Differential Diagnosis for Back Pain plus Blood in Semen

Single Most Likely Diagnosis

  • Prostatitis: This condition is characterized by inflammation of the prostate gland, which can cause back pain and hematospermia (blood in semen). The proximity of the prostate gland to the seminal vesicles and the potential for inflammation to affect these structures make prostatitis a plausible explanation for both symptoms.

Other Likely Diagnoses

  • Benign Prostatic Hyperplasia (BPH): Enlargement of the prostate gland can lead to back pain due to the pressure exerted on surrounding structures and hematospermia due to the disruption of the normal prostate and seminal vesicle anatomy.
  • Prostate Cancer: Although less common than BPH or prostatitis, prostate cancer can also cause back pain, especially if it has metastasized to the bones, and hematospermia due to local invasion of the seminal vesicles or prostate gland.
  • Seminal Vesiculitis: Inflammation of the seminal vesicles can cause both back pain and hematospermia, as these structures are closely related to the prostate gland and can be affected by similar pathological processes.

Do Not Miss Diagnoses

  • Testicular Cancer: Although testicular cancer primarily presents with a testicular mass, advanced disease can cause back pain due to retroperitoneal lymph node involvement and potentially hematospermia if there is metastasis to the prostate or seminal vesicles.
  • Spinal Metastases: Metastatic disease to the spine from any primary cancer can cause severe back pain and, if the metastasis involves the spine near the prostate or seminal vesicles, could potentially cause hematospermia through local effects.

Rare Diagnoses

  • Schistosomiasis: A parasitic infection that can involve the urinary and reproductive systems, leading to hematospermia and potentially back pain if there is significant involvement of the urinary tract or prostate.
  • Tuberculosis of the Genitourinary Tract: Although rare in many parts of the world, genitourinary tuberculosis can cause a wide range of symptoms including back pain and hematospermia due to its potential to affect any part of the genitourinary system.
