Ovarian dermoids posses a distinct fibrous capsule which may be recognized radiographically by virtue of the contrasting effect of the greasy dermoid matter and the surrounding peritoneal fat. Part or all of the wall may be outlined in some projections even when the dermoid contents are not radiolucent enough to be recognized as such. Occasionally the wall of a dermoid cyst, heavily calcified or ossified, may be easily recognized radiographicaly.
卵巢皮样囊肿有一层独特的纤维包膜，由于皮样囊肿内油脂物质与周围腹膜脂肪的对比效果，在影像学上可以识别。即使皮样囊肿内容物的放射性不够强而无法直接识别，在某些投照体位下，部分或全部囊壁仍可能显示出来。偶尔，皮样囊肿的囊壁会出现重度钙化或骨化，在影像学上很容易识别。
