title: Clinical Case of the Month: A 48-Year-Old Man With Fever and Abdominal Pain of One Day Duration.
abstract: A 48-year-old man residing in a mental health department inpatient program with a history of schizoaffective disorder presented to the emergency department with a chief complaint of fever and intense abdominal pain for one day. The patient stated he initially fell in the shower and afterwards experienced back pain. He was transferred to an acute care unit within the facility for further evaluation. The facility physician noted that the patient had a mild temperature elevation and abdominal rigidity on exam. At that time, he was given two doses of benztropine intramuscularly, and transferred to our hospital for further evaluation. The patient exhibited fever, diffuse abdominal pain and a nonproductive cough, but denied chills, dysuria, urinary frequency, hematuria, weakness, diarrhea, melena or hematochezia. He did have a one-week history of constipation for which he was given sodium phosphate enemas, magnesium citrate and docusate sodium, eventually resulting in a bowel movement. He also complained of new onset dysphagia. There were no recent changes to his medications, which included clonazepam, divalproex sodium extended release, olanzapine and risperidone. He denied use of tobacco, alcohol or illicit drugs.
