Radiology · Urological imaging: schistosomiasis

Sample item

A man from an endemic region has terminal haematuria. A plain pelvic film shows a thin, curvilinear calcification outlining the bladder wall. What is the likely cause?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Urinary schistosomiasis (Schistosoma haematobium)

Eggs deposited in the bladder wall provoke granulomas and later calcification, which outlines the bladder as a fine line, and the condition predisposes to squamous cell carcinoma. Terminal haematuria is a classic symptom.

Option by option

  • A. Urinary schistosomiasis (Schistosoma haematobium) (correct)

    Correct. Linear bladder wall calcification with haematuria from an endemic area suggests schistosomiasis.

  • B. Bladder stone

    A stone is a dense intraluminal opacity.

  • C. Prostatic calcification

    Prostatic calcification lies below the bladder base.

  • D. Bladder tuberculosis

    Tuberculosis causes contraction and rarely a thin curvilinear calcification like this.
