Differential Diagnosis for a 68-year-old Female with Hematuria

Single Most Likely Diagnosis

  • Degenerative Fibroid: The presence of an incidental calcification outside of the urinary system, likely a degenerative fibroid, as noted in the CT Pelvis impression, could be causing the hematuria, especially if the fibroid is large enough to compress or irritate the bladder or urethra.

Other Likely Diagnoses

  • Urinary Tract Infection (UTI) with Negative Culture: Although the culture is negative, it's possible that the infection was caused by an organism that doesn't grow well in standard cultures, or the patient might have been on antibiotics recently, which could lead to a false-negative result.
  • Kidney Stones: Despite the CT not showing abnormalities of the kidneys or upper tracts, small stones might not be visible, and the patient could still be experiencing hematuria due to a stone that is not yet causing an obstruction.
  • Bladder or Urethral Trauma: Given the patient's age, any recent activities or procedures that could have caused trauma to the bladder or urethra should be considered, even if the CT does not show abnormalities.

Do Not Miss Diagnoses

  • Bladder Cancer: Hematuria is a common presenting symptom of bladder cancer. Although less likely, missing this diagnosis could be fatal, so it must be considered and ruled out with further testing, such as cystoscopy.
  • Upper Genital Tract Cancer: Cancers of the uterus, cervix, or ovaries could potentially cause hematuria, either by direct invasion into the urinary tract or by metastasis. These conditions are critical to identify early.
  • Renal Artery Aneurysm or Arteriovenous Malformation (AVM): These vascular abnormalities could cause hematuria and are potentially life-threatening if they rupture.

Rare Diagnoses

  • Endometriosis Involving the Urinary Tract: Although rare, endometriosis can involve the bladder or ureters, leading to cyclic hematuria.
  • Schistosomiasis: In patients who have traveled to or lived in areas where schistosomiasis is endemic, this parasitic infection could cause hematuria due to bladder involvement.
  • Tuberculosis of the Urinary Tract: Another rare cause of hematuria, especially in patients with a history of exposure to TB or from endemic areas.
