There are several well-known diagnostic signs in radiology such as scotty dog, dog ears, moon sign and etc. These signs are resulted from assuming a view of nature pattern; inferior perspectives; on radiography, sonography, CT scan and MRI images. Sometimes, the pathology or abnormality of an organ may present an appearance very similar to a natural pattern in medical images. Some of them are so common and can be considered as a sign of a specific pathology or abnormality, which is a great help for easier diagnosis. Fibroids are one of the most common pathologies that can produce similar and frequent appearances on hysterosalpingography (HSG). After investigating more than 5,000 HSG images collected by Dr. Shahrzad and the Royan Imaging Center, we found some new diagnostic signs which were commonly repeated in hysterograms of infertile women. We try to introduce theses signs in this lecture.
