No robust evidence is provided by literature regarding the management of intracranial hypertension following severe traumatic brain injury (TBI). This is mostly due to the lack of prospective randomized controlled trials (RCTs), the presence of studies containing extreme heterogeneously collected populations and controversial considerations about chosen outcome. A scientific society should provide guidelines for care management and scientific support for those areas for which evidence-based medicine has not been identified. However, RCTs in severe TBI have failed to establish intervention effectiveness, arising the need to make greater use of tools such as Consensus Conferences between experts, which have the advantage of providing recommendations based on experience, on the analysis of updated literature data and on the direct comparison of different logistic realities. The Italian scientific societies should provide guidelines following the national laws ruling the best medical practice. However, many limitations do not allow the collection of data supporting high levels of evidence for intracranial pressure (ICP) monitoring and decompressive craniectomy (DC) in patients with severe TBI. This intersociety document proposes best practice guidelines for this subsetting of patients to be adopted on a national Italian level, along with joint statements from "TBI Section" of the Italian Society of Neurosurgery (SINch) endorsed by the Neuroanesthesia and Neurocritical Care Study Group of the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI). Presented here is a recap of recommendations on management of ICP and DC supported a high level of available evidence and rate of agreement expressed by the assemblies during the more recent consensus conferences, where members of both groups have had a role of active participants and supporters. The listed recommendations have been sent to a panel of experts consisting of the 107 members of the "TBI Section" of the SINch and the 111 members of the Neuroanesthesia and Neurocritical Care Study Group of the SIAARTI. The aim of the survey was to test a preliminary evaluation of the grade of predictable future adherence of the recommendations following this intersociety proposal. The following recommendations are suggested as representing best clinical practice, nevertheless, adoption of local multidisciplinary protocols regarding thresholds of ICP values, drug therapies, hemostasis management and perioperative care of decompressed patients is strongly recommended to improve treatment efficiency, to increase the quality of data collection and to provide more powerful evidence with future studies. Thus, for this future perspective a rapid overview of the role of the multimodal neuromonitoring in the optimal severe TBI management is also provided in this document. It is reasonable to assume that the recommendations reported in this paper will in future be updated by new observations arising from future trials. They are not binding, and this document should be offered as a guidance for clinical practice through an intersociety agreement, taking in consideration the low level of evidence.

Meningiomas as anatomo-pathological entities were first described in the sixteenth century, but it was Harvey Cusching who in 1922 proposed to identify them with the term "meningioma". They are the most common intracranial tumors, occur between middle and late age and prefer female sex. The symptoms depend on their position with respect to the brain regions. These are mostly benign neoplasms, but there are atypical and even malignant forms. Plaque meningioma refers to a specific macroscopic aspect of the meningioma, due to diffuse dural involvement and usually with extracranial extension. We report here a case of plaque convex meningioma with typical grade I. Key Words: En plaque, Meningioma, WHO Meningioma.I meningiomi come entità anatomo-patologiche furono descritti per la prima volta nel XVI secolo, ma fu Harvey Cusching che nel 1922 propose di identificarli con il termine di “meningioma”. Sono i tumori intracranici più comuni, si manifestano tra la mezza e la tarda età e prediligono il sesso femminile. La sintomatologia è funzione della loro posizione rispetto alle regioni dell’encefalo. Si tratta per lo più di neoplasie benigne, ma esistono forme atipiche ed anche maligne. Il meningioma “a placca” si riferisce a un aspetto macroscopico specifico del meningioma, per coinvolgimento durale diffuso e solitamente con estensione extracranica. Riportiamo qui un caso di meningioma convessità en placca con tipico grado I.

In this work the Authors report their experience on the treatment of a case of cavernous venous sinus thrombosis. The diagnosis is clinical and neuroradiological, CT, MRN, cerebral angiography and orbital venography have aided in establishing the diagnosis during life. Very interesting is the therapeutic approach.

Eosinophilic granuloma (EG), Letterer-Siwe disease and Hand-Schuller-Christian disease are collectively called Langherans-cell histiocytosis (LCH). While the latter two are systemic diseases, the former is a localized form of histiocytosis. Solitary EG of the skull are rare lesions characterized by a natural history not well defined yet. In this context, we report a case of a 23-year-old male suffering for a recurrent and progressive right parietal headache. On computed tomography (CT) it was observed an ostelytic lesion which on magnetic resonance imaging (MRI) appeared as an hyperintense soft mass on both T1 and T2 weighted images. The lesion showed a marked and heterogeneous enhancement after gadolinium administration. The surgical excision was complete and the severe headache disappeared. Immunohistochemical analysis of the specimen indicated an eosinophilic granuloma characterized by Ki-67 nuclear antigen expression with a labeling index of 20%. In the pertinent literature we have found two aggressive cases of EG showing the Ki-67 expression with a respectively 6.2% (occipital bone granuloma) and 10% (parietal bone granuloma) labeling index. That high proliferative activity suggests a local Langherans' cell proliferation along with an exuberant inflammatory response and also explains the aggressive clinical course and the rapid expansion of the lesion observed in some rare cases of solitary EG. This is the third case-report of calvarial EG characterized by Ki-67 nuclear antigen expression.

The Authors present a case of rare elbow localization of schwannoma of the median nerve, in 42 year old woman. The surgical treatment and the short follow-up are presented.

The authors report a series of 43 patients suffering from lower limb pain, almost constantly associated with chronic or acute backpain, treated by microsurgical nerve root decompression and by implantation of a soft intervertebral prothesis (DIAM). Satisfying results were obtained in 97% of cases, inducing the authors to consider the device a reliable tool for curing low-back pain and sciatica. Selection criteria are exposed and discussed.

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.We report preliminary results of a prospective study comparing BHC and TDC with suction drainage, in a series of 47 patients randomized into two treatment groups. One group of 22 patients underwent TDC with closed-system drainage and suction reservoir (14 men, 8 women, mean age 78.7 years). Another group of 24 patients underwent BHC with subdural irrigation and closed drainage (16 men, 8 women, mean age 76.3 years). Neurological status was assessed by Markwalder's Grading Scale on admission and at follow-up. All patients underwent computed tomography (CT) before surgery, within 4 days after it, and 1 and 2 months later.Preoperative clinical and radiological data were similar in the two groups. Operating times were shorter in the TDC group, while drainage time was shorter in the BHC group (P0.0001). Length of hospitalization was similar. Recurrence rate, mortality, and neurological recovery were similar, with non significant differences in favor of the TDC group. After 2 months, CT showed complete regression of subdural effusion in 66.6% of cases in the TDC group and in 31.8% in the BHC group (P0.05).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.

In the present review we report a case of a 53-year-old woman affected with a cyst solitary cerebral hemispheric lesion causing acute generalized seizure. Clinical and neuroradiologic diagnosis of cystic astrocytoma was performed and the patient was operated. Microscopic analysis of the surgical specimen led to a diagnosis of parasitic infection, consistent with neurocysticercosis (NCC). NCC is the most frequent parasitosis of the central nervous system (CNS) in the world. The infective agent is taenia solium larvae. It is endemic in Latin America, Africa and some Asiatic countries, such as India. In Europe, many cases have been reported in Portugal, Spain, Poland and Romania. In Italy NCC is a rare disease. In recent years no cases have been described, but with high rate of immigration from endemic areas (Africa and East Europe) this parasitosis will be found in our country too, particularly affecting communities where hygienic conditions are poor. In conclusion we briefly analyze the relationship between pathogenesis of this parasitosis and its clinical symptoms.

A case of encapsulated intracerebral hematoma is described in the light of the relevant literature. The etiopathogenesis, diagnostic problems and treatment of this rare entity are also discussed.
