Appendiceal ganglioneuroma in neurofibromatosis type 2

Abstract

Here we report the case of a 30-year-old woman with a history of neurofibromatosis type 2 (NF2) who presented with an incidentally discovered pelvic mass on an ultrasound. The identity of the mass remained indeterminate following a CT and MRI, although appendiceal pathology was suspected. An elective laparoscopy and appendectomy were performed without complication and pathology on the specimen demonstrated an appendiceal ganglioneuroma. To our knowledge, there has been no prior documented case of an appendiceal ganglioneuroma in a patient with NF2. Furthermore, the current case is the first to report the MR characteristics of appendiceal ganglioneuromas.
