abscess cavity
abscess chamber

In North America, after drainage, an abscess cavity is often packed.

A drain is left in the abscess cavity, and remains in place until the infection goes away.

Superimposed infection may convert these lesions into abscess cavities, and rarely, give rise to cancers.

The longest hospital stay was in a patient with an empyema associated with liver abscesses which required drainage until the abscess cavities resolved.

After the CT scan is done, a needle may be placed through the skin into the abscess cavity to confirm the diagnosis and treat the abscess.

After surgery, the mass was cut open and was full of "about 2 liters" of yellow pus and fluid with a large surgical pack (sponge) in the middle of an abscess cavity wall.

The cyst wall is formed by proliferating capillaries, inflammatory cells, and gliosis (proliferating glial cells) in the case of brain and proliferating fibroblasts in the case of abscess cavity.
