retinoblastoma: a forme fruste of trilateral retinoblastoma?
A 10-month-old boy who presented with strabismus and symptoms of intracranial hypertension was found to have a pineoblastoma and a unilateral ocular retinoblastoma. Despite enucleation of the eye, subtotal removal of the pineoblastoma, and craniospinal axis irradiation, the patient died 6 months later from disseminated intracranial neoplasm. As there was no clinical evidence of bilateral retinoblastoma, this case may represent a forme fruste of the trilateral retinoblastoma complex. The clinicopathological features of this unusual syndrome are reviewed.
