Core Tip	Parvimonas micra (P. micra) is an oral and gut commensal rarely causing liver abscess. We report a 52-year-old man who presented to the emergency department with intermittent fever, nausea, vomiting, and abdominal distention for 12 days. On presentation, liver ultrasound revealed a 7 cm hypoechoic lesion in the left lobe. Anaerobic blood cultures and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry performed on admission and 2 days later both identified P. micra, which provided a major diagnostic clue. Subsequent abdomen computed tomography, endoscopy, and endoscopic ultrasound confirmed a 23.5 mm strip-shaped lesion within the liver mass, with one end penetrating the liver. The patient underwent wedge resection of the abscess and repair of the gastric perforation, during which a 3.0 cm fish bone was removed. The clinical course of this patient highlights that pathogen identification is crucial for timely diagnosis and precise treatment.
