Asymptomatic posterior fossa subdural effusion

ABSTRACT

Though subdural effusion is very common supratentorially; a similar occurrence in the posterior fossa is rather unusual with all the cases of posterior fossa subdural collection reported in the literature being symptomatic, mandating some form of intervention. An asymptomatic posterior fossa collection is not reported before as per the authors' review of the literature. The authors report a 5-year-old child was found to have a posterior fossa subdural collection postoperatively after a posterior fossa surgery. As the child was asymptomatic, the parents were reassured and the child was managed conservatively. Posterior fossa subdural effusion is very rare condition mandating some form of surgical intervention. It can occasionally be asymptomatic, in which case a conservative approach can be followed. A regular follow-up is recommended to detect any neurological deterioration, however
