Leiomyoma in Retzius' space: An unusual location

Naoya Niwa et al. Can Urol Assoc J. 2013 Sep-Oct.

Abstract

We report the case of a 54-year-old woman who presented to our hospital with microscopic hematuria. An imaging study revealed a tumour in the Retzius' space. The tumour was surgically removed by an abdominal approach. Pathological examination revealed a leiomyoma. This case demonstrates a leiomyoma in an unusual location.

(B) Gadolinium-enhanced T1-weighted image revealing a tumor with signal intensity equal to that of muscle and surrounded by an enhanced uniform thick capsule. (C) The excised tumour encapsulated with thin fibrous tissue showed a solid and homogenous cut surface. (D) Hematoxylin and eosin-stained section (×400). The tumour consists of spindle-shaped uniform cells without nuclear atypia or necrosis.
