摘要
Schwannomas are tumors of the macroglia cells, most frequently localized to the brain, in the pontocerebellar angle. We present the case of a 53 year-old female patient who presented multiple times with diffuse abdominal pain and was initially diagnosed as having a complex right adnexal mass. Exploratory laparotomy found a retroperitoneal mass and later on, the presence of a sacral schwannoma was found, suspected initially on contrast magnetic resonance imaging of the abdomen and pelvis, and confirmed by means of lesional biopsy and histopathology. This is a rare and unusual presentation accounting for only 5% of this tumor location and poses a challenge for imaging diagnosis, directly impacting the approach to the patient and any future interventions. There are few reports in the literature about giant sacral schwannomas, but these tumors have been found to extend within the spinal space towards the vertebral space, even occupying part of the abdomen. Hence, the importance of recognizing the presence of this tumor as well as its imaging features.
