“…Descriptions of the term are almost as imaginative as the names of some of the more colorful examples. Imaging signs have been described as the "spices of medicine… savored by the diagnostic gourmet" [3], a "secret language" [3], and a radiologist's stock in trade [12]. Hundreds of imaging signs play a unique role in diagnostic expression by describing radiological observations through the use of eponyms, metaphors, and sometimes, esoteric or outdated references.…”

“…The "Signs in Imaging" series in Radiology [6] constitutes a collection of 118 articles, published from 1999 to 2008, such as "Hawkins sign" [7] and "enlargement of the hilar periportal space" [8]. We incorporated terms and definitions from 10 review articles [9][10][11][12][13][14][15][16][17][18] and from online references such as CHORUS [19,20], the Interactive Atlas of Signs in Musculoskeletal Radiology [21], Medcyclopedia [22], Radiopaedia [23], and RadsWiki [24]. These resources were selected as they represent the core resources that itemize radiology signs.…”

Imaging signs form an important part of the language of radiology, but are not represented in established lexicons. We sought to incorporate imaging signs into RSNA's RadLex® ontology of radiology terms. Names of imaging signs and their definitions were culled from books, journal articles, dictionaries, and biomedical web sites. Imaging signs were added into RadLex as subclasses of the term "imaging sign," which was defined in RadLex as a subclass of "imaging observation." A total of 743 unique imaging signs were added to RadLex with their 392 synonyms to yield a total of 1,135 new terms. All included definitions and related RadLex terms, including imaging modality, anatomy, and disorder, when appropriate. The information will allow RadLex users to identify imaging signs by modality (e.g., ultrasound signs) and to find all signs related to specific pathophysiology. The addition of imaging signs to RadLex augments its use to index the radiology literature, create and interpret clinical radiology reports, and retrieve relevant cases and images.

“…Both stag horn and spiked calculi were seen in this case. Urinary tract stones composed of calcium oxalate dihydrate can assume a spiked configuration, resembling a child's toy jack [7]. McDonald and McClellan classified crossed ectopic kidney into four types: crossed renal ectopia with fusion (85%), crossed renal ectopia without fusion (10%), solitary crossed renal ectopia, and bilaterally crossed renal ectopia [8].…”

“…renal embryological ascending path; nevertheless, most are localized in a low position at the level of the third to fifth lumbar vertebrae, because the isthmus prevents them from ascending beyond the inferior mesenteric artery. 1,6 The fusion also prevents normal renal rotation, leaving the lower poles facing medially, with the renal pelvis located anteriorly and a high ureteral insertion. 1,6 The ureters usually cross in front of the isthmus as they descend towards the bladder.…”

Horseshoe kidney (HSK) is the most common renal fusion anomaly, with a prevalence of 0.25% among the general population. It consists of kidney fusion across the midline. HSK can be present as an isolated condition in 30%, but there is a wide variety of associated abnormalities. The most frequent include ureteropelvic obstruction, lithiasis and infections. There is also a higher risk of kidney lesions in trauma and an increased incidence of malignancies. Awareness of embryology and anatomy is essential to assess and understand the complications affecting HSK. CT is an excellent method for identification of its main findings.Horseshoe kidney (HSK) represents one of the most frequent renal malformations, with an incidence of 0.25% among the general population, being twice as frequent in males.1-3 It consists of a fusion of the kidneys across the midline, joined by an isthmus of renal parenchyma or fibrous tissue. 1,3 There are no known genetic determinant factors, although it has been described on identical twins and siblings of the same family. 4CT TECHNIQUE Multislice CT allows obtaining images with high spatial and temporal resolution over multiple planes and threedimensional reconstructions of high quality, and therefore the technique of choice for evaluation of urinary tract anatomy and pathologies associated with HSK.
