Abstract
Background Isolated cavernous malformation (CM) of the abducens nerve has not been reported in the literature. Herein, the authors address the clinical importance of these lesions and review the reported cases of CM from 2014 to 2020. Case Description A 21-year-old man presented with binocular diplopia and headache from 2 months before his admission. The neurological examination revealed right-sided abducens nerve palsy. The brain MRI revealed an extra-axial pontomedullary lesion suggestive of a CM. The lesion was surgically removed. During the operation, the abducens nerve was resected considering the lesion could not be separated from the nerve and an anastomosis was performed using an interposition nerve graft and fibrin glue. Pathological examination of the resected lesion revealed that it was originated from within the nerve. The patient's condition improved in postoperative follow-ups. Conclusion Surgical resection of the cranial nerves CMs is appropriate when progressive neurological deficits are present. If the lesion is originated from within the nerve, we suggest resection of the involved nerve and performing anastomosis. Novel MRI sequences might help surgeons to be prepared for such cases and fibrin glue can serve as an appropriate tool to perform anastomosis when end-to-end sutures are impossible to perform.

Abstract
AIM Currently, there are many different surgical approaches to orbital pathology. This pathology rarely occurs in neurosurgical practice, and neurosurgeons have often used approaches that can be accompanied by negative cosmetic and functional outcomes. MATERIAL AND METHODS We present a case report of orbital cavernoma removal via a minimally invasive approach. RESULTS The presented case demonstrates successful removal of orbital cavernoma using the transpalpebral approach: a skin incision along a natural fold of the upper eyelid and orbitofrontal keyhole craniotomy. In the postoperative period, existing symptoms regressed; the patient assessed the cosmetic effect as excellent. CONCLUSION The transpalpebral keyhole approach can be an excellent alternative to traditional approaches to orbital cavernomas. This approach demonstrated its efficacy and safety in skull base surgery and provided excellent functional and cosmetic outcomes.

Abstract
Cavernous hemangiomas are not true vascular tumors, but rather are slow-flow venous malformations (VMs). They are present at birth as nonproliferating vascular birthmarks composed of anomalous ectatic venous channels. VMs have often been incorrectly called cavernous hemangiomas and cavernous angiomas. These terms have for a long time lead to confusion with the more common proliferating or true hemangioma of infancy. VM has been reported to arise at all sites including skin and subcutaneous layers of the head and neck, face, extremities, liver, gastrointestinal tract, and even the thymus. Although VMs are common intraocular tumors and are involved within intracranial, extraaxial cranial nerves within the cavernous sinus has been sporadically reported, and less often in the supraorbital nerve, an extraocular and extracranial division of the trigeminal nerve has not been reported. The authors present an extremely rare occurrence of VM involving the supraorbital nerve in an 80-year-old female.

Abstract
Intracranial cavernous angiomas (CAs) are hamartomatous vascular malformations consisting of thin-walled vascular channels located within the brain, but typically lacking intervening neural parenchyma, large feeding arteries, or draining veins. The CAs occurring in the ventricular system are rare, with an incidence of 2.5% to 10.3% of the intracranial CAs, and those arising from the trigone of the lateral ventricle are even rarer. Till now, there are <20 patients with trigonal CAs have been reported in the English literature. In this study, the authors describe an extremely rare case of multiple intracranial CAs with a trigonal CA mimicking glioma. Furthermore, they also discuss the characteristic aspects of symptoms, radiologic findings, diagnosis, and treatment of this benign lesion.

Abstract
The goals of this study were to analyze the incidence, clinical manifestations, neuroimaging findings, surgical treatments, and neurological outcomes of trigonal cavernous malformations (TCMs). Among 1395 cases of intracranial and intraspinal cavernous malformations (CMs) surgically treated between 2003 and 2016 at Beijing Tiantan Hospital, a series of 12 patients with TCM was chosen for analysis and their records were reviewed. We also performed an exhaustive literature search using PubMed to identify all previously reported cases in the literatures. TCMs accounted for 0.86% of the entire series of the central nervous system (CNS) CMs. The case series consisted of five male and seven female patients (ratio 1:1.4), with an average age at presentation of 32.9 years (7-53 years). In all the cases, headache was the most common initial symptom (66.7%). Complete resection without surgical mortality was achieved in all the cases. Postoperative complications included fever, lower limb weakness, sensory aphasia, and calculational capacity declination. Follow-up period after diagnosis was 15 to 74 months (mean 48.3 months); no patient was lost to follow-up. All the patients were considered to be in excellent clinical condition. TCMs are rare lesions; they can reach large size, and their symptoms and signs commonly resulted from mass effect. Surgical intervention is the treatment of choice for TCMs; patients can obtain favorable neurological outcomes after complete resection.

Abstract
Cavernous malformations, accounting for approximately 5-15% of all vascular abnormalities in the central nervous system, are angiographically occult lesions which most often present with seizures, rather than acute hemorrhage. Widely variable across populations, the incidence of cavernous malformations has been reported to be 0.15-0.56 per 100 000 persons per year, with an annual hemorrhage rate of 0.6-11% per patient-year. Seen in 0.17-0.9% of the population, up to one-half are familial, and at least three gene loci have been associated with a familial form, more common among Hispanic Americans. Most cavernous malformations are supratentorial, with 10-23% in the posterior fossa, and approximately 5% found in the spine.

Abstract
Cavernous malformations are low-flow vascular malformations that are histologically characterized by the lack of mural elements of mature vascular structures and intervening parenchymal neural tissue. They are often clinically quiescent, and may grow, bleed, and regress, but can also manifest clinically as neurologic deficits or seizures in the setting of an acute hemorrhage. The low-flow nature of cavernous malformations renders them inherently occult on cerebral angiography. Magnetic resonance imaging has become the mainstay imaging modality in evaluating cavernous malformations, producing characteristic imaging features that usually provide a straightforward diagnosis. Features on magnetic resonance imaging include a reticulated pattern of mixed hyper- and hypointensity on T1- and T2-weighted imaging, with a characteristic hypointense rim best appreciated on T2-weighted imaging or gradient-echo sequences. Contrast enhancement is useful for revealing coexisting developmental venous anomalies that are frequently associated with sporadic cavernous malformations, and may further support the diagnosis. Susceptibility-weighted imaging is highly sensitive for cavernous malformations and accompanying developmental venous anomalies, and is superior to gradient-echo sequences in screening for multifocal, familial cavernous malformations.

Abstract
BACKGROUND Among the rare intraventricular cavernomas, purely intra-aqueductal cavernomas are exceptionally rare. CASE DESCRIPTION A 62-year-old patient presented with progressive headache, memory loss, gait instability, and urinary incontinence. Magnetic resonance imaging showed the presence of a mass lesion located in the lumen of the cerebral aqueduct, associated with triventricular hydrocephalus. CONCLUSIONS We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intra-aqueductal lesion, make the diagnosis of cavernoma, and treat symptoms resulting from hydrocephalus without increasing the risk of bleeding.

Abstract
Few case reports of encapsulated intracranial hematoma (EIH) exist, and the mechanisms underlying the onset and enlargement of EIH remain unclear. Here, we report on a 39-year-old woman with an EIH that repeatedly hemorrhaged and swelled and was ultimately surgically removed. In June 2012, the patient visited her local doctor, complaining of headaches. A magnetic resonance imaging (MRI) scan identified a small hemorrhage of approximately 7 mm in her right basal ganglia, and a wait-and-see approach was adopted. Six months later, her headaches recurred. She was admitted to our department after MRI showed tumor lesions accompanying the intermittent hemorrhaging in the right basal ganglia. After admission, hemorrhaging was again observed, with symptoms progressing to left-sided hemiplegia and fluctuating consciousness; thus, a craniotomy was performed. No obvious abnormal blood vessels were observed on the preoperative cerebral angiography. We accessed the lesion using a transcortical approach via a right frontotemporal craniotomy and removed the subacute hematoma by extracting the encapsulated tumor as a single mass. Subsequent pathological examinations showed that the hematoma exhibited abnormal internal vascularization and was covered with a capsule formed from growing capillaries and accumulating collagen fibers, suggesting that it was an EIH. No lingering neurological symptoms were noted upon postoperative follow-up. This type of hematoma expands slowly and is asymptomatic, with reported cases consisting of patients that already have neurological deficits due to progressive hematoma growth. Our report is one of a few to provide a clinical picture of the initial stages that occur prior to hematoma encapsulation.

Abstract
We present a 64-year-old woman who was evaluated after being found unresponsive. Imaging revealed a foramen of Monro cavernoma resulting in hydrocephalus. Supratentorial cavernomas are most frequently found in the cerebral cortex, and although ventricular cavernomas do occur, they are rarely located in the foramen of Monro. Foramen of Monro cavernomas are extremely dangerous, requiring aggressive management when identified.

Abstract
Le siège intraventriculaire est une localisation rare des cavernomes de l'encéphale. Le quatrième ventricule est le moins concerné de toutes les localisations. Nous rapportons le cas d'une patiente âgée de 52 ans qui présente depuis 12 mois un syndrome d'hypertension intracrânienne et trouble de l’équilibre. Elle s'est présentée aux urgences avec un GCS à 14, nuque subraide, un syndrome cérébelleux statokinétique avec une acuité visuelle basse et un oedeme papillaire bilatéral. Une TDM cérébrale réalisée aux urgences a objectivé un hématome du 4ème ventricule avec hydrocéphalie active triventriculaire. Une dérivation ventriculaire interne a été réalisée en urgence avec une bonne évolution clinique post opératoire. Le bilan a été complété par une IRM cérébrale objectivant un processus du quatrième ventricule évoquant un cavernome. Un abord direct a été réalisé permettant une exérèse totale du cavernome siégeant au sein du quatrième ventricule. L'anatomo-pathologie a confirmée le diagnostic. A notre connaissance, il s'agit du 13ème cas rapporté dans la littérature. Les cavernomes intraventriculaires représentent 2,5-10% de tous les cavernomes dont 9% est au niveau 4ème ventricule. Les patients sont souvent admis aux urgences suite au saignement de cette malformation angiomateuse. Le diagnostic est rendu accessible par les différentes séquences de l'IRM. Le traitement est souvent chirurgical vu le risque de resaignement. Le pronostic dépend de l’état initial du patient et de l'infiltration du plancher du quatrième ventricule.

Abstract
Background Although cavernous hemangiomas (CHs) can be found anywhere in the central nervous system, CHs of the third ventricle have been reported in only 29 patients (including our case). In the current case report, we discuss the clinical characteristics and surgical outcome of CHs of the third ventricle. Case presentation A 64-year-old female was admitted to our emergency room with a sudden decreased level of consciousness. Brain imaging studies demonstrated a multi-lobulated hemorrhagic mass in the third ventricle. The lesion was removed via the transcallosal-interforniceal approach and pathologically diagnosed as CH. Postoperatively, the patient had a transient neurological deficit due to hypothalamic injury and recovered to the normal status at 2 months after the operation. In the review of 29 cases, the mean age of the patients was 40 years with a slight female preponderance (female/male, 17/12). The majority of the patients complained of a mass effect with signs of increased intracranial pressure; only one case was asymptomatic. Gross total resection was achieved in 81% of the cases. Around 80% of the patients were asymptomatic or improved from the initial symptoms. Mortality rate was 6.9% and the most common complication was hydrocephalus. Conclusions As demonstrated in the review of the previous reports, the outcome is favorable after surgical excision for CH of the third ventricle. Hence, surgical excision appears to be the treatment of choice for CH located in the third ventricle, which tends to grow rapidly resulting in a mass effect.

Abstract
Background: Cerebral cavernous malformations (CCMs) are angiographically occult vascular malformations of the central nervous system. As a result of hemorrhage and mass effect, patients may present with focal neurologic deficits, seizures, and other symptoms necessitating treatment. Once symptomatic, most often from hemorrhage, CCMs are treated with microsurgical resection. Orbital cavernous hemangiomas (OCHs) are similar but distinct vascular malformations that present within the orbital cavity. Even though CCMs and OCHs are both marked by dilated endothelial-lined vascular channels, they are infrequently seen in the same patient. Case Description: We provide a brief overview of the two related pathologies in the context of a patient presenting to our care with concomitant lesions, which were both resected in full without complication. Conclusion: This is the first known report that describes a case of concomitant CCM and OCH and explores the origins of two pathologies that are rarely encountered together in neurosurgical practice. Recognition of disparate symptomatologies is important for properly managing these patients.

Abstract
Object
The threat of symptomatic hemorrhage from cerebral cavernous malformations (CCMs) during pregnancy remains poorly understood. The authors undertook this study to better define the risk of pregnancy-related hemorrhage in this population.
Methods
The records of female patients with sporadic (isolated lesions and negative family history) and familial forms of CCM, which were collected as part of the Barrow Neurological Institute CCM natural history study, were examined. Clinical data related to pregnancy, including type of delivery (vaginal or cesarean section) and any change in neurological status, were obtained from chart reviews and patient interviews.
Results
There were 168 pregnancies among 64 female patients with CCM (28 sporadic and 36 familial). Assuming an average of 46 weeks per pregnancy (40 weeks of gestation and 6 weeks of puerperium), patients were at risk for hemorrhage for a total of 148.6 years. Symptomatic hemorrhage (defined as new-onset or exacerbation of seizure activity or any change in neurological status) occurred during 5 pregnancies, with the most common symptom being seizures (4 cases). The overall risk for symptomatic hemorrhage was 3% per pregnancy; the risk was 1.8% per pregnancy in the sporadic group and 3.6% per pregnancy in the familial patients.
There were 19 deliveries by cesarean section: 5 for obstetrical reasons, 8 for fear of possible hemorrhage, and 6 for unknown reasons. Vaginal delivery was performed without complications for the remaining 149 pregnancies.
Conclusions
The authors' experience suggests that the risk of symptomatic hemorrhage from a CCM during pregnancy is not increased and that a history of CCM is not a contraindication to pregnancy or vaginal delivery.

Abstract
We reported a case of trigonal cavernous malformation (CM) with intraventricular hemorrhage. This 67-year-old woman experienced sudden onset of loss of consciousness and her Glasgow Coma Scale (GCS) was 5 points (E1V1M3) on admission. CT scan demonstrated intraventricular hemorrhage and acute hydrocephalus. Angiography did not demonstrate any vascular abnormality. Ventricular drainage was performed for acute hydrocephalus and the postoperative course was good. CT showed a hyperdense lesion in the left trigone, which was contrast-enhanced on T1-weighted MR. Removal of CM was performed via the left middle temporal sulcus. We conducted a Pub Med search for trigonal CM and found 17 cases. Herein we discuss the symptoms, CT and MR findings and treatment.

Abstract
There is an increased risk of strokes in pregnancy and puerperium. Intracranial haemorrhage is the rarer of the two stroke subtypes but carries a greater morbidity and mortality for both the mother and the child. This review highlights the causes of pregnancy-related intracranial haemorrhage and its management. The incidence varies from region to region with the highest being reported from China and Taiwan. Majority of these haemorrhages are secondary to hypertensive disorders of pregnancy with smaller proportions related to aneurysm and arteriovenous malformation rupture. A small but important contributor is cortical venous thrombosis which, although predominantly gives rise to ischaemic lesions, may lead to parenchymal haemorrhages as well. Presentation is usually with headaches or seizures, with or without focal deficits. Diagnosis requires brain imaging with computerized tomography or magnetic resonance imaging, and the necessity of investigation when this diagnosis is suspected supersedes the small risk of fetal malformation. Management follows the general management principles for intracranial haemorrhage management. Blood pressures need to be strictly monitored and medicines used for controlling them may differ slightly due to teratogenic effects. For preeclampsia, early but safe delivery is the best treatment. For cortical venous thrombosis, low-molecular-weight heparin is the preferred agent. Aneurysms and vascular malformations need to be definitively treated to prevent re-bleed and this can be achieved through surgical or endovascular procedures. The timing of surgery depends on neurosurgical considerations. However, the timing and mode of delivery are governed by obstetric factors. Risk of future haemorrhage depends on whether the underlying aetiology can be and has been definitively treated.

Abstract
The management of brain and spinal cavernomas includes two main options: (i) conservative treatment or (ii) surgical removal. Clinical experience related to cavernoma patients falls into four major categories: the surgical or conservative treatment of incidental or symptomatic cavernomas. In many patients, cavernomas exist as fairly benign lesions, frequently remaining clinically silent for life. This observation argues against the active treatment of all cavernoma patients; rather for the meticulous selection of only those more likely to benefit from surgery. Thus, the most crucial task in successful management of cavernomas is appropriate patient selection. In this review, we present our institutional experience on cavernoma management supplemented with data from the literature.

Abstract
PURPOSE The aim of this study is to assess the efficacy and safety of surgical treatment of orbital cavernomas in terms of clinical and functional results. METHODS Twenty consecutive patients underwent surgical removal of a unilateral orbital cavernoma between 1999 and 2009. Indications for surgical treatment were: visual impairment, diplopia due to ocular movement impairment, progressive and disfiguring unilateral proptosis, severe retroorbital pain clearly related to the orbital cavernoma. We used a topographic classification of the lesions within the orbit. The orbit has been divided into an anterior and a posterior compartment on the axial plane and into three sectors on the coronal plane. The proptosis was quantified on MRI scans. RESULTS The location of the cavernoma determined the choice of the surgical approach. We performed eight lateral orbitotomies and 12 fronto-orbito-zygomatic approaches. All the tumors were completely removed as assessed at follow-up MRI. We did not record any intraoperative or major postoperative complication requiring a reoperation. The postoperative visual acuity improved in four of five patients with visual impairment, it worsened in the other case. Proptosis improved in all the patients. Diplopia improved in four patients, and did not recover in another case. CONCLUSION Surgical treatment of symptomatic orbital cavernomas is safe and effective. Tumor location dictates the choice of surgical approach. Visual function and cosmetic result are the main parameters to evaluate the clinical outcome. Surgical approach and dissection technique are crucial in determining the visual outcome.

Abstract
Object
Intraventricular cavernomas (IVCs) occur in only 2–10% of patients with cerebral cavernomas. Reports concerning IVC are scarce and are limited mostly to sporadic case reports. In this paper, the authors present a series of 12 patients with IVCs that were treated at a single neurosurgical department. In addition, the authors reviewed the literature.
Methods
All clinical data were analyzed retrospectively. Follow-up questionnaires were sent to all patients. Outcome was assessed using the Glasgow Outcome Scale. The authors also conducted a PubMed search and found 77 cases of IVC.
Results
The patients' median age was 47 years, and the male/female ratio was 2:1. A cavernoma occurred in the lateral ventricle in 6 patients, in another 5 it was in the fourth ventricle, and 1 had a lesion in the third ventricle. Almost all patients presented with acute headache on admission and in more than half, the symptoms were related to cavernoma bleeding. In total, 8 rebleedings occurred in 5 patients during a median of 0.4 years. Three patients with a cavernoma of the fourth ventricle presented with a cranial nerve deficit. In 8 cases, a cavernoma was surgically treated an average of 1.3 years after the diagnosis. Only 1 patient underwent surgery in the acute phase after a major intraventricular/intracerebral hemorrhage. The median follow-up time was 2 years. No patient was lost to follow-up, and no patient died. In total, on follow-up 9 patients improved and 3 had a persistent neurological deficit, of which 2 existed before surgery.
Conclusions
In the present series, the IVCs had a high tendency for rehemorrhage. Surgery is advocated when hemorrhages are frequent, and the mass effect causes progressive neurological deficits. Microsurgical removal of the IVC is safe, but in the fourth ventricle it can carry increased risk for cranial nerve deficits.

Abstract
PURPOSE Intraventricular cavernomas are rare. Even more rare are those presenting in the trigone of the lateral ventricles. METHODS We performed a search of the literature of the last 30 years and identified all cases of intraventricular cavernous angiomas. Trigonal cavernomas were separately identified and analysed. Our search yielded a total of 13 trigonal cavernomas. RESULTS Of a total of 61 intraventricular cases, 13 were located in the trigone of the lateral ventricles. The most prominent presenting symptom was intracranial hypertension (68.9%), followed by seizures (18.2%) and hemorrhage (13.1%).The literature review revealed a trend of intraventricular cavernomas to present with intracranial hypertension rather than seizures or focal neurologic deficit, unlike their intraparenchymal counterparts. We feel that this difference has received little attention in the international literature. We discuss a possible pathogenetic mechanism for the presence of intracranial hypertension and address different aspects of diagnosis and treatment of this benign lesion. CONCLUSIONS Trigonal cavernomas are benign lesions that have an excellent outcome after radical excision. Symptoms and signs of intracranial hypertension and hydrocephalus may be the prominent initial presentation of this rare ailment.

Abstract
Introduction Cavernous hemangiomas of the orbit are benign vascular malformations, commonly encountered in adults. Although they are infrequent in pediatric population their diagnosis and course are of a great significance, mainly because they can cause visual disturbances such as amblyopia that can ensue, and secondarily due to their cosmetic and psychological effect. Special attention is required in follow up and treatment. Additionally, a systemic evaluation is necessary in order to discover asymptomatic lesions elsewhere in the body carrying a risk of complications. Case presentation The authors describe the clinical course, diagnosis, therapeutic approach and prognosis of an infant with an orbital cavernous hemangioma accompanying intracranial lesions. A female infant 18 months of age, presented with a mass in the left upper eyelid, causing blepharoptosis. Preoperative magnetic resonance imaging and angiography of the brain and the orbits showed a hemangioma of the left upper eyelid and intracranial lesions to the left temporal fossa and the pons. At the age of 2 years and 8 months she was admitted again due to severe eyelid swelling, intense strong pain, exophthalmos and collateral ophthalmoplegia. Two operations were performed to remove the orbit mass. Histological examination, showed characteristics of cavernous hemangioma. Conclusion The atypical presentation of cavernous orbital hemangioma with early infantile onset, merits attention.

Abstract
ABSTRACT
CAVERNOUS MALFORMATIONS OF the basal ganglia and thalamus present a unique therapeutic challenge to the neurosurgeon given their unclear natural history, the risk of surgical treatment, and the unproven efficacy of radiosurgical therapy. Via a PubMed search of the English and French literature, we have systematically reviewed the natural history and surgical and radiosurgical management of these lesions reported through April 2008. Including rates cited for “deep” cavernous malformations, annual bleeding rates for these lesions varied from 2.8% to 4.1% in the natural history studies. Across surgical series providing postoperative or long-term outcome data on 103 patients, we found an 89% resection rate, a 10% risk of long-term surgical morbidity, and a 1.9% risk of surgical mortality. The decrease in hemorrhage risk reported 2 years after radiosurgery might be a result of natural hemorrhage clustering, underscoring the unproven efficacy of this therapeutic modality. Given the compounded risks of radiation-induced injury and post-radiosurgical rebleeding, radiosurgery at modest dosimetry (12–14 Gy marginal doses) is only an option for patients with surgically inaccessible, aggressive lesions.

Abstract
BACKGROUND Cavernous angiomas are vascular malformations which rarely involve the cavities of the lateral ventricles. Knowledge of the specific clinical and neuroradiological features displayed by these lesions is limited by the scarcity of patients included in the reported series. OBJECTIVE AND METHODS The aim of this study was to compile and analyse the epidemiological, clinical, neuroradiological and surgical characteristics of these lesions as provided by the well-described examples reported in the scientific literature. A total of 49 were gathered, including three patients operated on recently in our Department. FINDINGS AND CONCLUSIONS Cavernomas developing within the ventricular cavities attain a larger size than parenchymal counterpart lesions, causing symptoms and signs derived mainly from the mass effect. The characteristic parenchymal hypointense rim is less frequently identified on T2-weighted echo-gradient MRI sequences. Total surgical excision is the treatment of choice for these lesions, yet the surgical routes employed may still be associated with a high rate of neurological complications.

Abstract
Orbital cavernous hemangiomas (CHs) manifest as slowly developing symptoms indicative of slow growth. The present study investigated the involvement of angiogenic factors and their receptors in the growth of orbital CHs. Surgical specimens of orbital CHs were obtained from nine patients. Formalin-fixed, paraffin-embedded specimens were stained immunohistochemically using antibodies against Ki-67, CD31, alpha-smooth muscle actin (alpha-SMA), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and VEGF receptors (flt-1 and flk-1). CD31 was expressed in the single layer of endothelial cells lining the vascular cavity. The thick vascular walls were positive for alpha-SMA, indicating that the vascular walls were smooth muscle cells. Ki-67 antigen immunostaining was mostly positive in the vascular walls and the staining index ranged from 0% to 6.8% (mean +/- standard deviation, 2.7 +/- 1.9%). VEGF and bFGF immunostaining were positive in all specimens. Flt-1 immunostaining was negative in all specimens, but flk-1 immunostaining was positive in both endothelial cells and smooth muscle cells. These results suggest that both VEGF and its receptor flk-1 are important in the growth of orbital CH.

Abstract
There is growing evidence to suggest that pregnancy may increase the risk of hemorrhage from cavernous malformations (CMs). In the present case, a 21-year-old primigravida was admitted to the authors' neurosurgical service after a cesarean section. Three weeks before admission she had experienced rapidly progressive bilateral lower-extremity paresthesias. Spinal magnetic resonance (MR) imaging revealed the presence of an intramedullary thoracic lesion. On T2-weighted MR images, heterogeneous signal intensity with a rim of decreased intensity was demonstrated in the spine. The mass was successfully resected, and 1 year later the patient's symptoms had resolved completely. This is the fourth reported case of a spinal intramedullary CM that became symptomatic during pregnancy. The pathogenesis and management of this entity are reviewed.

Abstract
BACKGROUND Intraventricular cavernous angiomas are very rare. Only few cases of trigonal angiomas have been reported. CASE DESCRIPTION We report three cases of trigonal cavernous angiomas who presented with raised intracranial pressure or seizures and who underwent total excision with a good recovery. We also review the literature and discuss surgical approaches. CONCLUSION On magnetic resonance imaging, intraventricular cavernous angiomas lack the hemosiderin ring characteristically seen around parenchymal cavernous angiomas. This explains why trigonal cavernous angiomas can mimic malignant neoplasm on imaging, and they should be considered in the differential diagnosis of intraventricular masses. Total excision should be the goal of surgery.

Abstract
BACKGROUND Cavernomas are an uncommon lesion seen in neurosurgical practice that can occasionally rupture. Recent developments in neurosurgical technique and microbiology have brought greater insight into the treatment and molecular pathogenesis of cavernoma. In this review, a historical overview of cavernous angioma, a current paradigm for treatment, promising new molecular biological developments, and suggestions for future directions in neurosurgical research are presented, with emphasis on practical clinical applications. METHODS A survey of the literature on cavernous angioma and consultation with the Department of Neurosurgery at Northwestern Memorial Hospital was conducted by the authors to gain greater insight regarding this lesion. Papers and consultation revealed the importance of careful evaluation of this lesion, new techniques such as functional magnetic resonance imaging and frameless stereotaxy that simplify clinical management of cavernomas, and potential mechanisms by which to tackle this lesion in the future. New basic knowledge on disease biology is summarized with practical applications in the clinical arena. RESULTS There appear to be a number of controversies regarding management of this lesion. These include risk factors faced by the patient, controversy over the importance of resection, and modality through which the treatment should occur. An algorithm is presented to aid the neurosurgeon in management of these lesions. CONCLUSIONS Exciting developments in neurosurgery and molecular biology will continue to have a major impact on clinical treatment of this disease. Unresolved issues regarding the importance of certain risk factors, the role for radiotherapy in treatments, and the underlying molecular abnormalities must be tackled to gain greater clarity in treatment of this lesion.

Abstract
CT and MR imaging are particularly important in the diagnostic investigation of patients with vascular disorders of the orbit. The improved image quality of CT and MR imaging, along with dynamic CT angiography, MR angiography, MR venography, and multiphase dynamic contrast CT/MR imaging, has proven useful to delineate as well as differentiate various orbital vascular lesions. This article presents the current classification of orbital vascular disorders and describes the CT/MR imaging characteristics of orbital cavernous hemangiomas and simulating lesions.

Abstract
A 72-year-old female complained of acute pain on left eye movement followed by progressive exophthalmos. Neuroimaging revealed a large well-demarcated lesion consisting of solid and cystic parts, as well as bone destruction and hemorrhage, within the left orbital cavity. The preoperative diagnosis was pleomorphic adenoma with or without malignant transformation, or cavernous angioma. En bloc excision including adjacent tissues was planned to resolve the progressive symptoms and to obtain a histological diagnosis. The transcranial route was chosen since tumor invasion to the cranial base was possible. The histological diagnosis was pleomorphic adenoma. Pathological and preoperative radiological examinations indicated that repeated intratumoral hemorrhage had caused the orbital bone destruction and acute orbital pain. Neoplasms should be differentiated from a wide spectrum of other possible pathologies. Accurate clinical diagnosis of neoplasm in the orbital cavity is important for correct therapeutic management. Malignancy is generally suspected if painful and progressive signs and symptoms are associated with an orbital mass lesion. The present case suggests that pleomorphic adenoma should also be considered in the differential diagnosis. The therapeutic strategy for lacrimal gland tumors remains controversial, so a flexible management approach is required.

Abstract
Object. The authors reviewed angiograms obtained in patients with cavernous malformations to identify and characterize coexisting venous drainage.
Methods. Fifty-seven patients with cavernous malformations treated at the authors' institutions between 1994 and 2002 were classified into three groups according to the venous system adjacent to the malformation on angiography studies. In Group A patients (23 patients) the malformations had no venous drainage; in Group B patients (14 patients) the lesions were associated with typical venous malformations; and in Group C patients (20 patients) the lesions had atypical venous drainage (AVD). The risk of hemorrhage based on the type of associated venous drainage was analyzed, and the usefulness of magnetic resonance (MR) imaging compared with digital subtraction (DS) angiography in demonstrating associated AVD was determined.
Fifty-seven patients harbored 67 cavernous malformations: Group A patients had 29 cavernous malformations with no associated venous drainage; Group B patients had 17 lesions associated with venous malformations; and Group C patients harbored 21 lesions, 20 of which manifested AVD. Symptomatic hemorrhage was present in 10 (43.5%) of 23 Group A patients and in 28 (82.4%) of 34 Groups B and C patients. Although high-resolution MR imaging revealed the presence of associated venous malformations in 11 (78.6%) of 14 Group B patients, such studies demonstrated AVD in only two (10%) of 20 Group C patients.
Conclusions. Patients harboring cavernous malformations plus venous malformations or AVD are more likely to present with symptomatic hemorrhage than are patients with cavernous malformation alone. The actual incidence of associated venous drainage may be underestimated when MR imaging alone is used rather than combined with DS angiography.

Abstract
The better understanding of the natural history of the cavernous malformations and the improvement of diagnostic methods and of microsurgical techniques have made the management of cavernous malformations possible through the conservative treatment, radiosurgery, and microsurgical resection. We present 33 cases operated at our service at Santa Casa Hospital, Belo Horizonte, from 1992 to 2001. Cortical and subcortical cavernomas manifested by epilepsy (57.5%) or mainly by hemorrhage (15.1%) were surgically approached. The deep lesions (basal ganglia, thalamus and brain steam) represented 27.7% of our cases. They should only be operated when located near the pial or ependimary surface. The resection of spinal cord lesions (5.5%) and of deep brain lesions is also recommended when they present progressive focal deficit (13.8%) or recurrent episodes of hemorrhage (13.8%). Small and deep seated cavernomas that do not present bleeding must be conservatively treated. There has been no evident favourable result related to radiosurgery so far.

Abstract
✓ Extraaxial cavernous hemangiomas are rare intracranial lesions that can be located in different cranial compartments. Extension across different tissue planes such as the subcutaneous tissue, skull, orbital cavity, intracranial dura mater, and extracranial trigeminal divisions within the same patient has not been previously reported.
This 32-year-old woman suffered left exophthalmos, left sixth nerve palsy, and trigeminal neuropathy. Magnetic resonance imaging studies revealed an extensive multicompartmental lesion, with enhancement following Gd administration.
A left orbitopterional approach allowed removal of several cavernomatous lesions located in the orbit, frontotemporal dura, and lateral wall of the cavernous sinus. A histologically based diagnosis of extraaxial cavernous hemangioma was made. In the postoperative period the patient experienced a regression of her symptoms.
The authors report on a case of cavernous hemangioma with a unique extension to different intracranial/extracranial compartments. Although radical removal of the lesion was not feasible, partial excision allowed for satisfactory clinical control of the patient's symptoms.

Abstract
PURPOSE To evaluate the long-term prognosis of visual function in patients with orbital cavernomas after conservative and surgical treatment. DESIGN Interventional case series. METHODS The authors describe the outcome of 20 patients with cavernous hemangiomas of the orbit treated in their departments between 1988 and 2003. This prospective study included five cases followed by clinical and radiologic observation and 15 cases of symptomatic tumors that were completely removed by means of a frontotemporal or by means of a transconjunctival approach. The clinical characteristics of orbital cavernomas were analyzed together with their appropriate treatment. Furthermore, the authors present the unusual case of a patient suffering from progressive visual deterioration from a cerebral cavernoma compressing the optic nerve. RESULTS The follow-up period was between 3 and 10 years. All orbital cavernomas in the group of conservatively managed patients remained stable. The transconjunctival excision of a medially located lesion was uncomplicated. The frontotemporal approach was chosen for large tumors situated in the proximity of the orbital apex and was associated with a higher number of complications. A good overall outcome of visual function and patient satisfaction was achieved in 11 of 14 cases operated on by craniotomy. CONCLUSION The combination of clinical signs and magnetic resonance imaging (MRI) is highly sensitive and specific for the diagnosis of orbital cavernomas. In the presence of visual deterioration clearly attributable to the tumor we recommend immediate surgery, while lesions producing solely exophthalmos can safely be followed by observation. The transcranial approach offers excellent exposure and a rewarding cosmetic result and may be considered for large lesions superior and medial to the optic nerve, especially if they involve the orbital apex.

Abstract
A 16-year-old girl presented with multiple cerebral cavernous angiomas with calcifications due to repeated hemorrhages and a thrombosed cerebral arteriovenous malformation (AVM). Her 18-year-old elder sister also had multiple cerebral cavernous angiomas associated with calcifications, which suggested presence of repeated previous hemorrhages. Surgical removal via a right occipital craniotomy resulted in a good outcome. The histological diagnosis was thrombosed AVM. Evaluation of congenital vascular anomaly needs to take into consideration the combination of other congenital vascular anomalies and their familial occurrence.

Abstract
Cavernomas are well circumscribed lesions formed by sinusoidal vascular channels. They tend to slowly expand in size and carry a 0.7% to 1.1% annual risk of hemorrhage. Only 10% to 30% of intracranial cavernomas are located in the posterior fossa. When located in the brainstem they can cause recurrent hemorrhages and devastating neurological deficits. The authors report a series of cavernomas located in the brainstem and present a review on their epidemiology, pathogenesis, natural history, and methods of diagnosis and treatment. Although the surgical treatment of brainstem cavernomas can be associated with a significant risk, surgical resection is recommended of the lesions that have hemorrhaged or grown producing progressive deficits. The authors' experience on the surgical treatment of cavernous hemangiomas of the brainstem, indicating important aspects of intra-operative surgical techniques, is presented, including a clinical and anatomical correlation of different surgical approaches to brainstem cavernomas.

Abstract
We present a surgical series of 35 patients (25 males and 10 females) with histopathologically verified intracranial cavernous angiomas. The 35 malformations were located as follows: 21 were in the cerebral hemispheres; 4 in the lateral ventricles, 4 in the brain stem; and 6 in the cerebellum. Seizures and focal neurological deficits were the main clinical features observed in patients with intracranial cavernous angiomas. A number of these vascular malformations were misdiagnosed by computerized tomography. In the last 10 years, magnetic resonance imaging has been the most sensitive method for detecting these lesions. Thirty-five cavernous angiomas were treated surgically; in 33 patients a complete excision, and in 2 patients subtotal excision were obtained. One of the patients died one year after the operation. The overall outcome was good in all of the 34 remaining patients, resulting in improved seizure control or neurological deficit. The rationale for neurologic differential diagnosis and surgical treatment and follow up results are discussed.

Abstract
UNLABELLED Cavernous malformations are uncommon lesions that are usually present in the cerebral hemispheres. They occur rarely in the ventricular system, and even more rarely in the lateral ventricle. Only 28 cases have been previously reported in the literature. CASE We present one case of lateral ventricle cavernoma in a 15-years-old female patient, who suffered of mild chronic headache for 8 months, followed by two episodes of sudden intensive headache and stupor with complete recovery after 48 hours. CT scan was performed and revealed a voluminous size, hiperdense mass in the frontal horn of the lateral ventricle. The surgical access to site was through transcallosal interhemisphere approach. The patient had a good recovery without complications. CONCLUSION Although lateral ventricle cavernomas are rare they should be considered in the differential diagnosis of intraventricular tumors. A wrong preoperative diagnosis has sometimes induced a wrong therapy, such as radiotherapy, for these surgically curable benign lesions.

Abstract
A rare case of persistent intractable hiccup as presenting symptom of cavernous angioma in the medulla oblongata is reported. Pathophysiologic hypotheses about the triggering mechanism of hiccup are discussed, with special reference to the causes affecting the central nervous system. A review of the literature concerning medullary lesions presenting with persistent hiccup is also reported. Finally we have included some brief considerations about cavernous angiomas and the patterns of their clinical presentation, focusing on those located in the medulla oblongata.

Abstract
OBJECTIVE Cavernous hemangiomas located within the cavernous sinus are rare vascular tumors that are very difficult to remove because of severe intraoperative bleeding. The purpose of this study was to analyze the clinical, neuroimaging, and pathological features and the surgical treatment of these tumors. METHODS Ten patients with cavernous hemangiomas in the cavernous sinus who were surgically treated from August 1985 to October 1997, in our hospital, were retrospectively studied. RESULTS Among the 10 patients, total tumor removal was performed in four cases, partial removal in two cases, and tumor biopsies in four cases. The four patients who underwent total tumor removal experienced uneventful postoperative courses, with no postoperative neurological deficits for one patient, no new neurological deficits for two patients, and complete ophthalmoplegia and diminished sensation in the distribution of Cranial Nerve V1 for one patient. The two patients who underwent partial removal developed complete ophthalmoplegia and diminished sensation in the distribution of Cranial Nerve V1 after surgery, and one of them experienced contralateral paralysis. All four patients who underwent tumor biopsies experienced severe intraoperative tumor bleeding; one exhibited Cranial Nerve III, IV, and VI injuries after surgery. CONCLUSION The features of prominent hyperintensity in T2-weighted scans, with well-defined borders in enhancing magnetic resonance imaging scans, or marked enhancement in computed tomographic and magnetic resonance imaging scans, with no tumor blush in angiographic analyses, facilitate the diagnosis of these tumors. These tumors can be divided into two subgroups on the basis of intraoperative findings and pathological features. We do not recommend division and piecemeal removal of the tumor during surgery if the main supplies of the tumor have not been interrupted.

Abstract
BACKGROUND We review the surgical anatomy of the brain stem in relation to the surgical approaches adopted for treatment of cavernomas and identify possible "safe entry zones" on the anterior face of the brainstem. METHODS Twelve symptomatic patients with cavernoma or telangectasia of the brain stem were surgically treated. The brain stem was divided into the following anatomical areas: ventral medulla, dorsal medulla, dorsal pons, ventral pons, ventral mesencephalon, and dorsal mesencephalon, so that the surgical approach could be "individualized" according to the position of the cavernoma, the nerve fasciculi and nuclei. RESULTS On the anterior surface of the brain stem a medullar paramedian oblique access to the anterolateral sulcus and a paramedian sagittal pons access seem to avoid the main nerve fasciculi and nuclei. CONCLUSIONS Although the parenchymal window produced by the cavernoma is the most important parameter for the choice of approach, fairly safe entry zones may be identified even on the anterior surface of the medulla and pons.
