Shrunken right kidney with extensive amorphous calcification.
5 case questions available
Q: What is the most likely diagnosis? show answer
A: Tuberculous auto-nephrectomy - also known as 'putty kidney'.
Q: Is it safe to conclude that right kidney is non-functioning or non-excreting, based on the CT features? show answer
A: A nuclear DTPA scan is recommended to assess the functional status. However, in the case, contrast excretion in right ureter is seen during excretory as well as delayed scan, and thus excludes completely non-functional status, but no accurate estimate of residual renal function can be generated from this CT.
Q: A noticeable sharp kink is seen at pelviureteric junction in many such cases (not however in this case). What's the eponymous name given to such kink, and what does it mean? show answer
A: Kerr's kink is the term used to denote distortion of the pelviureteric junction due to adjacent parenchymal fibrosis secondary to prolonged inflammation.
Q: A non-opacified calyx or 'phantom calyx' is usually seen in renal tuberculosis due to infundibular strictures. It is also seen in which other renal condition? show answer
A: Transitional cell carcinoma may obstruct the infundibulum, also leading to a 'phantom calyx'.
Q: What other abnormalities of the urinary collecting system (ureter and bladder) are seen in chronic infection with TB? show answer
A: Saw-tooth (ragged edges) ureter, pipestem (rigid smooth) ureter, or corkscrew (tortuous) ureter, and thimble (small contracted) urinary bladder are common findings in urinary tract TB.
Case Discussion
This case demonstrates endstage renal tuberculosis (also known as TB autonephrectomy) resulting in the so-called putty kidney.
