What is pitting in MRI?
Abstract. Herniation pits are small benign lucent oval lesions within the anterior aspect of the superolateral femoral neck and were first described in 1982 by Michael J. Pitt.
What is a small synovial herniation pit?
Herniation pits are small benign oval lesions that were reported to be always lying within the super-lateral femoral neck, and were first described in 1982 by Michael J. Pitt. They are usually a unilateral incidental finding along with asymptomatic course.
What is a synovial herniation cyst?
Synovial cysts are common in joints such as the knee, ankle, hand, and wrist, but uncommon in the hip joint. Histologically, a synovial cyst is an extension of the joint capsule with a lining of synovial cells, and it often communicates with the adjacent joint.
Where is the femoral head located?
Anatomical terms of bone The femoral head (femur head or head of the femur) is the highest part of the thigh bone (femur). It is supported by the femoral neck.
What is the femoral neck?
The femoral neck is the most common location for a hip fracture. Your hip is a ball and socket joint where your upper leg meets your pelvis. At the top of your femur (which is your thigh bone) is the femoral head. This is the “ball” that sits in the socket. Just below the femoral head is the femoral neck.
Can a synovial cyst be cancerous?
Synovial cysts are abnormal fluid-filled sacs in joints in the spine. These cysts are benign, which means they are not cancerous. Synovial cysts typically develop as a result of degenerative changes that occur with aging.
What is femoral head necrosis?
Avascular necrosis (AVN) of the femoral head is a pathologic process that results from interruption of blood supply to the bone. AVN of the hip is poorly understood, but this process is the final common pathway of traumatic or nontraumatic factors that compromise the already precarious circulation of the femoral head.
When does the femoral head appear?
In healthy children the epiphysis appeared between the first and seventh month. In more than 95% of the children, the epiphysis was sonographically present after the seventh month. In children with congenital hip dysplasia the first appearance of the femoral hip epiphysis had a retardation of one to two months.
What does symptomatic synovial herniation pit on MRI indicate?
Symptomatic synovial herniation pit—MRI appearances pre and post treatment. They have a thin sclerotic rim and represent benign bone pits that are felt to be a result of mechanical forces causing herniation of soft tissue and synovium through a defect in the bone. They are usually a unilateral incidental finding and rarely present with hip pain.
What is the prognosis of synovial pit in hip?
Synovial pits may have atypical clinical and radiological course, and this can raise concerns especially with symptomatic hip that may encourage surgical interventions. However, due to benign course of these lesions, we do not recommend any surgical intervention for such lesions.
What is a herniation pit?
Herniation pits are small benign lucent oval lesions within the anterior aspect of the superolateral femoral neck and were first described in 1982 by Michael J. Pitt. They are widely believed to occur as a result of mechanical forces from the overlying capsule resulting in herniation of soft tissues and synovium through a small bony defect.
