What is periosteal thickening?
A periosteal reaction is the formation of new bone in response to injury or other stimuli of the periosteum surrounding the bone. It is most often identified on X-ray films of the bones.
What causes hypertrophic osteoarthropathy?
Hypertrophic osteoarthropathy (HOA) is mainly caused by mainly fibrovascular proliferation. It is characterized by a combination of clinical findings, including severe disabling arthralgia and arthritis, digital clubbing, and periostosis of tubular bones with or without synovial effusion.
How to look for hypertrophic osteoarthropathy?
Primary hypertrophic osteoarthropathy Periosteal proliferation is usually shaggy and is associated with irregular excrescences and diaphyseal expansion. Periosteal proliferation begins in the epiphyseal region at the tendon-muscle attachment. Rarely, thickening of the calvarium and skull base is seen.
What is hypertrophic arthropathy?
Hypertrophic osteoarthropathy (HOA) is a medical condition characterized by abnormal proliferation of skin and periosteal tissues involving the extremities and characterized by three clinical features: digital clubbing (also termed Hippocratic fingers), periostosis of tubular bones, and synovial effusions.
What does the word periosteal mean in medical terms?
Medical Definition of periosteal 1 : situated around or produced external to bone.
Which type of periosteal reaction shows aggressiveness of tumor?
The spiculated pattern is an aggressive form of periosteal reaction that includes both hair- on-end and sunburst subtypes. Spicules of bone form perpendicular to the periosteal surface in the hair-on-end subtype (Figs. 4 and 5), which is highly suggestive of Ewing’s sarcoma.
Is hypertrophic osteoarthropathy Painful?
Patients with hypertrophic osteoarthropathy due to neoplastic or inflammatory pulmonary conditions typically report pain and swelling in joints and long bones. Joint symptoms can range from mild to severe arthralgias, and it can involve the small and large joints [1].
What does Osteoarthropathy mean?

What causes segmental or diffuse wall thickening of the colon?
With the exception of lymphoma, segmental or diffuse wall thickening is usually caused by benign conditions, such as ischaemic, infectious and inflammatory diseases. Key points: • Thickening of the bowel wall may be focal (<5 cm) and segmental or diffuse (6-40 cm or >40 cm) in extension.
What causes focal bowel wall thickening?
Conclusion: Focal bowel wall thickening may be caused by tumours or inflammatory conditions. Bowel tumours may appear as either regular and symmetric or irregular or asymmetric thickening. When fat stranding is disproportionately more severe than the degree of wall thickening, inflammatory conditions are more likely.
Does ulcerative colitis cause stratified bowel wall thickening?
Bowel wall thickening with a stratified pattern may be also seen in both ulcerative colitis (UC) and Crohn’s disease, indicating acute, active disease [2, 7, 26]. Crohn’s disease may occur in any part of the gastrointestinal tract but predominantly affects the small bowel, particularly the ileum and right colon [2, 7].
What causes thickening of the colon on CT scan?
Patients with Crohn’s disease or inflammatory bowel diseases often develop scar tissue inside the intestines, which cause the walls to thicken. The National Center for Biotechnology Information states that thickening of the colon is often observed during a CT scan for some other purpose.
