Vertebral fractures represent the most commonly encountered osseous lesions of the axial skeleton
in the peripartum period usually occurring during late pregnancy and early postpartum period while there are isolated reports of fractures related to the delivery process (Figs.
The pelvic girdle is well preserved, but its medial portion is covered by the axial skeleton
AS is an autoinflammatory SpA, which is characterized by progressive sacroiliitis to the axial skeleton
. Osteophyte formation and spine ankylosis are morbid manifestations, which reduce spine mobility and chest expansion.
The axial skeleton
consisted of the vertebrae and epineurals, and the median fin supports, including the proximal and distal pterygiophores.
Arthritis in sarcoidosis is usually peripheral, affecting bilateral small and large joints in a symmetrical fashion, whereas axial skeleton
involvement is rare (3, 4).
Positron emission tomography-computed tomography (a) shows diffuse marrow uptake throughout the axial skeleton
and (b) 3 months later shows significant improvement in the metabolic activity of the bone marrow.
It predominantly arises in the deep tissues of extremities, with only 5% arising from the axial skeleton
Bartonella osteomyelitis most commonly involves the axial skeleton
, with several cases reported in the vertebrae, skull, sternum, ribs, and pelvis [1, 11, 12].
Spondyloarthritis is a group of chronic inflammatory diseases primarily affecting the axial skeleton
with 0.5%-1.9% prevalence, making it one of the most common rheumatic diseases .
The axial skeleton
contains the bones of the skull (nasal, frontal, parietal, maxilla, and mandible), vertebral column (cervical, thoracic, lumbar, sacral, and caudal vertebrae), ribs, and sternum.
* Patchy sclerosis at most places in visualized axial skeleton
BMD was measured from the appendicular skeleton like femoral neck, and also in Ward's triangle, and for axial skeleton
from L1 - 5 lumbar spines.
Radiologic evaluation of axial skeleton
and also sternoclavicular region revealed no sclerosis and osteolysis and periosteal reaction formation.
Caption: FIGURE 2: CT of the abdomen showing numerous low attenuation lesions in the liver and spleen suspicious for metastatic disease along with soft tissue nodules in the anterior abdominal wall and numerous lytic lesions in the axial skeleton
These lesions are usually found to be localized in the diaphysis-metaphysis junction and sparing the epiphysis and the axial skeleton
