Pyogenic Liver Abscess Growing Streptococcus constellatus in an Elderly Female With Recent Diverticulitis: A Case Report.

Pyogenic liver abscess (PLA) is known as a pus-filled lesion found in the liver which can quickly become fatal if not found and treated in a timely manner. The most common group of bacteria found in PLA is the Streptococcus Anginosus Group (SAG). Patients with PLA usually present with fever and right upper quadrant abdominal pain which can at times be referred to the right shoulder owing to dermatomal involvement. We present a case where a patient with a past medical history significant for recent diverticulosis presenting with a left lower quadrant abdominal pain, fever, and hypotension and on further workup was found to have a PLA. Blood cultures and cultures from the abscess grew Streptococcus constellatus. This bacteria is part of the SAG group however, it is rarely found in PLA and bloodstream.
