ACR-code 338-84 Four cases of patients in late middle age with back pain.
The first image shows increased density in the vertebra with loss of fine detail and a coarse zone of increased density making a thickened rim around the vertebra, a 'picture frame' vertebra. The CT cuts show irregular variation...

We report the case of an osseous hemangioma located in the seventh cervical vertebra with reactive osteoid formation and non-typical findings in the radiological and the histopathological examination, mimicking metastasis of a malignant tumor. To our knowledge, this is the first description of such a case in the literature.
Osseous hemangioma...

Radiology case 321-342 Young adult male with backache and enlarged palpable lymph glands in the neck and axillae.
There is a para-spinal shadow separate from the the silhouette of the overlying heart density and without loss of normal lower lobe vessel silhouettes. There is no rib crowding. The centre of radius...

Radiology case 338-1552 Clinical presentation: Lumbar spine of a child, no other detail.
The vertebrae have a thick band of abnormally increased bone density at their upper and lower margins. Within the body of each vertebra, there are curved areas of density change that roughly parallel the vertebral margins. The appearance can...

Radiology case 331-3327 Clinical presentation: Mature adult female, previous abdominal surgery, now presents with back pain.
The view shows an area of dense sclerosis in the body of the second lumbar vertebra without enlargement of the vertebral body. The anterior cortical margin cannot be seen against the desnity, but its anterior edge...

Eighty-two high performance young male fast bowlers (mean age 16.8 years) were tested immediately prior to the season for selected kinanthropometric and physiological data. Subjects were also filmed both laterally (200 Hz) and from above (100 Hz) while bowling so that their front foot impacted a force platform during the...

The word spondylolisthesis is derived from the Greek words spondylo, meaning spine, and listhesis, meaning to slip or slide. Spondylolisthesis is a descriptive term referring to slippage (usually forward) of a vertebra and the spine above it relative to the vertebra below.
Diagram shows how to grade spondylolisthesis. The 2 arrows,...

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...

Radiology case 332-3221 20 year old male with back pain.
The view is from an intravenous urogram, which shows normal pelvicalyceal systems and ureters. There is increased density on the right side of the 3rd lumbar vertebra. The density overlies the body, but also lies outside the vertebra. It is responsible...

Paget’s disease (PD) is a chronic metabolically active bone disease, characterized by a disturbance in bone modelling and remodelling due to an increase in osteoblastic and osteoclastic activity. The vertebra is the second most commonly affected site. This article reviews the various spinal pathomechanisms and osseous dynamics involved in producing...

Sarcoidosis is a systemic disease commonly affecting lung, skin, or eye. Sarcoidosis involved with osseous structures occurs in approximately 5% of patients, usually involving small bones. Spinal sarcoidosis is extremely rare. The authors report on a man in whom examination of a subclavicular lymph node biopsy specimen and its spinal...

The atlas is displaced forward upon the atlas, leaving a 2-3mm gap between the surface of the facet joints between atlas and axis vertebrae. The ramus of mandible, which is furthest away from the film is magnified and is projected over the atlas. Both this and the related facet joint...

Radiology case 331-3316 Clinical presentation: 42 year old man with known carcinoma of the bronchus and recent onset of acute back pain.
Pathologic fracture of body of lumbar vertebra. The pedicles are intact. The back of the vertebra is missing. The observation is that pedicle and body should both be on...

* congenital vertebral fusion
* location: lumbar or cervical
* height of the fused vertebral bodies equals the sum of heights of the involved bodies and intervertebral disc
* "waist" at level of disc space

"Calve-Kummel-Verneuil disease", "vertebral osteochondrosis" avascular necrosis of vertebral body age: 2-15 years
X-ray:
* uniform collapse of vertebral body into flat thin disc
* increased density of verbra
* neural arches not affected
* disc spaces are normal with normal intervertebral disc space
* intervertebral vacuum cleft sign (pathognomonic)
* no kyphosis
mnemonic: "FETISH"
* fracture
* eosinophilic granuloma
* tumor
* infection
* steroids
* hemangioma

Failure of spinal or neural tube fusion
The first feature to appear on the embryological plate is the neural groove that deepens with in-folding of its edges to form the neural tube. The openings of the tube close at 26-28 days after conception. Failure of closure at the top end causes...

Insufficiency fracture is a subgroup of stress fracture. Unlike the other subtype (ie, fatigue fracture), insufficiency fracture is caused by normal or physiologic stress upon weakened bone. Loss of bone trabeculae decreases the bone's elastic resistance.
Awareness is increasing concerning the occurrence of these fractures among older persons. Sites frequently affected...

Hemangiomas are tumors that occur in the bones of the spine, often found in the back above and just below the waist. They are benign, which means they do not tend to get worse or spread to other tissues. Hemangiomas usually only involve one vertebra

ACR-code 322-3310 Clinical presentation: A patient with previous mastectomy now with neck pain and lower limb weakness.
The plain image shows a complex appearance with a soft-tissue density behind the medial end of the right clavicle and a destructive process on the right side of the 2nd and 3rd thoracic vertebrae...
