Randomized Controlled Trial Comparative Study
Chronic subdural hematoma: comparison of two surgical techniques. Preliminary results of a prospective randomized study.
The optimal treatment for chronic subdural hematoma (CSDH) is not yet well defined and research for efficient surgical solutions continues. Burr hole craniotomy (BHC) is a common treatment and twist drill craniostomy (TDC) is a less invasive alternative. A closed-system drainage with subdural expansion catheter and suction reservoir can be used to enhance the TDC procedure. ⋯ Preliminary results indicate TDC and BHC as at least equally effective, however TDC favors faster regression of residual subdural effusion, is a faster procedure, and seems to be associated with fewer recurrences. If confirmed at the end of the study, these results could indicate TDC with suction as the elective surgical treatment for CSDH.

Case Reports Comparative Study
Supratentorial cavernomas in eloquent brain areas: application of neuronavigation and functional MRI in operative planning.
Cavernomas located in eloquent areas of cerebral hemispheres represent a challenge for the neurosurgeon. An accurate surgical approach is essential to completely remove the lesion with function preservation. Aim of this study was to evaluate the usefulness of integration between standard magnetic resonance imaging (MRI) for neuronavigation and functional MRI (fMRI) in preoperative planning and intraoperative removal of cavernomas. ⋯ In all the cases the use of neuronavigation allowed minimally invasive approaches and radical excision of the lesions. Moreover, fMRI seemed to provide important additional information in patients with lesions in eloquent brain areas, allowing a more aggressive approach on the perilesional tissue to the aim of resolving seizures, in absence of an increase in the morbidity rate.

The aneurysms of the paraclinoid region are a heterogeneous group of lesions, whose terminology and classification are contradictory because of the complex anatomy and the lack of key anatomical references. A surgical anatomical study to identify an anatomical reference is presented, a new classification of these aneurysms is proposed, and radiological guidelines are given to distinguish an intra from extradural lesion on the x-rays. ⋯ A new classification of the aneurysms of the paraclinoid region which uses the DDR as key anatomical element is proposed. Radiological guidelines able to identify the DDR and, thus, to distinguish intra versus extradural aneurysms are provided.

Treatment of ophthalmic segment aneurysms is technically demanding and still associated with a relatively high morbidity and mortality. The refinements of surgical techniques combined with the development of indirect methods of treatment have greatly improved the outcome in treating these lesions. We present our clinical experience and discuss treatment strategies. ⋯ Direct obliteration of the aneurysm utilizing advanced surgical techniques is our preferred treatment approach, whenever possible. In case of unclippable large or giant aneurysms, the surgical or endovascular occlusion of the proximal internal carotid artery with or without an extracranial-intracranial by-pass is an option. A highly skilled team including a cerebrovascular and an endovascular surgeon is essential to achieve good outcomes in treating these lesions.

Review Case Reports
Lymphoplasmacyte rich meningioma. A case report and review of the literature.
A peculiar type of meningioma with conspicious plasma-cell components is described. In accordance with the World Health Organization's Histological Typing of Tumours of the Central Nervous System, this rare clinical entity is recently designed as lymphoplasmacyte rich (LPR) meningioma. ⋯ Actually, the origin (neoplastic or inflammatory) of this tumor is unclear; its biological behavior and clinical course are anomalous so it is considered closer to intracranial inflammatory masses rather than typical meningioma. In this paper, a new case of intracranial LPR meningioma occurring in a woman, is reported and a review the literature is made.
