Wilkinson's syndrome (also known as Sclerotic pedicle sign) is a radiographic term which describes a unilaterally enlarged pedicle opposite a contralateral pars defect. [ 1 ] [ 2 ] The enlarged pedicle may due to stress hypertrophy, and changes may extend into the adjacent lamina and transverse processes.
(The spinal pedicles resemble an owl's eyes and the spinous process resembles an owl's beak.) But when cancer erodes the bony spinal pedicle, the radiographic appearance changes such that now that eye of the owl seems missing or closed, which is called the "winking owl sign". Another common pattern is a "Scottie dog sign" on a spinal X-ray. [61]

A radiologic sign is an objective indication of some medical fact (that is, a medical sign) that is detected by a physician during radiologic examination with medical imaging [1] (for example, via an X-ray, CT scan, MRI scan, or sonographic scan).
The light bulb sign is a radiological finding observed on plain radiographs in the context of posterior shoulder dislocation. [1] It refers to the abnormal, rounded appearance of the humeral head, which resembles a "light bulb," due to internal rotation of the arm following dislocation.
Owl's eye appearance, also known as owl's eye sign, is a pattern used in the medical field to describe cells (or cell attributes) that resemble the shape of an actual owl's eye. Using the techniques of histology and radiology , microscopes and other medical imaging are used to locate this pattern of "owl's eye" shaped cells.
