Differential Diagnosis for Left Upper Quadrant Pain

The patient's symptoms suggest a possible gastrointestinal issue, with GERD being a potential cause. However, it's essential to consider other diagnoses to ensure accurate treatment.

  • Single Most Likely Diagnosis

    • Gastroesophageal Reflux Disease (GERD): The patient's symptoms are consistent with GERD, which is a common condition characterized by stomach acid flowing back into the esophagus, causing discomfort and pain in the upper abdomen, including the left upper quadrant.

  • Other Likely Diagnoses

    • Gastritis: Inflammation of the stomach lining can cause upper abdominal pain, including in the left upper quadrant, and can be related to or exacerbated by GERD.
    • Peptic Ulcer Disease: Ulcers in the stomach or duodenum can cause pain in the upper abdomen, which may be localized to the left upper quadrant.
    • Functional Dyspepsia: A condition characterized by recurring signs and symptoms of indigestion that have no obvious cause, which can include pain in the upper abdomen.

  • Do Not Miss Diagnoses

    • Pancreatitis: Although the spleen infarction has been ruled out, pancreatitis can cause severe upper abdominal pain that may radiate to the back and can be life-threatening if not promptly treated.
    • Splenic Flexure Syndrome: Also known as splenic flexure disorder, it involves the portion of the colon that is near the spleen and can cause left upper quadrant pain.
    • Diabetic Gastroparesis: Especially in diabetic patients, gastroparesis (delayed stomach emptying) can cause nausea, vomiting, and abdominal pain, including in the left upper quadrant.

  • Rare Diagnoses

    • Intestinal Obstruction: Although less common, an obstruction in the small or large intestine can cause severe abdominal pain, including in the left upper quadrant, and is a medical emergency.
    • Left Upper Quadrant Mass: Rarely, a mass in the left upper quadrant, such as a tumor or cyst, can cause localized pain.
    • Hiatal Hernia: A type of hernia where part of the stomach pushes up into the chest cavity, which can cause upper abdominal pain and symptoms similar to GERD.
