Differential Diagnosis for PSA of 5.6 in a 74-year-old

Single Most Likely Diagnosis

  • Benign Prostatic Hyperplasia (BPH): This is the most common cause of elevated PSA in older men. The age of the patient and the PSA level of 5.6, which is mildly elevated, make BPH a likely diagnosis. BPH is a non-cancerous enlargement of the prostate gland that can cause an increase in PSA levels.

Other Likely Diagnoses

  • Chronic Prostatitis: This condition, which involves inflammation of the prostate, can also cause an elevation in PSA levels. It's more common in younger men but can occur at any age.
  • Prostate Cancer: While not the most likely diagnosis given the mildly elevated PSA, prostate cancer is a significant concern in older men and must be considered, especially if other risk factors are present.

Do Not Miss Diagnoses

  • High-grade Prostate Cancer: Although less likely than BPH or chronic prostatitis, high-grade prostate cancer is a critical diagnosis that must not be missed due to its aggressive nature and potential for rapid progression. Even a mildly elevated PSA warrants further investigation in the context of other risk factors or symptoms.
  • Prostate Abscess: A rare but serious condition that can cause an elevated PSA. It requires prompt diagnosis and treatment to prevent serious complications.

Rare Diagnoses

  • Prostatic Infarction: This condition involves the death of prostate tissue due to a lack of blood supply. It can cause a sudden increase in PSA levels but is relatively rare.
  • Granulomatous Prostatitis: A form of prostatitis characterized by the presence of granulomas in the prostate. It can be caused by various conditions, including infections and autoimmune diseases, and can lead to an elevated PSA.
