Unusual Intraventricular Bullet Migration During Operation: A Case Report on Treatment Strategies.

Gunshot head injuries are increasingly prevalent in the urban setting and carry complex technical and clinical decision-making challenges to practicing neurosurgeons. Here, we present a unique case of a patient who suffered a gunshot injury and presented to the emergency department with an intraventricular bullet lodgment without significant neurological deficits. The patient was rushed to the operating room to remove the bullet after neuroimaging demonstrated its migration inside the ventricular system.

Petroclival meningiomas: Remaining controversies in light of minimally invasive approaches.

Surgical resection of petroclival meningiomas remains challenging due to their deep location and relationship to vital neurovascular structures. Although the natural history of these tumors involves a slow course, the incidence of cranial nerve deficits and the extent of tumor resection vary widely in the literature. Some reviews on this topic have been conducted, but data remain fragmentary and based on retrospective case series, which hinders attempts at meta-analysis.

Stereotactic radiosurgery for movement disorders.

Initially designed for the treatment of functional brain targets, stereotactic radiosurgery (SRS) has achieved an important role in the management of a wide range of neurosurgical pathologies. The interest in the application of the technique for the treatment of pain, and psychiatric and movement disorders has returned in the beginning of the 1990s, stimulated by the advances in neuroimaging, computerized dosimetry, treatment planning software systems, and the outstanding results of radiosurgery in other brain diseases. Since SRS is a neuroimaging-guided procedure, without the possibility of neurophysiological confirmation of the target, deep brain stimulation (DBS) and radiofrequency procedures are considered the best treatment options for movement-related disorders.
