The authors describe two cases of utilization of intraoperative ultrasound as an auxiliary method for surgical resection of pancreatic insulinomas. We emphasize the importance of this procedure, particularly in patients whose tumors could not be well delimited using other preoperative methods, thus avoiding unnecessary ample resections and reducing postoperative complications.

Chordomas are rare neoplasms arising from notochordal remnants that persist along the axial skeleton. Intracranial chordomas occur more frequently in the midline. We describe an atypical case of an off-midline chordoma arising from the petrous apex, and discuss the embryogenic factors which determine that location, as well as the symptoms, imaging findings, surgical treatment and evolution.
Keywords: Chordoma. Petrous apex. Computed tomography. Magnetic resonance imaging.
