The anterior interhemispheric approach is a workhorse for treatment of lesions in the third ventricle. In this case, we demonstrate the utility of this approach for resecting a complex third ventricular cavernous malformation. We discuss patient positioning, optimal location of the craniotomy, and surgical resection techniques for safe removal of these lesions. We also demonstrate the importance of gravity retraction using the falx to prevent injury to the dominant frontal lobe.The video can be found here: https://youtu.be/38woc28er7M.

Parietal Lobule

Background and Importance: Functional magnetic resonance imaging (fMRI) is a noninvasive and reliable tool for mapping eloquent cortex in patients prior to brain surgery. Ensuring intact perceptual and cognitive processing is a key goal for neurosurgeons, and recent research has indicated the value of including attentional network processing in pre-surgical fMRI in order to help preserve such abilities, including reading, after surgery. Clinical Presentation: We report a 42-year-old patient with a large cavernous malformation, near the left basal ganglia. The lesion measured 3.8 × 1.7 × 1.8 cm. In consultation with the patient and the multidisciplinary cerebrovascular team, the decision was made to offer the patient surgical resection. The surgical resection involved planned access via the left superior parietal lobule using stereotactic location. The patient declined an awake craniotomy; therefore, direct electrocortical stimulation (ECS) could not be used for intraoperative language localization in this case. Pre-surgical planning included fMRI localization of language, motor, sensory, and attentional processing. The key finding was that both reading and attention-processing tasks revealed consistent activation of the left superior parietal lobule, part of the attentional control network, and the site of the planned surgical access. Given this information, surgical access was adjusted to avoid interference with the attentional control network. The lesion was removed via the left inferior parietal lobule. The patient had no new neurologic deficits postoperatively but did develop mild neuropathic pain in the left hand. Conclusion: This case report supports recent research that indicates the value of including fMRI maps of attentional tasks along with traditional language-processing tasks in preoperative planning in patients undergoing neurosurgery procedures.

Abstract BACKGROUND AND IMPORTANCE: Cavernous malformations of the brainstem are a dilemma in terms of deciding when to operate, and they remain difficult to access surgically. We present a novel approach for the resection of a brainstem cavernous malformation CLINICAL PRESENTATION: A 59-year-old woman presented with a 1-month history of intermittent dysarthria, right facial weakness, and left arm and leg weakness. A magnetic resonance image revealed a 2-cm mass in the pons with blood products of differing ages, consistent with a cavernous malformation. We discussed with her the risks of surgical resection and conservative management. She decided to pursue conservative management. Two weeks later, she returned to the emergency room with diplopia and left-sided hemiplegia. Acute hemorrhage within the right pons was seen. She then chose to undergo surgical resection. CONCLUSION: The patient underwent an endoscopic transnasal approach for resection of a pontine cavernous malformation. Image guidance was used to identify key anatomic landmarks. A gross total resection was achieved without new neurological deficits. With physical and occupational therapy, the patient developed antigravity strength in her left upper and lower extremities before discharge. At her 4-week follow-up, she was ambulating independently with the assistance of a cane. We report the successful gross total resection of a pontine cavernous malformation via an endoscopic transnasal approach. This patient had improvement in neurological symptoms after surgical resection with minimal surgical morbidity. Technologic advances in endoscopic skull base approaches have provided access to lesions of the skull base previously requiring more invasive approaches.

Microsurgical Resection

In this surgical video, we present a 57-year-old man with neck pain, dizziness, and imbalance. MRI showed a heterogeneously enhancing mass lesion within the posterior medulla at the level of the foramen magnum. Because the patient was symptomatic from this cavernous malformation, the decision was made to proceed with surgical resection. The patient underwent a midline suboccipital craniotomy with C1 laminectomy for surgical resection of the cavernous malformation in the medulla oblongata, with concurrent monitoring of motor and somatosensory evoked potentials.The surgery and postoperative course were uneventful. The postoperative MRI showed gross-total resection of the mass with histopathology indicating a cavernous malformation. The patient continues to do well without recurrence at 7 years of follow-up. In this video, we demonstrate important microsurgical steps for the resection of this challenging and rare vascular malformation.The video can be found here: https://youtu.be/gbGleLowzxo.
