A liver abscess is a localized collection of pus in the liver, often caused by infection. It can result from bacteria, parasites, or fungi entering the liver, typically through the bloodstream or from nearby infections. Symptoms may include fever, abdominal pain, and jaundice. Diagnosis usually involves imaging tests like ultrasound or CT scans, and treatment often requires antibiotics or drainage of the abscess. In some cases, surgery may be necessary. Early detection and treatment are crucial to prevent complications related to the liver and overall health.
