The imaging of osteomyelitis - PMC
In acute osteomyelitis, a collection of pus becomes surrounded by granulation tissue and reactive bone, forming an intraosseous abscess. Raised intramedullary pressure secondary to accumulation of pus leads to rupture of the cortex, creating a defect known as a cloaca, which drains pus from the bone to the surrounding tissues.

2023年4月1日 · Subacute osteomyelitis is characterized by the presence of Brodie's abscess, whilst chronic osteomyelitis usually involves the characteristic features of sequestrum, involucrum and cloaca. Treatment is multidisciplinary, involving Microbiology, Orthopaedics, Plastics and Vascular (when appropriate).
Osteomyelitis - Radsource
Chronic osteomyelitis. Inadequately treated acute osteomyelitis will progress to chronic osteomyelitis. Features of chronic osteomyelitis are a result of osteonecrosis, caused by disruption of the intraosseous and periosteal blood supply during the acute stage of disease.
struction seen in active osteomyelitis and involucrum, sequestrum, and cloaca in chronic osteomyelitis can be seen on plain radiographs but may take several weeks to appear with an up-to-two-week time lag. Serial plain radiographs are rec-ommended as they may have greater sensitivity and specificity with pro-gressive changes documented if iso-

The key feature of osteomyelitis is bone marrow edema, which is seen as a low signal on T1-weighted and high signal on T2-weighted and short tau inversion recovery (STIR) images. It is the first imaging sign and appears as early as in 24 to 48 hours.

Diabetic foot is a special condition with characteristic pathophysiologic and imaging features that suggest the likelihood of osteomyelitis and the main differential diagnostic consideration of acute on chronic neuropathic osteoarthropathy with or without osteomyelitis.
Osteomyelitis- What radiologists should know - ECR 2018 EPOS
As infections progress, the pus needs to exit the medullary cavity, and the cloaca is formed, which is a cortical defect that drains the pus to adjacent tissues. New bone is formed and deposited, covering the necrotic bone, as an involucrum .
