Pseudotumoral cystitis: a case of acute urinary retention in a newborn

Pseudotumoral cystitis is a subtype of eosinophilic cystitis – a rare inflammatory bladder condition with a wide range of clinical presentations. In this article, we describe the case of a male infant with an antenatally diagnosed unilateral hydronephrosis, presenting at 24 hours of age with urinary retention. An initial urinary tract ultrasound scan showed a hyperechoic bulge at the bladder base with persistent hydronephrosis. As far as we can tell, this is the second case of neonatal pseudotumoral cystitis and the ninth case of paediatric pseudotumoral cystitis to be reported in the literature.

Key points
  1. All parents should be advised to seek urgent medical attention if their baby has not passed urine within 24 hours of birth, especially those who are more at risk due to antenatal renal abnormalities.
  2. Acute urinary retention in a newborn is a surgical emergency and needs to be managed urgently.
  3. Posterior urethral valves are the most common cause of urinary outflow obstruction in male infants; however, when it is not clear it is important to consider the possibility of an obstructing mass or retention secondary to neurological causes.
