Background: Lung abscess is an infectious disease of the lungs with pus filling the cavity in the lung parenchyma. In the pre-antibiotic era, one-third of patients who experienced lung abscesses died. The use of appropriate radiological equipment is expected to help narrow down the number of differential diagnoses so that an accurate diagnosis is obtained. We report a case of woman who had lung abcess with various imaging modality finding, Case Presentation: A 60 year old woman came to the ER with complaints of fever since 30 days before entering the hospital. Fever is accompanied by coughing and phlegm that is difficult to expel.Patient have a normal vital signs and several abnormalities in laboratory finding. Patients are examined using various radiology modalities. Conventional thoracic imaging examination suspected pleural effusion but after confirmation using a non-contrast Thorax CT Scan there was a hypodens area in the right inferior lobe and right medial lobe of the lung. In CT scan imaging using contrast obtained at the edge of the hypodencies area found enhanchment which leads to a picture of lung abscess Conclusion : The use of conventional chest radiographs has not provided maximum results in diagnosing lung abscess. Thorax CT scan is the best choice for diagnosing lung abscess because of its better sensitivity compared to conventional Thorax X-rays.
