Inflammatory pseudotumour is a benign mesenchymal lesion that has distinct pathological features. Patients often present with haematuria, abdominal pain or recurrent cystitis. There are overlapping features with bladder sarcoma in presentation, age range, and size, but the pseudotumour does not metastasise. Awareness of this unusual lesion is important to prevent its misinterpretation. Complete surgical excision of the tumour mass is the treatment of choice.
