Sacral ganglioneuroma in a 19-year-old woman.

Ganglioneuroma is a rare benign neural crest tumour, located usually in the posterior mediastinum and retroperitoneum. It tends to acquire significant size before symptoms or clinical signs become apparent. We report a 19-year-old female who underwent excision of a pelvisacral ganglioneuroma via a Pfannenstiel incision, after an abdominopelvic CT scan for investigation of left iliac fossa pain and menorrhagia detected a pelvic mass. This report highlights the importance of complete surgical excision of these lesions and the collaboration of multiple surgical units in managing these often large, variably located tumours.
