Recurrent Primary Suprahepatic Abscess Due to Providencia Stuartii: A Rare Phenomenon
Abstract
Gram-negative urease-producing bacilli, Providencia stuartii (P. stuartii), is reported in urinary tract infections, gastroenteritis, and bacteremia in humans but they rarely present with a hepatic abscess. We present a rare case of a recurrent suprahepatic cyst due to P. stuartii in a 45-year-old female, intravenous ( IV) heroin abuser with chronic hepatitis B and C. A 45-year-old female with 10 days status post right suprahepatic abscess drainage presented with recurrent, right, upper quadrant abdominal pain for one day. The pain was 7/10, sharp, radiated to the right back, and was associated with nausea, non-bloody non-bilious vomiting, and right-sided pleuritic chest pain. She was discharged after interventional radiology (IR) drainage of the abscess and completed 14 days of levofloxacin and metronidazole. On palpation, mild tender hepatomegaly was noticed. Complete blood count showed leukocytosis of 17.1 with left shift but liver enzymes within normal limits. Aspirated fluid cultures from the abscess showed P. stuartii. Blood and urine cultures were negative. A human immunodeficiency virus (HIV) test was negative. Hepatitis B virus (HBV) deoxyribonucleic (DNA) polymerase chain reaction (PCR) showed > 17 million IU/ml and hepatitis C virus (HCV) Ab reactive. A right, upper quadrant sonogram showed 4.1x0.9x2.7 cm fluid collection anterior to the right liver lobe. A computed tomography (CT) abdomen showed a dominant 5.2x5.5x3.9 cm hypodense lesion consistent with an…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
