Inflammatory myofibroblastic tumour (IMT) of the bladder is a rare tumour of indeterminate malignant potential with myofibroblastic differentiation, with a generally benign but rarely aggressive behaviour. Vesical IMT is usually treated by transurethral resection or partial cystectomy. Herein we describe a case of a woman who underwent laparoscopic excision of an IMT of the bladder, initially diagnosed as deep infiltrating endometriosis.
