“…However, if they have been obtained, for example by the general practitioner in the work-up for cervical pain, then there may be features that are suggestive of CM and SM such as flattened supraoccipital bone and close proximity of the atlas to the skull (Figures 1 , 2 ). In the instance of severe SM there may be widening of the cervical spinal canal and remodeling and scalloping of the vertebrae due to increased intraspinal pressure ( 93 ) (Figure 2 ). Dynamic (flexion and extension) atlantoaxial radiographs may be indicted to assess stability of the atlantoaxial joint especially if a foramen magnum decompression is planned (Figure 3 ).…”

Clinical Application of Diagnostic Imaging of Chiari-Like Malformation and Syringomyelia

Chiari-like malformation (CM) and syringomyelia (SM) is a frequent diagnosis in predisposed brachycephalic toy breeds since increased availability of MRI. However, the relevance of that MRI diagnosis has been questioned as CM, defined as identification of a cerebellar herniation, is ubiquitous in some breeds and SM can be asymptomatic. This article reviews the current knowledge of neuroanatomical changes in symptomatic CM and SM and diagnostic imaging modalities used for the clinical diagnosis of CM-pain or myelopathy related to SM. Although often compared to Chiari type I malformation in humans, canine CM-pain and SM is more comparable to complex craniosynostosis syndromes (i.e., premature fusion of multiple skull sutures) characterized by a short skull (cranial) base, rostrotentorial crowding with rostral forebrain flattening, small, and ventrally orientated olfactory bulbs, displacement of the neural tissue to give increased height of the cranium and further reduction of the functional caudotentorial space with hindbrain herniation. MRI may further reveal changes suggesting raised intracranial pressure such as loss of sulci definition in conjunction with ventriculomegaly. In addition to these brachycephalic changes, dogs with SM are more likely to have craniocervical junction abnormalities including rostral displacement of the axis and atlas with increased odontoid angulation causing craniospinal junction deformation and medulla oblongata elevation. Symptomatic SM is diagnosed on the basis of signs of myelopathy and presence of a large syrinx that is consistent with the neuro-localization. The imaging protocol should establish the longitudinal and transverse extent of the spinal cord involvement by the syrinx. Phantom scratching and cervicotorticollis are associated with large mid-cervical syringes that extend to the superficial dorsal horn. If the cause of CSF channel disruption and syringomyelia is not revealed by anatomical MRI then other imaging modalities may be appropriate with radiography or CT for any associated vertebral abnormalities.

“…In our case, we identify how a spinal pathology which is causing the symptom of a backache can lead to a rare dermatologic condition. Lumbar spine disc bulge is a common clinical condition which can cause severe lower back pain [ 6 ]. The treatment algorithm that is usually followed for disc bulge/prolapse is to start with oral or topical analgesia, along with physiotherapy; if that does not help, it is followed by a transforaminal nerve block injection (in nerve root compression cases).…”

Background: The oblique lumbar examination has been carried out. The position of object isn't object angle at 45° to the image receptor, but only estimate it. It caused not optimal image of scottie dog sign and spondylolysis (pressure in pars interarticularis). Therefore, an examination aid is needed to make it easier to obtain the position of the oblique lumbar object.Methods: This research design is a RnD study with the ADDIE model which is carried out with five stages, namely analysis, design, development, implementation, and evaluation. The data is carried out by observing, designing, testing, and analyzing whether there are artifacts.Results: An oblique lumbar radiographic examination fixation aid was produced from acrylic material with a thickness of 5 mm. Acrylic is shaped like a right-angled triangular prism building which has a longer base measuring 50 cm, width 42 cm, and height 25 cm. A rectangular base with a length of 50 cm is pressed against the patient's body so that the supporting part of the angled triangle that supports the patient's lumbar region or the patient's body does not shift during an oblique lumbar radiography examination. This tool has a mass dimension of 2.5kg.Conclusion: The design of the oblique lumbar radiographic examination fixation tool resembles a right-angled triangular prism with one side tilted at a 45 degree angle to adjust the position of the object so that it can obtain a good view of the Scottie dog sign to show part of the pars interarticularis.

Signs of Nature in Spine Radiology

Abstract: As medical science developed over time, we have relied on natural imagery to help us recognise and remember things. In this review article, we will be discussing some radiological signs named because of their resemblance to the occurrences in the natural world.
