The authors present a case of a 65-year-old male who presented four times to the emergency department (ED) with left-sided chest pain. On the first three visits, the patient was admitted with a different diagnosis related to his chest pain. On the final visit, an abnormality on an imaging study performed in the ED led to the ultimate diagnostic test revealing the cause of the patient's symptoms. The patient's clinical presentation and ultimate clinical course are summarized, and a discussion of the differential diagnoses of his condition is presented.ACADEMIC EMERGENCY MEDICINE 2012; 19:e1-e6 ª 2012 by the Society for Academic Emergency Medicine
CASE PRESENTATIONA 65-year-old African American male presented to the emergency department (ED) with a chief complaint of chest pain. The patient complained of a 3-week history of constant sharp left-sided pain. During that time he was seen in our ED and admitted three times by different providers with the following diagnoses: cocaine chest pain, acute pancreatitis, and chest pain with electrocardiogram (ECG) changes. During each hospitalization, the patient was discharged within 24 hours with improvement and unremarkable evaluation. This is a short summary of the important findings found on chart review of his initial three visits. On Visit 1, the patient complained of chest pain and headache. Urine toxicology screening was positive for cocaine. ECG and chest radiograph were interpreted as normal. Serial troponin I and cardiac creatinine-kinase (CK) tests were obtained and were negative. On Visit 2, the patient complained of left-sided chest pain and left upper quadrant abdominal pain. The patient's serum lipase of 85 U ⁄ L (normal <63 U ⁄ L) and amylase of 157 U ⁄ L (normal <104 U ⁄ L) were slightly elevated in the setting of alcohol use. On Visit 3, the patient also complained of left upper quadrant abdominal pain in addition to the unchanged chest pain. Urinalysis was positive for microscopic hematuria. ECG showed an isolated T-wave inversion in V5 and T-wave flattening in the lateral leads. A noncontrast renal colic protocol computed tomography (CT) abdomen-pelvis scan was found to have no significant findings. Human immunodeficiency virus (HIV) testing was negative. Serial troponin I and cardiac CK tests were obtained and were negative.On Visit 4, the patient reported sharp left-sided chest pain that was constant in nature without change in quality over the last 3 weeks. He complained of severe nonradiating pain that was pleuritic in nature and dyspnea on exertion. He noted no improvement with acetaminophen, ibuprofen, oxycodone, or pantoprazole. His review of systems was negative with the exception of the symptoms noted above and an undetermined amount of unintentional weight loss. Past medical history included hypertension, gastroesophageal reflux disease, gastritis, treated scabies, Helicobacter pylori infections, and chronic back pain. The patient was not taking any medications regularly. His only allergy was penicillin, which caused adverse gastrointes...
