Perivesical abscess

A perivesical abscess is a localized collection of pus that occurs in the tissues surrounding the bladder.

This condition typically arises as a complication of an infection, such as a urinary tract infection, or following surgery or trauma to the pelvic region.

The abscess formation is a result of the body's immune response to contain the infection, creating a walled-off pocket of infection and inflammation.

Clinically, a perivesical abscess can manifest with symptoms such as lower abdominal pain, fever, chills, and urinary difficulties including painful urination or an increased urgency to urinate.

It may also lead to systemic signs of infection if the bacteria enter the bloodstream, potentially resulting in sepsis.

Diagnosing a perivesical abscess often involves imaging studies.

A CT scan of the pelvis is particularly useful as it can provide detailed images of the abscess and its relation to the bladder and other pelvic structures.

MRI may also be used in some cases to distinguish between abscess and other pelvic masses.

Treatment typically requires antibiotics to address the infection, and in many cases, surgical intervention to drain the abscess is necessary.

Early diagnosis and management are crucial to prevent complications such as rupture of the abscess, which could lead to peritonitis, a serious infection of the abdominal cavity.
