Case Reports
Symptomatic mass effect of a hypertrophied pericranial flap after repair of a dural defect: case report.
To detail a potential complication of the use of vascularized pericranial flaps in the repair of dural defects, namely, flap hypertrophy secondary to venous engorgement. ⋯ In this case, hypertrophy of the vascularized pericranial flap is hypothesized to have occurred because of venous congestion, possibly secondary to restriction of venous outflow by the overlying bone flap.

To assess the value of multiplanar reconstruction software in trajectory planning for depth electrode insertion in medically refractory epilepsy. ⋯ The use of reconstructed planes in preoperative trajectory planning allows for the insertion of additional electrode contacts within the target structure.

Accurate placement of ventricular catheters decreases the incidence of proximal catheter failure. The use of a frameless, interactive neuronavigational system can optimize catheter placement. ⋯ Frameless neuronavigation in the placement of ventricular catheters assures accurate catheter placement, thereby decreasing the incidence of proximal catheter failure. The absence of rigid head fixation allows additional cohorts to benefit from the apparatus. The use of the electromagnetic system provides a safe, simple, and easy adjunct to optimal catheter placement.

Vestibular schwannomas present significant management challenges in patients with neurofibromatosis Type 2 (NF2). We evaluated the results of gamma knife radiosurgery for the management of these tumors, focusing on tumor response, hearing preservation, and other factors affecting outcomes. ⋯ Stereotactic radiosurgery is a safe and effective management modality for neurofibromatosis Type 2 vestibular schwannomas. Although results do not seem to be as good as for patients with sporadic unilateral tumors, gamma knife radiosurgery results seem favorable and indicate that radiosurgery should be strongly considered for primary tumor management in selected patients.
