Incidence and Clinical Presentation of Pre- and Postoperative Seizures in Patients With Posterior Fossa Meningiomas.

Introduction: Seizures are a common symptom of supratentorial meningiomas with pre- and postoperative seizure rates of approximately 30% and 12%, respectively, especially in parasagittal and convexity meningiomas. Less is known about the association between seizures and posterior fossa meningiomas. This study evaluates the prevalence, potential causes, and outcomes of seizures in patients who have undergone surgery for posterior fossa meningioma.

The Brainstem Cavernoma Case Series: A Formula for Surgery and Surgical Technique.

: Cavernous malformations (CM) are vascular malformations with low blood flow. The removal of brainstem CMs (BS) is associated with high surgical morbidity, and there is no general consensus on when to treat deep-seated BS CMs. The aim of this study is to compare the surgical outcomes of a series of deep-seated BS CMs with the surgical outcomes of a series of superficially located BS CMs operated on at the Department of Neurosurgery, College of Tuebingen, Germany.

Paradigm Shift in the Treatment of Meningiomas.

Meningiomas are the most common brain tumor in adults with rising incidence rates due to an aging population globally, increased availability of neuroimaging, and increased awareness of this condition by treating clinicians and primary care physicians. Surgical resection remains the mainstay of treatment, with adjuvant radiotherapy reserved for higher grade meningiomas or tumors that undergo incomplete resections. Whereas these tumors were classically defined by their histopathological features and subtypes, recent work has uncovered the molecular alterations that may lead to tumor development and have important prognostic implications.

Treatment of recurrent and residual aneurysms with the low-profile Acandis Acclino stent: Multi-center review of 19 patients.

Objective: To evaluate the safety and efficacy of the low-profile Acandis Acclino microstent for embolization of recurrent and residual intracranial aneurysms.

Methods: Consecutive patients treated with the Acclino for aneurysm remnants at three German neurovascular centers were enrolled. The technical success, complications, angiographic and clinical outcome were investigated.

Impact of aneurysm morphology on aneurysmal subarachnoid hemorrhage severity, cerebral infarction and functional outcome.

Objective: Aneurysmal subarachnoid hemorrhage (aSAH) is associated with high morbidity. The objective was to evaluate, whether specific morphological aneurysm characteristics could serve as predictive values for aSAH severity, disease-related complications and clinical outcome.

Methods: A total of 453 aSAH patients (mean age: 54.
