Some sources claim this entity represents 3-6% of pneumothorax in women. In regard of the low incidence of (primary spontaneous, i.e. not due to surgical trauma etc.) pneumothorax in women (about 1/100,000/year), this is a very rare condition. Hence, many basic textbooks don't mention it, and many doctors have never heard of it. However, catamenial pneumothorax is probably under-recognized.
