Abstract
External hydrocephalus (EH) is a recognised sub-type of hydrocephalus associated with macrocephaly in infancy. EH is characterised by the enlargement of subarachnoid spaces (so-called subarachnomegaly) with a normal ventricular system on brain imaging. EH is traditionally considered benign and self-limiting, yet its pathophysiology remains puzzling. Mounting evidence for an association between EH and hydrovenous disorders reshapes our understanding of this condition and its management. To our knowledge, we report the first association between EH and dural arteriovenous fistula (dAVF) in a 17-months-old boy. As dAVF may be a life-threatening condition, early diagnosis and optimal treatment are critical. This case epitomises the intricacies of EH's aetiology and associated conditions requiring careful management. Therefore, we recommend considering MR angiography in EH's workup and long-term follow-up. Our experience supports the ongoing reconsideration of EH's presumed benignity.
期刊介绍:
The British Journal of Neurosurgery is a leading international forum for debate in the field of neurosurgery, publishing original peer-reviewed articles of the highest quality, along with comment and correspondence on all topics of current interest to neurosurgeons worldwide.
Coverage includes all aspects of case assessment and surgical practice, as well as wide-ranging research, with an emphasis on clinical rather than experimental material. Special emphasis is placed on postgraduate education with review articles on basic neurosciences and on the theory behind advances in techniques, investigation and clinical management. All papers are submitted to rigorous and independent peer-review, ensuring the journal’s wide citation and its appearance in the major abstracting and indexing services.
