Resection of a ventrally located ossified thoracic spinal meningioma: illustrative case.

Background: Resection of calcified meningiomas in the ventral thoracic spinal canal remains a formidable surgical challenge despite advances in technology and refined microsurgical techniques. These tumors, which account for a small percentage of spinal meningiomas, are characterized by their hardness, complicating safe resection and often resulting in worse outcomes than their noncalcified counterparts.

Observations: The authors present the case of a 68-year-old woman with a ventrally located ossified meningioma at the T9-10 level, successfully treated via a posterolateral transpedicular approach.

Recurrence of arteriovenous malformation in an adult patient after complete resection: illustrative case.

Background: Complete resection of an arteriovenous malformation (AVM) is considered a curative treatment. In this paper the authors discuss two possibilities in the event of hemorrhage after satisfactory resection of an AVM: recurrence or remnant.

Observations: A 33-year-old female patient was diagnosed with an incidental right frontal AVM that was microsurgically resected and whose postoperative angiography showed no remnant.
