Parvimonas micra is an obligate anaerobic bacterium and a known commensal of the human oral cavity and gastrointestinal tract. It is rarely associated with infections outside the oral cavity. Recently it has been isolated as a causative agent in a variety of systemic infections, but it has never been previously identified to cause a hepatic abscess. We report a 90-year-old woman with multiple hepatic abscesses caused by P. micra.

Renal infarction is caused by profound hypoperfusion secondary to embolic/thrombotic occlusion of the renal artery or vasospasm of the renal artery. We present a case of a 54-year-old patient who presented with nausea, vomiting, and vague abdominal pain. He had frequent episodes of migraine headaches and he treated himself with as needed rizatriptan. CT scan of the abdomen showed renal cortical infarction. After extensive investigations, etiology of his renal infarct was deemed to be due to rizatriptan.
