Pseudotumoral cystitis in children: a review of the ultrasound features in four cases.

Pseudotumoral cystitis is an uncommon inflammatory condition which may masquerade as a bladder tumour in children. There are a variety of clinical presentations such as haematuria, dysuria, infection and obstruction. Reported causative factors include infection (bacterial, fungal and parasitic) and allergy. Ultrasound is an excellent imaging modality for demonstrating this intravesical lesion although the spectrum of features is poorly described in the literature. We report our recent experience of four patients with pseudotumoral cystitis and describe the clinical features and ultrasound appearance of this condition in children.
