What causes cortical desmoid?
Cortical desmoid (also called tug lesion or periosteal desmoid) is an irregularity of the distal femoral cortex caused by repetitive stress at the attachment of the adductor magnus aponeurosis. It is most commonly seen in adolescents and is usually asymptomatic. It is a benign and self-limiting lesion.
Is a desmoid tumor cancerous?
Desmoid tumors are benign, which means they are not cancer. While the cells of the desmoid tumor do not travel to parts the body like cancer can, they can invade nearby tissue and are often very painful. Desmoid tumors can grow slowly or very quickly.
What is osteochondroma of the knee?
Osteochondroma is the most common type of benign bone tumor, true incidence of which is unknown as many are asymptomatic. It is usually found at the metaphysis of long bones commonly around the knee, proximal femur, and proximal humerus although they may develop in any bone that is formed by endochondral ossification.
Can a desmoid tumor be removed?
Surgery. If your desmoid tumor causes signs and symptoms, your doctor may recommend an operation to remove the entire tumor and a small margin of healthy tissue that surrounds it. But sometimes the tumor grows to involve nearby structures and can’t be completely removed.
What is cortical irregularity mean?
An abnormal irregularity of cortical bone. [ from HPO]
What is a Cortical desmoid lesion?
Cortical desmoid is a misnomer as this lesion does not histologically correlate to true desmoid tumors with more recent literature (c. 2020) 10 referring to these lesions as distal femoral cortical irregularities . These typically present in adolescents (10-15 years of age). There may be a male predilection.
What is a tug lesion in the knee?
Tug lesion, also known as avulsive cortical irregularity is an overuse injury that occurs in the knees of children. It can be mistaken for a tumor. Children between 11 and 14, depending on bone age, get this lesion. On xrays, at the distal posterior medial end of the femur, just above the growth plate, a cortical irregularity is seen.
What are cortical avulsive desmoids?
Cortical desmoids, also known as cortical avulsive injuries, Bufkin lesion or distal cortical femoral defects/irregularities, are a benign self-limiting entity that are common incidental findings. This is a classic ” do not touch ” lesion, and should not be confused with an aggressive cortical/periosteal process (e.g. osteosarcoma ).
What is a tug lesion on a MRI?
A tug lesion in musculoskeletal imaging is a term given to describe a bony traction reaction at a muscle attachment site likened to that of the “tug effect. They are benign and are placed as do not touch lesions.
