Osseous sarcoidosis, affecting bones and bone marrow, is uncommon but increasingly recognized. Advanced imaging like FDG-PET aids in detecting widespread skeletal involvement.
Area of Science:
- Rheumatology
- Oncology
- Radiology
Background:
- Sarcoidosis is a multisystem inflammatory disease of unknown etiology.
- Osseous and bone marrow involvement in sarcoidosis are rare, with limited case reports.
- This study focuses on the clinical, radiological, and pathological aspects of skeletal sarcoidosis.
Observation:
- Presents a case series of three patients with osseous sarcoidosis and one with bone marrow sarcoidosis.
- Utilizes fluorodeoxyglucose positron emission tomography (FDG-PET) for whole-body staging.
- Highlights findings from clinical evaluation, radiological imaging, and pathological examination.
Findings:
- Osseous sarcoidosis can manifest with diverse clinical and radiological features.
- FDG-PET is valuable for assessing the extent of skeletal sarcoidosis.
- Large bone and axial skeleton lesions are more frequently identified with modern imaging techniques.
Implications:
- Increased recognition of osseous sarcoidosis is necessary for timely diagnosis and management.
- Advanced imaging modalities improve the detection and characterization of skeletal sarcoidosis.
- Further research is warranted to understand the pathogenesis and optimize treatment strategies for osseous sarcoidosis.

Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...
