Discuss the most common radiological signs inspired by animals. Explain each of the signs’ backgrounds,
uses and radiological applications. Illustrate the zoological signs through diagrams and real-life cases and using multiple imaging modalities. Geared towards medical students,
and physicians from other specialties,
to learn and review in a creative way.
signs associated with diseases are valuable since they provide a great way to remember and distinguish different pathologies.
They provide a physician confidence in recognizing a pathology in order to narrow down the differential diagnosis.
Many radiological signs are named by the things they resemble including inanimate objects,
and even animals.
Thousands of signs have been presented,
since the first radiological sign was described in 1918.

Findings and procedure details
Many radiological signs are named by the things they resemble which may include inanimate objects,
and even animals.
In this exhibition,
we will discuss and illustrate some of the most common radiological signs of a variety of radiological subspecialties and imaging modalities,
whose name was inspired by their resemblance with a diversity of animals.
Let’s get ready for a visual walk through the zoo! Anteater nose sign Calcaneonavicular coalition refers to a fusion between the...
A great number of zoological metaphors have formed part of radiological reports,
including more than the ones just described,
for example: abdominal cocoon sign,
eye of the tiger sign,
manta ray sign,
rat bite and rat tail signs,
amongst many others; and there is room for more.
Description and creativity to develop pattern recognition is vital for radiologists and so,
the possibilities are endless for metaphoric signs in radiology.
