Radiology case 462-23 Clinical presentation: Swelling and discomfort in the left ankle in an adult male from India.

Radiology case 311-231 Clinical presentation: 30 year old Indian man with neck pain and stiffness.
There is a soft tissue swelling, which displaces the retropharyngeal air-tissue boundary forwards. The centre of radius of the bulge lies roughly at the level of the axis vertebra, where an anterior defect in the vertebra, below...

Twenty-one patients with surgically and/or pathologically proved tuberculosis of the tendon sheaths or bursae were evaluated. Routine radiography, arthrography, computed tomography (CT), and magnetic resonance (MR) imaging were used in some or all of the patients.
CONCLUSION: All imaging methods can provide complementary information that is helpful for determination of therapy....

FLEXION:
* bilateral interfacetal dislocation
* flexion teardrop fracture (usually C5 or C6)
EXTENSION:
* extension teardrop fracture (usually C2 or C3)
* hangman's fracture
* extension-dislocation
* extension-fracture-dislocation
* odontoid fracture
VERTICAL COMPRESSION:
* Jefferson burst fracture

Loss of disk space with destruction of adjacent vertebral endplates, with or without vertebral sclerosis or adjacent soft tissue masses is characteristic of vertebral osteomyelitis, especially in the appropriate clinical setting with appropriate risk factors.

X-linked dominant defect in renal tubular resorption of phosphate
* presents in 1st yr
* progressive limb deformities
xray:
* less severe changes than other rickets
* presents later
DDx features:
* family hx
* normal serum calcium
* marked hypophosphatemia (decreased PO4)
* no secondary hyperPTH
