Abstract
Extradural neoplasms are the most common spinal tumors in small animals. A bilobed appearance of ventral extradural spinal lesions ("gullwing sign") on MRI has been described with various conditions. The objective of this retrospective study was to determine if a "gullwing sign" is more common with certain types of extradural tumors. MRI studies of dogs and cats with extradural spinal neoplasms were reviewed for the presence of a "gullwing sign". Statistical analysis was performed to evaluate a possible relationship between tumor class and the presence of a "gullwing sign". Sixty-six cases were included (5 epithelial, 31 mesenchymal, 4 neuroendocrine, and 26 round cell tumors). A "gullwing sign" was identified in 12 of 66 cases (18.2%) and was significantly more common with round cell neoplasia than other tumor types (P < .001; OR = 28.6, 95% CI [3.4, 241.1]). This information may aid radiologists in prioritizing differential diagnoses for extradural tumors in small animals.
期刊介绍：
Veterinary Radiology & Ultrasound is a bimonthly, international, peer-reviewed, research journal devoted to the fields of veterinary diagnostic imaging and radiation oncology. Established in 1958, it is owned by the American College of Veterinary Radiology and is also the official journal for six affiliate veterinary organizations. Veterinary Radiology & Ultrasound is represented on the International Committee of Medical Journal Editors, World Association of Medical Editors, and Committee on Publication Ethics.
The mission of Veterinary Radiology & Ultrasound is to serve as a leading resource for high quality articles that advance scientific knowledge and standards of clinical practice in the areas of veterinary diagnostic radiology, computed tomography, magnetic resonance imaging, ultrasonography, nuclear imaging, radiation oncology, and interventional radiology. Manuscript types include original investigations, imaging diagnosis reports, review articles, editorials and letters to the Editor. Acceptance criteria include originality, significance, quality, reader interest, composition and adherence to author guidelines.
