Cerebellar abscess induced by a contiguous dermal sinus is a rare event. In a large series of acute posterior fossa abscedation, otogenic suppuration is the cause in 93% of the cases, while hematogenous infection is infrequent, probably because of the relatively weak bloodflow in this part of the central nervous system. The authors present an occipital dermal sinus and dermoid cyst revealed by a cerebellar abscess. The literature is reviewed briefly, treatment and prophylactic measures are discussed.

The results of a retrospective analysis of a series of 73 polytraumatised patients with severe head injuries are presented. The neurological outcome has been less favourable in cases with early osteosynthesis of peripheral fractures compared to cases in which such operations had been delayed. Therefore it seems advisable to postpone the non-vital operative treatment of osteoarticular lesions until stabilisation of the cerebral and vegetative situation.
