Case ReportHistory
Exam
Prior Study
Findings
Overall
Overall there is a bony demineralization noted with coarsening of the trabecular pattern within the long bones. There is blurring of the cortices of the long bones compatible with areas of bony reabsorption. These are particularly noted involving the radius and ulna on either side.
Skull
There is a right-sided ventriculoperitoneal shunt catheter present. There is no fracture. The anterior fontanelle is widened. There is loss of differentiation between the inner and outer table of the skull with a salt-and-pepper like pattern of the bone. There is crowding of the bony base of the skull. Additionally, there is an appearance of "floating teeth" a finding which can be seen in the setting of renal osteodystrophy.
Spine
There is no evidence for fracture or subluxation. There is a bulbous appearance of the visualized thoracolumbar vertebrae. There is a somewhat S shaped curvature of the thoracolumbar spine on the frontal view. There is early appearance of "rugger jersey spine" demonstrated by alternating dense and lucent dense appearance of the lumbar vertebrae with an almost "bone in bone" like appearance.
Ribs
There is an appearance of fraying and widening of the anterior rib ends, best appreciated on the oblique chest images. There is no evidence for acute or chronic fracture. 12 bilateral ribs are present. There is bony reabsorption of the distal right clavicle.
Upper Extremities
There is a healing fracture involving the right humeral metaphysis with adjacent periosteal reaction along the lateral margin. The remaining osseous structures of the upper extremities are unremarkable without evidence of fracture or dislocation. Alignment is maintained.
Lower Extremities
There is fraying and irregularity along the medial aspect of the right femoral head. There are metaphyseal corner fractures involving the distal femoral metaphyses with additional component of fraying and cupping of the metaphyses. This appearance is noted bilaterally. There is superior lateral dislocation of the left hip as seen on the frontal babygram view. Furthermore, there is anterior bowing of the bilateral femurs. There is bony reabsorption, widening and irregularity at the bilateral sacroiliac joints, the right appearing worse than the left.
Hands
Overall, there is a coarse widened trabecular pattern with scattered areas of lucencies noted within the metacarpals and phalanges. This is worse on the right than the left. For example there is a lucency within the thumb metacarpal on the right as well as the left fifth proximal phalanx. There is bony reabsorption involving the distal tuft of the fourth right distal phalanx. There is a suggestion of bony reabsorption of the distal phalanges of the left third and fifth digits. There is fraying and cupping of the distal ends of the ulnar and radial metaphyses.
Ankles
There are metaphyseal corner fractures involving the distal tibial and fibular metaphyses with additional component of fraying and cupping of the metaphyses. The talocalcaneal angle is above normal limits. There is a suggestion of hindfoot valgus. However, weightbearing films are not obtained.
Other Findings
There are coarse interstitial lung markings with retrocardiac atelectasis. The cardiomediastinal silhouette is enlarged in size. There are gaseous nonobstructed loops of bowel present within the abdomen. There is no pneumatosis or portal venous gas.
Impression
2. Overall, there is a coarsened trabecular pattern with areas of bony reabsorption as detailed above.
3. Bony reabsorption noted at the level of the bilateral sacroiliac joints, the right appearing worse.
