Abstract

Background: The aim of the present case report is to describe an unusual complication of foramen magnum decompression (FMD) for the Chiari 1 hindbrain malformation and its successful management with non-operative measures. Methods: A 2-year-old girl with the Chiari 1 malformation underwent FMD, including suboccipital craniotomy, C1 laminectomy and durotomy without opening the arachnoid. Results: After initial postoperative improvement, the patient deteriorated, developing subdural hygromas and hydrocephalus. These were treated successfully with observation and acetazolamide. Conclusions: Subdural hygromas may complicate FMD. A slit valve opening in the arachnoid might be part of the pathophysiology. While surgical intervention may be necessary in some circumstances, non-operative measures may be effective as well.
