The usual small apical pneumothorax has been previously described as being typified on chest radiographs by a pencil-thin white line that represents the retracted visceral pleura. Occasionally the apical visceral pleura can become thickened, known as the apical cap, which leads to a variant presentation of apical pneumothorax. To our knowledge, this variant presentation has never been described in the literature, and should improve the detection of apical pneumothorax.
通常的小尖顶气胸在之前的描述中，在胸部X光片上典型表现为一条铅笔细的白线，代表收缩的脏层胸膜。偶尔，尖顶脏层胸膜会增厚，称为尖顶帽，这会导致尖顶气胸的一种变异表现。据我们所知，这种变异表现在文献中从未被描述过，并且应该会提高对尖顶气胸的检测。
