Hemorrhagic Cholecystitis in a Patient Under Anticoagulant and Antiplatelet Therapy: A Case Report.

ABSTRACT

Hemorrhagic cholecystitis is an uncommon presentation of acute cholecystitis. Due to its etiology and unspecific clinical data, it is an entity that represents a diagnostic challenge. We present a case of a 70-year-old male with diabetes type 2, hypertension, and chronic kidney disease with hemodialysis, who attended the emergency department with sudden-onset abdominal pain in the epigastrium. The patient presented no additional symptoms, a normal electrocardiogram, but due to the characteristics of the pain and elevated troponin I, emergency medicine specialists considered an acute coronary syndrome and initiated antiplatelet and anticoagulant therapy. Due to persistent abdominal pain, a decrease in hemoglobin, and the onset of arterial hypotension, a computed tomography (CT) scan was performed, which revealed perforation of the gallbladder, apparent hemorrhagic cholecystitis, and hemoperitoneum. The patient underwent emergent surgery, where CT findings were confirmed. In our case, the suspicion of hemorrhagic cholecystitis arose until the clinical case was advanced, after receiving anticoagulant and antiplatelet therapy, and it was confirmed during surgery and with histopathology. This concludes that hemorrhagic cholecystitis is a rare disease and difficult to diagnose. Therefore, studies should focus on clinical presentation and risk factors (e.g., trauma, malignancy, renal failure, cirrhosis, and anticoagulation therapy) to promote early diagnosis and avoid complications.
