Fat embolism most commonly occurs as a result of fractures of bones such as the femur or pelvis. [3] [1] Other potential causes include pancreatitis, orthopedic surgery, bone marrow transplant, and liposuction. [3] [2] The underlying mechanism involves widespread inflammation. [3] Diagnosis is based on symptoms. [2] Treatment is mostly ...
Fat necrosis in the breast occurs around 0.6%, this represents 2.75% of lesions that end up being benign. However, 0.8% of fat necrosis occurs from tumors of the breast, 1–9% occurs in breast reduction surgery. Individuals that are high risk include women around the age of 50yrs along with pendulous breasts. [8]
Caseous necrosis in T.B. is most common site of dystrophic calcification. Liquefactive necrosis in chronic abscesses may get calcified. Fat necrosis following acute pancreatitis or traumatic fat necrosis in breasts results in deposition of calcium soaps. Infarcts may undergo D.C. Thrombi, especially in veins, may produce phleboliths.
Mobile encapsulated fat necrosis (MEFN) is a rare medical condition featuring the formation of a fibrotic capsule around a small, necrotic mass of fatty tissue. It is asymptomatic and benign but may be mistaken for other neoplasms due to its typical presentation as a firm nodule beneath the skin that can be moved around within the tissue.
Indicated for people with exposed bone with symptoms of infection. This treatment modality may also be utilised for patients with other co-morbidities which precludes invasive surgical methods. This approach requires antimicrobial mouthwashes, systemic antibiotics and antifungal medication and analgesics. [52]
Treatment of necrosis typically involves two distinct processes: Usually, the underlying cause of the necrosis must be treated before the dead tissue itself can be dealt with. [ citation needed ] Debridement , referring to the removal of dead tissue by surgical or non-surgical means, is the standard therapy for necrosis.
Relief from chronic pain may be achieved through this procedure due to the reduced inflammation from the steroid medication, and steroid-induced fat necrosis which may reduce inflammation around the nerve, thereby reducing pressure on the pudendal nerve. This treatment may alleviate symptoms for up to 73% of people. [19]
In juxta-articular lesions without symptoms, there is dead bone and marrow separated from living bone by a line of dense collagen. Microscopic cysts form, fill with necrotic material and there is massive necrosis with replacement by cancellous bone with collapse of the lesions. [clarification needed]
