Management of sporadic schwannomas is often dictated by a patient's clinical presentation and the tumor's behavior. For patients who are managed nonsurgically, there are little data available about the expected natural history. ⋯ Distinct growth patterns were seen in extracranial sporadic schwannomas based on tumor location and patient demographics. Fast (>80% volume change per year) vs slow (5%-10% per year) tumor growth can often be ascertained within 2 follow-up images. Awareness of these patterns might have implications for patient counseling and therapeutic decision-making.

Thoracic epidurals remain the optimal method for providing postoperative analgesia after complex open abdominal and thoracic surgeries. However, they can be challenging to both place and maintain, as evidenced by a failure rate that exceeds 30%.1 Proper identification of the epidural space and accurate placement of the catheter are critical in order to deliver effective postoperative analgesia and avoid failure.2,3 This case series investigated the difficulty in correctly identifying the proper vertebral level for thoracic epidural catheter procedures when performed in the lateral decubitus position.

Middle cerebral artery aneurysms (MCAAs) have been considered good candidates for microsurgery. Our objective was to evaluate the risk of complications and the risk factors for complications with microsurgical treatment of MCAAs to better define the indications for microsurgery. ⋯ Microsurgical management of MCAAs can be performed with very low morbidity rates. In some cases, at least for factors that do not result in significant difficulty for endovascular therapy, such as the presence of an en passage artery or ruptured aneurysm, endovascular therapy can be considered to be as safe and effective as clipping.
