American Journal of Case Reports is ranked the World leading among journals dedicated to publishing clinical case reports. AJCR is indexed in Web of Science, PubMed/ PMC, Scopus

(1) CiteScore (Impact Factor - like by Scopus, Elsevier) is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.

(2) SNIP (Source Normalized Impact per Paper) measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields. SNIP takes into account the characteristics of the source's subject field, which is the set of documents citing that source.

(3) SJR is weighted by the prestige of a journal. Subject field, quality, and reputation of the journal have a direct effect on the value of a citation. SJR assigns relative scores to all of the sources in a citation network. Its methodology is inspired by the Google PageRank algorithm, in that not all citations are equal. A source transfers its own 'prestige', or status, to another source through the act of citing it. A citation from a source with a relatively high SJR is worth more than a citation from a source with a lower SJR. 

Clinical case reports are an invaluable first-hand source of evidence in medicine and a tool most often used in practice to exchange information and generate a more expanded search for evidence. In addition to the “evidence of what happened”, single or multiple cases are an important basis for further and more advanced research on diagnosis, treatment effectiveness, causes and outcomes of disease. However limited their conclusions may be, case reports remain a fundamental component of medicine, contributing greatly to the advancement of health care. In today's ever-expanding Evidence-Based Medicine, case reporting require a well-defined focus, content, and structure.

Presently, only a fraction of case reports is useful for clinical decision-making and bedside-decision oriented research. Therefore, the aim of the Journal is to gather case reports across medical disciplines, thereby integrating interdisciplinary, international medical knowledge.

BACKGROUND: Splenic artery aneurysm is uncommon in a healthy young male patient. With spontaneous rupture, it can quickly become life-threatening. Our aim is to highlight the possibility of splenic artery aneurysm among healthy young patients and its presentation as recurrent abdominal pain, while pending rupture is possible, which can present a diagnostic challenge. The rare occurrence and spontaneous rupture of a splenic artery aneurysm are often fatal outside an inpatient setting.
CASE REPORT: Here, we present the case of a 32-year-old patient who visited the Emergency Department with recurrent epigastric pain. While undergoing inpatient evaluation, had a spontaneous rupture of a splenic artery aneurysm with hypovolemic shock and a double-rupture phenomenon, necessitating emergency surgery.
CONCLUSIONS: With advances in modern imaging in recent years, the incidence of splenic aneurysm has increased 7-fold; therefore, being informed and considering it in the differential diagnosis might provide a window of opportunity and save lives.
