ARACHNOID CYSTS Clinical and Surgical Management Ebook PDF download To my knowledge, this is the first textbook in English ever on arachnoid cysts (AC). Considering the fact that AC is the most common intracranial expansive condition in the general population, this absence of comprehensive literature is striking. Most probably it reflects the common attitude shared by many colleagues: that an AC is a congenital,benign condition that does not require attention unless it yields dramatic symptoms.
More often than for other intracranial conditions, relatively little high
level evidence exists on ACs and how we should deal with them.
Unfortunately, the majority of publications on the subject are case
reports or case series with low level of evidence and consequently
little to build recommendations on. However, there are also studies that
have investigated AC related matters in larger cohorts and in a system-
atic fashion. In this book, emphasis is placed on such extensive and sys-
tematic reports when they exist, rather than on reports describing a few
However, if a large collection of case reports point in the same direc-
tion, such evidence cannot be completely dismissed. Less weight must
be put on “experts’ opinions” if they are based only on clinical experi-
ence achieved back in the time when any intracranial procedure was a
risky undertaking, attitudes that have been conveyed to us from previ-
ous generations of colleagues without any questioning of the truth of
the message in the meantime. It is my impression, after having read
hundreds of publications in preparing this book, that this lack of systematically collected evidence in the past has allowed mindsets acquired decades ago to survive and maintain the status of truth, even if the basis of this “wisdom” is very weak, see e.g., Chapter 1, Arachnoid CystsHistorical Perspectives and Controversial Aspects in Volume 1.
