Diffusely sclerotic bones (osteosclerosis) incidentally seen on PA chest radiograph performed for suspected lower respiratory tract infection. Also, multilevel H-shaped vertebrae are seen.
Case Discussion
Osteosclerosis or diffuse increased bones density is caused by many underlying diseases including:
- congenital, e.g. osteopetrosis (usually associated with extensive nephrocalcinosis)
- hematological, e.g. myelofibrosis, mastocytosis (dermatographia is very characteristic for this entity) and sickle cell anemia
- metabolic, e.g. secondary hyperparathyroidism (renal osteodystrophy)
- malignant, e.g. metastatic disease, most commonly from prostate or breast primary neoplasm
- toxic, e.g. fluorosis, vitamin D hypervitaminemia
In this case, sickle cell anemia turned out to be a cause (H-shaped vertebrae helped to narrow the differential).
