![]() ![]() 22 At the C1-C2 level, increased width of PVST could indicate atlanto-occipital subluxation. 21 In the setting of trauma, severe potentially incapacitating injuries to the cervical spine can present with PVST thickening as the only radiographic sign. Causes of increased PVST thickness include infection, neoplasm, hemorrhage, and fluid accumulation. Post-mortem before an autopsy in cases of suspected sudden infant death syndrome (SIDS) to exclude traumatic skeletal injury or skeletal abnormalities indicative of an underlying naturally occurring diseaseĬomputed bone maturity (bone age) assessmentĬomputed bone maturity (bone age) measurement are performed in cases of suspected growth delay or early pubertal development:Ĭomputed tomography scanogram for leg length discrepancy assessmentĬomputed tomography scanogram for leg length discrepancy assessment is performed in patients (children in most of the cases) with suspected inequality in leg length. The Normal Thickness of the PVST on MDCT. prone to instability by both degenerative and traumatic processes. Standard radiography of the cervical spine in rheumatoid arthritis (RA).(a) Lateral radiographs in neutral position and (b) during flexion in addition to (c) lateral and (d) anterior-posterior (AP) open-mouth view of the atlanto-axial region (45-year-old woman). Suspected non-accidental pediatric skeletal injury The atlantoaxial joint is an important 'transitional zone' in the cervical spine.
