Pseudopneumoperitoneum Caused by Klebsiella pneumoniae Pyogenic Liver Abscess

A 39-year-old male patient without any medical history presented to the Emergency Department with a 1-week history of intermittent fever and chills. He denied having cough, sore throat, abdominal pain, nausea, vomiting, dysuria, or diarrhea. Physical examination revealed tachycardia (heart rate 110 beats/min) without fever (body temperature, 37 °C) or hypotension (blood pressure, 113/67 mm Hg). Abdomen was soft-palpated without tenderness. Standing chest x-ray study (CXR) showed a heterogeneous radiodensity with air-fluid level lesion over the right upper abdomen (Figure 1, black arrow).
