Differential Diagnosis for Acute Epigastric Pain in Patients with Multiple Myeloma

Single Most Likely Diagnosis

  • Hypercalcemia-induced pancreatitis: This condition is a common complication in patients with multiple myeloma due to elevated calcium levels, which can cause pancreatic inflammation, leading to acute epigastric pain.

Other Likely Diagnoses

  • Gastroesophageal reflux disease (GERD): Patients with multiple myeloma may experience GERD due to various factors, including medication side effects, leading to epigastric pain.
  • Peptic ulcer disease: The use of nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids in multiple myeloma treatment can increase the risk of peptic ulcers, causing acute epigastric pain.
  • Amyloidosis: Amyloid deposits can accumulate in the gastrointestinal tract, including the stomach, leading to epigastric pain in patients with multiple myeloma.

Do Not Miss Diagnoses

  • Myocardial infarction: Although less common, myocardial infarction can present with epigastric pain, especially in patients with atypical symptoms, and is crucial to diagnose promptly due to its high mortality rate.
  • Aortic dissection: This is a life-threatening condition that can cause severe epigastric pain and must be ruled out, especially in patients with hypertension or other risk factors.

Rare Diagnoses

  • Intra-abdominal plasma cell tumors: Rarely, multiple myeloma can manifest as intra-abdominal plasma cell tumors, which can cause epigastric pain due to local compression or infiltration of surrounding tissues.
  • Splenomegaly or splenic infarction: Although less common, splenomegaly or splenic infarction can occur in patients with multiple myeloma, leading to referred epigastric pain.
