Abstract
Paragangliomas are usually benign tumors which can be found in many sites of the body, from the base of the skull down to the pelvic floor. In the central nervous system the sellar region is very rarely involved; only three well studied cases have been reported to date. We present the cytological, histological, histochemical, immunocytochemical and ultrastructural features of an intrasellar and suprasellar paraganglioma in an 84-year-old man.

Abstract
Lo xantoastrocitoma pleomorfo è una variante piuttosto rara e relativamente benigna di glioma intracranico che colpisce per lo più soggetti giovani e che mostra una eclatante disparità tra l'aspetto istologico apparentemente maligno e il comportamento clinico invece benevolo. Dopo la prima descrizione di Kepes et al. nel 1979, 71 casi sono stati riportati nella letteratura principale. Il tumore ha una predilezione per i lobi temporale e parietale ed una localizzazione superficiale con coinvolgimento della corteccia, che rende tecnicamente più facile la sua rimozione radicale; è sempre presente un marcato pleomorfismo cellulare, con la coesistenza di più tipi cellulari, insieme con una risposta positiva alla reazione con l'immunoperossidasi (GFAP) e con l'assenza di necrosi. La diagnosi pre-operatoria è generalmente difficile. L'iter terapeutico ottimale si fonda sul trattamento chirurgico, eventualmente reiterato in caso di recidiva, cui può associarsi il trattamento radiante.

Abstract
The outcome of endoscopic endonasal transsphenoidal surgery in 10 patients with pituitary adenomas was compared with that of traditional transnasal transsphenoidal approach (TTA) in 20 subjects. Among the 10 individuals subjected to "pure endoscopy," 2 had a microadenoma, 1 an intrasellar macroadenoma, 4 had a macroadenoma with suprasellar expansion, 2 had a macroadenoma with supra-parasellar expansion, and 1 a residual tumor; 5 had acromegaly and 5 had a nonfunctioning adenoma (NFA). Among the patients subjected to TTA, 4 had a microadenoma, 2 had an intrasellar macroadenoma, 6 had a macroadenoma with suprasellar expansion, 4 had a macroadenoma with supra-parasellar expansion, and 4 had a residual tumor; 9 patients had acromegaly, 1 hyperprolactinemia, 1 Cushing's disease, and 9 a NFA. At the macroscopic evaluation, tumor removal was total (100%) after endoscopy in 9 patients and after TTA in 14 patients. Six months after surgery, magnetic resonance imaging (MRI) confirmed the total tumor removal in 21 of 23 patients (91.3%). Circulating growth hormone (GH) and insulin-like growth factor-I (IGF-I) significantly decreased 6 months after surgery in all 14 acromegalic patients: normalization of plasma IGF-I levels was obtained in 4 of 5 patients after the endoscopic procedure and in 4 of 9 patients after TTA. Before surgery, pituitary hormone deficiency was present in 14 out of 30 patients: pituitary function improved in 4 patients, remaining unchanged in the other 10 patients. Visual field defects were present before surgery in 4 patients, and improved in all. Early surgical results in the group of 10 patients who underwent endoscopic pituitary tumor removal were at least equivalent to those of standard TTA, with excellent postoperative course. Postsurgical hospital stay was significantly shorter (3.1 +/- 0.4 vs. 6.2 +/- 0.3 days, p < 0.001) after endoscopy as compared to TTA.

Abstract
Primary cerebellar germinomas, in the absence of germ-cell tumours outside the nervous system or elsewhere in the cranial cavity and CSF pathways, are exceptional; only two previous cases have been reported in the literature. Two personal observations are described from our 20-year records of intra-axial posterior fossa tumours. The patients were a 32-year-old man and a 17-year-old woman with a clinical history of posterior fossa tumour, studied by computed tomography. The first patient with slight cerebellar signs had a small right hemispheric cerebellar tumour, and the other had a left cerebellar mass with hydrocephalus and progressive intracranial hypertension. Both were treated by tumour removal and irradiation to the whole posterior fossa. The survival times were 58 and 49 months, respectively. The diagnosis of primary cerebellar germinoma cannot be suspected before pathological confirmation. The clinical, neuroradiological and surgical findings are non-specific and quite similar to those of other malignant cerebellar tumours, such as anaplastic gliomas or metastases. Surgery and radiotherapy ensure adequate tumour control in the early stages; cases of recurrence or disseminated disease may be treated by irradiation and chemotherapy.

Abstract
OBJECT This study proposes a topographical classification of spheno-orbital meningiomas. Its aim was to define whether the different intraorbital localizations require different surgical approaches and have different recurrence rates and outcomes. MATERIAL AND METHODS Sixty patients with spheno-orbital meningiomas operated upon between 1983 and 2003 were reviewed. Four types were identified according to the extent of intraorbital tumor invasion: I: lateral or superolateral (15 cases); II: medial and inferomedial (8 cases); III: orbital apex (25 cases); IV: diffuse (12 cases). Three surgical approaches were used: lateral orbitotomy (15 cases with lateral or superolateral tumors), supraorbital-pterional approach (42 cases, including all 8 inferomedial cases, all 25 orbital apex cases, and 9 of 12 diffuse tumors), and a fronto-temporal-orbitozygomatic approach (only 3 cases with diffuse meningiomas and large-scale tumor invasion in the infratemporal fossa and cavernous sinus). RESULTS Tumor removal was complete (Simpson grades I and II) in 40 cases, and incomplete in 20 (33.3%). There were two postoperative deaths (3.3%). A sufficient clinical follow-up was obtained in 52 cases. The clinical outcome was excellent in 26 patients (50%), good in 16 (30.8%), moderate in 6 (11.5%), and poor in 4 (7.7%). Twenty-two of 52 patients (42.3%) had tumor recurrence; however, 44 (84.6%) achieved tumor control after surgery alone through two or more operations. The recurrence rate was correlated with the Simpson grade of resection and the intraorbital tumor location. Significantly higher rates of recurrence were recorded for the orbital apex type (50%) and diffuse forms (60%), than for the inferomedial (28.5%) and superolateral forms (23%). CONCLUSIONS Spheno-orbital meningiomas may be classified according to the location and extent of the intraorbital tumor invasion. The different localizations may require different surgical approaches, with different chances of complete removal. The location and extent of the intraorbital tumor results in different recurrence rates, lower for superolateral and inferomedial forms than for orbital apex and diffuse forms.

Abstract
OBJECT Lesions located in the retroclival area and at the level of the cranio-vertebral junction are typically approached through a variety of anterior, antero-lateral and postero-lateral skull-based approach, either alone or in combination. The aim of this anatomical study was to demonstrate the possibility of an endoscopic endonasal approach to the clivus and cranio-vertebral junction. MATERIALS AND METHODS Five fresh cadaver heads injected with colored latex were used. A modified endonasal endoscopic approach was made through two nostrils in all cases. Endoscopic dissections were performed using rigid endoscopes, 4 mm in diameter, 18 cm in length, with 0 degrees lenses. RESULTS Access to the clivus was possible using a lower trajectory when compared to that necessary for the sellar region. The sphenoid sinus is entered, and its inferior wall is completely removed, permitting the union of the sphenoidal and rhinopharyngeal parts of the clivus. The entire clivus can be removed, and the cranio-vertebral junction is opened, removing the anterior arch of atlas and the odontoid process. After the opening of the dura, the anterior surface of the pons and upper spinal cord with corresponding nerves and vasculature are visible. CONCLUSION The endoscopic endonasal approach to the clivus and cranio-vertebral junction could be a valid alternative for surgical treatment of anterior lesions of these regions. Adequate endoscopic skill, lab training on cadavers and dedicated tools are required for clinical applications of the approach.

Abstract
BACKGROUND Endoscopic endonasal transphenoidal surgery has been recently proposed as a minimally invasive procedure for the treatment of pituitary adenomas. The main objective of the anaesthesiologist is to induce sufficient haemodynamic control together with rapid recovery at the end of surgery. The aim of this study was to examine recovery profile, surgical operative conditions and haemodynamic differences using remifentanil infusion with either propofol target controlled infusion system or sevoflurane. METHOD Forty-four adult patients were enrolled in a prospective, randomized, single-blind, two-group study: Group P received propofol target controlled infusion system and remifentanil; Group S received sevoflurane and remifentanil for maintenance of anaesthesia. RESULTS No statistically significant differences between the two groups with regards to the haemodynamic changes, operative conditions as assessed by a four-step bleeding score (0-3), were obtained. Recovery times were considerably shorter after remifentanil-sevoflurane in comparison with remifentanil-propofol target controlled infusion system group (7.4 vs. 12.8 min, P < 0.01). CONCLUSION This study demonstrates that sevoflurane-remifentanil gives a faster recovery and equivalent intraoperative status compared with propofol target controlled infusion system with remifentanil for the endoscopic endonasal transphenoidal approach.

Abstract
OBJECTS This study was made to define the mechanism of endoscopic third ventriculostomy (ETV) in the various forms of hydrocephalus. METHODS One hundred and forty patients with various forms of hydrocephalus treated by ETV are reviewed. The series includes 75 cases (53.5%) of triventricular obstructive hydrocephalus (group 1), 20 (14.3%) with hydrocephalus following CSF infection or hemorrhage (group 2) and 45 (32.3%) with idiopathic normal pressure hydrocephalus (group 3). Factors which have been considered include type and etiology of the hydrocephalus, intraoperative evidence of downward and upward movement of the third ventricular floor after the stomy, patient outcome and rate of shunt-independent cases. RESULTS The overall rate of successful ETV was 79.3% (111/140 shunt-free patients). The success rate was 88% (66/75) in group 1, 60% (12/20) in group 2 and 73.4% (33/45) in group 3. The intraoperative finding of significant movement of the third ventricular floor after the stomy was evidenced in 121/140 cases (86.4%) and particularly in all cases of group 1, in 9/20 (45%) of group 2 and in 37/45 (82%) of group 3. CONCLUSIONS The relatively high rate of success of ETV in various forms of hydrocephalus and the intraoperative finding of mobility of the third ventricle floor after the stomy suggest that the first mechanism of the ETV is the restoration of pulsatility of the ventricular walls. This results in restoration of the CSF flow from the ventricular system into the subarachnoid spaces and normalization of the CSF dynamics. Accordingly, ETV is not only an internal shunt, but it primarily influences the capacity of the brain pulsatility to ensure CSF flow.

Abstract
Oligodendrogliomas are brain tumors with unpredictable biological and clinical behavior. Prognostic factors related to survival are still controversial. The present study reviews 50 patients with well-differentiated (WHO grade II) oligodendrogliomas, located in the cerebral hemispheres and operated upon between 1980 and 1998. Prognostic factors studied include patient's age and sex, tumor location and extent, preoperative KPS, and extent of the surgical resection. The Ki-67 and the proliferative cell nuclear antigen (PCNA) levels were studied in all patients and some growth factors (GFs), including vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), platelet-derived growth factor (PDGF) and tenascine were examined in 20 patients. The long-term outcome and survival are not significantly correlated with the patient's age and sex, tumor location and extent, preoperative KPS and procedure for resection. Patients with lower Ki-67 and PCNA showed a significantly longer survival time (p < 0.001 and p < 0.019, respectively). Between 45 and 70 % of the tumors stained positive for one or more growth factors. Interestingly, cases with late recurrences (more than 4 years after surgery) and longer survival are significantly associated to negative GF expression or slight positivity, as compared with the variable and more often moderate immunoreactivity of cases with early anaplastic recurrences and shorter survival time. The presented data suggest that low proliferation indices and negative GF expression are associated with longer survival in well-differentiated oligodendrogliomas.

Abstract
OBJECTIVE To report a series of 18 patients who underwent microsurgical repair of the facial nerve using different techniques and to discuss the indications and results of facial reinnervation procedures. METHODS Eighteen patients with post-surgical facial palsy underwent facial reinnervation using different techniques.'These included classic hypoglossal-facial anastomosis in 13 cases, one-stage hemihypoglossal-intratemporal facial nerve anastomosis and translabyrinthine removal of residual intra-canalar acoustic schwannoma in 3, hemihypoglossal-facial nerve anastomosis in one, and neurotization of facial muscles through a nerve graft in one. RESULTS The facial muscle function improved in all patients, up to grade III in 7 cases (39 %), grade IV in 9 (50 %) and grade V in 2 (11 %). The tongue atrophy was minimal in 70.5 %, moderate in 17.5 % and severe in 12 %. The outcome was better in younger patients (less than 40 years of age) and in those with a lesser grade of preoperative facial impairment. CONCLUSIONS The classic hypoglossal-facial anastomosis is the technique of choice in most cases. The use of the intratemporal facial nerve is indicated when removal of an intra-canalar residual schwannoma must also be performed. The neurotization of the facial muscles through a nerve graft may be used when there is no distal trunk of the facial nerve available for the anastomosis.

Abstract
Pegvisomant, a GH receptor antagonist, is a new pharmaceutical approach to acromegaly. It enables IGF-I levels to return in the age- and sex-reference range in approximately 90% of patients. This new approach is particularly beneficial in those patients who do not experience control of hormone hypersecretion after surgery and/or medical treatment with somatostatin analogs. In our preliminary experience, out of 16 patients unsuccessfully operated on by transsphenoidal surgery and resistant to 40-mg octreotide-LAR or 120-mg lanreotide for at least 6 months, 13 normalized their IGF-I levels within 6 months from treatment beginning. Normalization of IGF-I levels was accompanied by a significant decrease of ring size. We did not observe any increase of tumor remnant in this short period of treatment. In two cases we observed a significant increase of liver transaminases levels. In conclusion, more than 80% of patients with acromegaly unsuccessfully treated by surgery or currently available somatostatin analogs can achieve normal IGF-I levels after short-term treatment with pegvisomant.

Abstract
The endoscopic endonasal transsphenoidal approach has been proposed in the past decade as a minimally invasive surgical technique for the removal of pituitary tumors. From January 1997 to November 1999, 100 consecutive patients with pituitary tumors underwent endoscopic endonasal surgery, according to Jho's technique. We employed 0 degrees, 30 degrees, 45 degrees, and 70 degrees rigid endoscopes, 18 - 30 cm in length, 4 mm in diameter with an outer sleeve for irrigation and secured to a holder. Among the 87 pituitary adenomas, tumor removal was total in 51, subtotal (> 80 %) in 20 and partial in 16 cases. Four craniopharyngiomas were totally removed and an intra-suprasellar arachnoid cyst was emptied; a biopsy was performed in the two patients with a clivus chordoma. The two cases of sphenoid sinusitis were cured by surgery, the three patients with spontaneous CSF rhinorrhea were successfully treated and the residual nasal meningocele was removed. The endoscopic endonasal transsphenoidal approach appeared to be less traumatic than the traditional microsurgical approach, was very effective, and was characterized by a reduced number of complications. However, the relatively small series together with the short follow-up do not allow us to draw definitive conclusions. The post-operative reduction in hospital stay (two days in 40 of 100), significantly reduced the cost of patient's management.

Abstract
OBJECTIVES We describe three patients with symptomatic septum pellucidum cysts treated by endoscopic fenestration and discuss the different endoscopic approaches to these cysts. CLINICAL PRESENTATION The patients are an 8-year-old boy, a 7-year-old boy and a 21-year-old woman; this last also had a right frontal cavernous angioma and a pituitary microadenoma. All patients presented with headache, associated with vomiting in two and behavioral changes in one. In all cases magnetic resonance showed a septum pellucidum cyst. INTERVENTION Two patients were operated upon by posterior approach through a right occipital burr hole and underwent fenestration from the right occipital horn to the cyst, with a second fenestration from the cyst to the left lateral ventricle in one. Another patient underwent microsurgical removal of a right frontal cavernoma and endoscopic cyst fenestration with both lateral ventricles through a right frontal craniotomy. Postoperatively, headache and vomiting resolved in all cases and behaviour changes improved in one. CONCLUSIONS Endoscopic fenestration is the treatment of choice for septum pellucidum cysts, where it results in immediate relief of the mass effect of the cyst and in the remission of the associated symptoms. We suggest a posterior approach through a right occipital burr hole. It allows one to easily cannulate the occipital horn, which is usually larger than the frontal one, thus avoiding the risk of damaging the vascular and neural structures surrounding the foramen of Monro. Besides, the endoscopic trajectory is in our opinion more direct. The two-window technique, with fenestration of the cyst into both lateral ventricles, improves the chances of long-term patency.

Abstract
OBJECTIVE To describe a simple method of sellar reconstruction after endoscopic endonasal transsphenoidal surgery that will allow rapid watertight closure of the sellar floor. METHODS A bent sheet of a polyester-silicone dural substitute, fashioned for this purpose with scissors, is introduced into the sella after removal of the lesion. Because of the consistency of the sheet, it opens spontaneously and becomes stuck. Autologous fat tissue or gelatin foam is positioned thereafter, followed by another layer of the dural substitute; a film of fibrin glue completes the sealing. RESULTS Fifteen patients underwent this method and no postoperative cerebrospinal leak or other complication was experienced. CONCLUSION This easy method of sellar reconstruction represents an effective and fast possibility to perform the final step of the endoscopic transsphenoidal procedure, which otherwise may cause maneuverability problems in the limited space of one nostril.

Abstract
The endoscopic endonasal transsphenoidal approach to the sellar region for the removal of pituitary adenomas and of other neoplasms in the same area has proved its reliability and effectiveness for the very wide vision it offers, coupled with minimal surgical trauma. Indications and advantages of such a technique are reported, focused on the treatment of lesions of the sellar and parasellar environment in pediatric age-group patients, and based on a consecutive series of 100 patients, 3 of them adolescents, treated during the last 3 years.

Abstract
Despite a good cure rate after surgery, the recurrence rate in pituitary adenomas is globally high. The decision making in such cases can be problematic for the nature of the lesion, for the anatomic structures involved, for the different pharmacological, surgical, radiotherapeutic and radiosurgical options nowadays available. In the perspective of an improvement and refinement of the surgical procedure an endoscopic endonasal transsphenoidal approach to the pituitary was recently adopted in the Neurosurgical Department of the University of Naples. Its minimal invasiveness and its wider and direct anatomic control of the operative field has allowed a faster, greater and safer potential of tumour excision, with respect of the sphenoid, sellar and parasellar structures. The authors have examined the advantages provided by this technique in 12 patients with recurrent pituitary adenomas and in 2 craniopharyngiomas already treated via a transnasal transsphenoidal approach (TTA), where the anatomy of surgical field had been distorted by the first operation or the radiation therapy. They conclude that the endoscopic transsphenoidal re-operation might be considered the procedure of choice in case of recurrences and its easiness in such conditions could favour its larger use, before other more aggressive therapeutic solutions.

Abstract
A microanatomical study has been designed to investigate the pattern of arrangement of the sympathetic fibres inside the cavernous sinus. The course of these fibres has been examined in 60 fresh specimens of parasellar region from autopsy cadavers. Apart from the thin branches arising at different intervals along its course, the sympathetic plexus of the carotid artery gives rise to a large division that usually joins the abducens nerve and leaves it to combine with the ophthalmic branch of the fifth. In 10% of specimens we have found a direct connection between sympathetic fibres and the ophthalmic branch of the trigeminal nerve. We did not recognise similar connections with oculomotor and trochlear nerves.

Abstract
TECHNIQUE Endoscopic transsphenoidal surgery. New, developing, minimally invasive technique. Removal of pituitary lesions and tumors of the parasellar region. TECHNICAL DEVELOPMENT Endoscopic endonasal transsphenoidal surgery. Endonasal, not transnasal, procedure. Great respect of anatomy. Very wide surgical field, without intraoperative use of a nasal speculum, but with less room in which to work (only one nostril) and potential conflict between the surgeon's hands and the endoscope (both when entering the nostril and while working inside). INSTRUMENTATION New instrument. Secure grip. Barycenter of the instrument is the surgeon's hands. Many different tips with different functions. Elimination of the bayonet-like shape. Handle bent in the horizontal plane to avoid interference with the surgeon's hands and to allow the distal, thin part of the instrument to be used safely and comfortably.

Abstract
Diaphragma sellae meningiomas are unusual tumours often not distinguished from pituitary macroadenomas. Preoperative differentiation is essential, because the trans-sphenoidal approach is used for surgical removal of adenomas, while meningiomas are approached via a craniotomy. We reviewed five patients in whom a diaphragma sellae meningioma was initially diagnosed as a nonsecreting pituitary macroadenoma. MRI criteria for differential diagnosis are discussed. The main findings considered are visibility of the pituitary gland, contrast enhancement, the centre of the lesion and sellar enlargement. These criteria, applied to a blind review, allow correct identification of the tumours.

Abstract
Standard microscopical transsphenoidal surgery is used world-wide in most sellar lesions, but continuing technological progress leaves room for further possibilities. The authors have employed a slightly modified Jho-Carrau technique for endoscopic endonasal transsphenoidal removal of pituitary lesions. This approach has been successfully used in 15 consecutive patients; the preliminary results are reported. The advantages and the limitations of this technique are discussed and compared to standard transsphenoidal surgery. In consideration of the low invasiveness of this approach and of the improved respect for the inner nose and sinus structures, the authors suggest the new term of Functional Endoscopic Pituitary Surgery (FEPS) to characterize this simple one-nostril endoscopic endonasal procedure.

Abstract
The effect of surgery alone or followed by radiotherapy in recovering visual abnormalities, debulking tumor mass and restoring hormone impairments was evaluated in 84 patients with clinical nonfunctioning pituitary adenomas (NFPA) subjected to 1-10 yr follow-up. All patients underwent surgery via transsphenoidal (in 69) or transcranic-pterional approach (in 15). Radiotherapy was performed after surgery in 59 of 72 patients with incomplete tumor removal. The assessment of pituitary function was performed in all patients before and every 1-2 yr after surgery and/or radiotherapy. Radiological and ophthalmologic assessment was performed before and 3, 6 and 12 months after surgery, then yearly. At diagnosis, headache and visual disturbances occurred in 63 and 58 patients, respectively, while deficiency of GH, TSH, ACTH, FSH, LH and ADH was documented in 55, 7, 19 47 and 6 patients, respectively. After surgery, gonadal function recovered in 12 women, visual disturbances improved in 43 patients (15 regained normal vision), pituitary function improved in 8 of 62 patients, worsened in 34 patients. At MRI, complete tumor removal was documented in 12 of 84 patients. After surgery alone, tumor regrowth was observed in 7 patients between 3-7 yr. After radiotherapy, vision improved in 9, remained unchanged in 49 and worsened in 1 of 59 patients. After radiotherapy, tumor regrowth was documented in 9 patients between 2-12 yr and the prevalence of hypopituitarism raised from 28.8% to 92% after 1 and 10 yr. In conclusion, surgery alone is effective only in a minority of patients (14.3%) and radiotherapy causes hypopituitarism in rather the totality of patients after 10 yr. The prevalence of tumor regrowth was similar in irradiated ones (15%) and non irradiated patients (28%; chi(2), p = 0.4). Therefore, a careful radiological followup is suggested after surgery so that radiotherapy can be performed promptly on the basis of clinical data, tumor regrowth and/or invasiveness documented at histology.

Abstract
Pretreatment with octreotide (OCT) in acromegaly has been reported to improve surgical outcome. The objective of this study was to analyze retrospectively the effects of a 3- to 6-month presurgical treatment with OCT in acromegalics focusing on electrocardiographic (ECG) records, blood pressure levels, glucose and lipid profile, tumor size and consistency, easy tumor removal at surgery, and morphological findings at pathology. Fifty-nine patients with acromegaly who were undergoing surgical treatment were studied randomly before surgery; 37 patients were untreated, and 22 were treated with OCT at doses ranging 150-600 micrograms/day for 3-6 months. At study entry, untreated and OCT-treated patients had similar circulating GH and insulin-like growth factor I (IGF-I), glucose, and cholesterol levels as well as prevalence of overt diabetes mellitus, hypertension, and ECG abnormalities. In untreated and OCT-treated patients, respectively, radiological imaging documented microadenoma in 0 and 1, intrasellar macroadenoma in 10 and 6, intra- and suprasellar macroadenoma in 18 and 11, invasive macroadenoma in 9 and 4 patients. Before surgery, serum GH and IGF-I levels significantly decreased in the 22 OCT-treated acromegalics, and in 5 of them, a significant shrinkage was documented. ECG abnormalities disappeared in 7 of 11 (63.6%) OCT-treated patients. In 3 of the 7 patients with diabetes mellitus, treatment with OCT together with low carbohydrate intake normalized blood glucose levels, whereas in 2 patients, insulin could be replaced by oral antidiabetics, and in 2 patients, the insulin dose was reduced. Presurgical blood glucose, total cholesterol and triglyceride levels, as well as systolic (145.2 +/- 3.4 vs. 132.9 +/- 2.5 mm Hg; P < 0.01) and diastolic (94.3 +/- 1.7 vs. 84.3 +/- 1.6 mm Hg; P < 0.001) blood pressure levels were significantly higher in untreated than in OCT-treated patients. Two weeks after surgery, circulating GH and IGF-I levels were normalized in 11 untreated (29.7%) and 12 OCT-treated (54.5%) patients (P < 0.005, by chi 2 test). Macroscopically, no difference was found between untreated and OCT-treated adenomas, whereas at pathology, a significant increases in cellular atypia (31.6% vs. 19.2%; P < 0.05) was found in OCT-treated adenomas. One patients in the untreated group died from cardiorespiratory arrest during the early postoperative period. Finally, the average duration of hospitalization after operation was longer in untreated than in OCT-treated patients (8.6 +/- 0.7 vs. 5.6 +/- 0.5 days). We conclude that a 3- to 6-month treatment with OCT before surgery for GH-secreting adenoma improved clinical conditions and surgical outcome and reduced the duration of hospitalization after operation.

Abstract
Epilepsy is the most frequent presenting sign in patients with cavernous angiomas and is the major cause of morbility. Persistence of seizures after surgical treatment prompted many authors to examine the possibility of removing the cavernoma and the surrounding tissue. In our series of 53 cavernous angiomas, all the 35 patients with preoperative seizures underwent surgery by means of lesionectomy alone. One hundred percent of patients with less than five preoperative seizures and/or an history under 12 months was seizure free, while only 62.5% of patients with more than five seizures and/or an history longer than 12 months was seizure free. Number and duration of seizures before surgery seems to be the most important factor in the seizure outcome after surgical treatment.

Abstract
BACKGROUND Hemangiomas are benign vascular tumors. Because less than 1% of all hemangiomas are intramuscular, only 8 cases of temporal muscle hemangioma have been described to date. This is a case study of a 13-year-old girl who was referred to our institution because of a soft swelling located in the left temple that has enlarged progressively since birth. METHODS CT scan, angiography and MRI showed a tumor mass lying in the temporal muscle, with homogeneous contrast enhancement. No tumor blush or feeding arteries were detected. At surgical exploration, the tumor appeared to be well demarcated. It was totally excised, sparing the surrounding temporal muscle, which did not present any sign of infiltration. Histopathologic examination showed the lesion to be a cavernous hemangioma. RESULTS The cosmetic result was excellent, and MRI after 1 month and 2 years showed complete absence of the lesion and no evidence of recurrence. CONCLUSIONS Although this type of tumor may be treated by various methods surgical excision yields the best results in the short and the long term. The surrounding tissue is spared as much as possible when no signs of infiltration are noted at operation, especially when involving small and functionally important muscles, as in our case.

Abstract
The fissure separating the motor from the sensory cortex and the substantia gelatinosa capping the posterior horn of the spinal cord are still known by the name of the Italian anatomist Rolando, Luigi Rolando was born in Turin, Italy, in 1773 and died in 1831. His life was not easy, the first of his problems being the death of his father when Rolando was still very young. Three people were to be influential in his life and career: Father Maffei, his maternal uncle who raised him; Dr. Cigna, the anatomy professor who discovered his talent; and Dr. Anformi, a general practitioner who introduced him to the practice of medicine and to the best circles of the city. Forced to leave Turin by the Napoleonic invasion of the country, Rolando first stopped in Florence, where he learned about anatomical dissection, drawing, and engraving and studied the appearance of nervous tissue under the microscope. Later he went to Sardinia where, although cut off from European cultural circles, he developed his major theories. Rolando pioneered the idea that brain functions could be differentiated and located in specific areas and discovered the fixed pattern of cerebral convolutions, highlighting motor and sensory gyri. He demonstrated the complexity of the central gray matter of the spinal cord, describing the "substantia gelatinosa," and he deduced that nervous structures are connected in a network of nervous fibers linked by electrical impulses. Rolando had to struggle for recognition, however, as the priority of his discoveries was challenged by the almost contemporaneous work of Gall and Spurzheim on cerebral localization and of Flourens on cerebellar function. Nevertheless, his efforts contributed greatly to the clarification of brain function. His observations on nervous anatomy have been especially accurate, as shown by the nomenclature "fissure of Rolando."

Abstract
Tumours of the callosal area are quite common. However, those primarily located in this region which remain confined within the corpus callosum area not frequent. The introduction of intraoperative location devices, coupled with preoperative MR, CT and angiography, has further enhanced the operability of lesions of the deep area around the callosal body. On the basis of their site of origin, three groups of tumours can be identified: tumours originating from the corpus callosum (defined as properly callosal); tumours secondarily invading the corpus callosum; tumours affecting the corpus callosum because of their surgical approach. Various routes have been developed to reach the callosal area, the site and direction of growth of the tumour providing indications for the preferred approach. The commonest routes are the following: interhemispheric approach; transcerebral approach; transcallosal approach; the transcallosal approach to the ventricles offers a valuable corridor in the management of intraventricular tumours. It provides a rapid and safe access, without the attendant epilepsy that often follows the transcortical approach. The neuro-psychological effect of callosotomy are minimal and not affecting the daily activities of patients. Thus it is possible to reach remote regions through a narrow entry with very low neuro-psychological impact.

Abstract
The case is reported of a patient bearing a pterional meningioma on the right (non-dominant) side manifesting with ipsilateral motor symptoms, completely recovered after tumor removal. The occurrence of ipsilateral sensory and/or motor symptoms, probably due to direct or indirect involvement of the sensory/motor secondary areas of the insula of Reil, may be misleading in diagnosis because of apparent incongruity between clinical presentation and radiological findings. Only seven cases of such a condition, all localized on the left (dominant) side, have been previously reported.

Abstract
A ten-year experience on 36 patients bearing macroprolactinomas (MP) and 86 others bearing microprolactinomas (mP) is reported in this study. Different therapeutical approaches were used: 1) trans-sphenoidal surgery in 24 patients with MP and in 25 with mP; 2) medical therapy with the oral form of bromocriptine (BRC) in all the 24 patients with MP previously subjected to surgery, in 48 patients with mP ab initio, and in 16 out of 25 patients with mP previously subjected to surgery; 3) medical therapy with the long-acting injectable forms of BRC in 12 MP- and 13 mP-bearing patients, and 4) conventional radiotherapy in 12 of the 24 patients with MP previously subjected to surgery. The follow-up, performed five years after surgery, showed that: a) all the 24 patients with MP but one had normal PRL levels during BRC administration, with a rebound of hyperprolactinemia in all cases after withdrawal; b) during the treatment BRC caused normalization of PRL in 15 of the 16 mP-bearing patients surgically treated and in all the 48 mP-bearing patients only treated with BRC; c) in 20 of the 25 patients the treatment with injectable retard BRC caused the normalization of plasma PRL and the shrinkage of the tumor mass in all the patients with MP but one, as revealed by seriate CT scans. In conclusion, the surgical treatment of prolactinomas was ineffective to normalize plasma PRL levels in most patients whereas BRC, in standard or in retard forms, was able to normalize plasma PRL levels, reduce the tumoral mass and preserve the pituitary residual tissue. BRC should be, therefore, used as first choice therapy both for MP and mP.

Abstract
To examine the reliability of the diagnoses reached on multiple small fragments of cerebral glial tumors obtained via stereotactic biopsy, samples obtained from 100 consecutive glial tumors (during real or simulated biopsy) were studied by cytology and histology. In comparison to the definitive diagnosis made on the whole tumor, a correct positive diagnosis on the biopsy sample was made by histology in 96% of cases and by cytology in 93% of the cases (with 96% correct results when combining both methods). A correct identification of the tumor type and grade was achieved by histology in 82% of cases and by cytology in 80% of the cases (with 85% correct results when combining both methods). The limits of stereotactic biopsy are related to the difficulty of identifying all of the typical tumor features on tiny tissue fragments of a pleomorphic neoplasm, such as a glioma. This study demonstrates that better results may be obtained by using both cytology and histology to study multiple stereotactic biopsy samples from glial tumors.

Abstract
Patency of vascular microanastomosis was examined in aging (6 months) and hypercholesterolemic rats, reproducing conditions similar to those occurring in human pathology. Results have been compared with those achieved in normocholesterolemic, younger (aging less than 8 weeks) rats.

Abstract
Two cases of pituitary adenoma associated with a parasellar cyst are reported; only one similar case has been described previously. Even though such an association may be coincidental, a pathogenetic relationship between the two lesions in one of our cases may be assumed: shrinkage of the prolactin-secreting pituitary adenoma by means of bromocriptine therapy did, in fact, cause collapse of the cyst. Such an occurrence must not be disregarded in considering the therapeutic approach.

Abstract
Inversion and prolapse into the sella of the superior capsule and the diaphragma sellae is the only condition that warrants, at least macroscopically, radical removal of tumors with suprasellar extension operated on via the transsphenoidal route. If this does not occur spontaneously, air can be introduced into the subarachnoid space through a lumbar spinal catheter to produce forced dissection of the suprasellar cisterns and collapse of the tumor capsule ("pumping technique"). This method permits complete removal of the neoplastic tissue. In a series of 124 transsphenoidal operations for tumors with suprasellar extension, spontaneous descent of the capsule occurred in only 26 cases. Forced dissection using air distension of the cisterns was carried out in 88 cases, with complete success in 56 cases, partial success in 20, and no effect in 12. There were no complications or unwanted side effects in any patient.

Abstract
A 62-year-old man underwent percutaneous balloon catheter compression of the gasserian ganglion for typical trigeminal neuralgia. After this, a subarachnoid hemorrhage was discovered and normal pressure hydrocephalus developed, which required shunting. Although the neurological function recovered, the patient died 8 months later because of supervening hepatic insufficiency, probably caused by protracted antibiotic therapy. Such a fatal complication, the first one associated with the technique of percutaneous trigeminal compression, was perhaps predisposed by preexistent cerebral atrophy with enlargement of the subarachnoid spaces; the unforeseen piercing of the dilated trigeminal cistern probably permitted the intracranial subarachnoid diffusion of an otherwise trivial hemorrhage. The safety of the procedure may be greatly reduced in such instances.
