BACKGROUND: Cerebral cavernous malformations (CCMs) are congenital vascular anomalies that can cause seizures, intracranial hemorrhages, focal neurological deficits, and migrainelike headaches. Magnetic resonance (MR) imaging has substantially facilitated diagnosis of CCM. It is now widely accepted that familial clustering with an autosomal dominant inheritance pattern should be suspected in cases ...

Hemorrhage into the structures of the anterior visual pathway, apoplexy of the chiasma or optic nerves, is a rare pathology that can be caused by different pathological processes among which cavernous angioma and arteriovenous malformation are more frequently mentioned. The cause of chiasmatic apoplexy may be also hemorrhage into the ...

A case is discussed of a brain abscess complicating an intracerebral haemorrhage occurring in a cavernous haemangioma. A young child presented with focal seizures as a result of a large intracerebral haemorrhage, occurring in a cavernous haemangioma. The only clue to the underlying vascular malformation was the presence of an ...

Patients with germ line mutations in the VHL tumor suppressor gene are predisposed to the development of highly vascularized tumors within multiple tissues. Loss of pVHL results in constitutive activation of the transcription factors HIF-1 and HIF-2, whose relative contributions to the pathogenesis of the VHL phenotype have yet to ...

Current laparoscopic stapling technology still cannot prevent bile leakage (<55%) along the resection margin. A new staple line reinforcement technique was used in the present case. This technique incorporates an absorbable polymer membrane into the stapler system, such that it buttresses the transected solid organ. The objectives of this novel ...

Cowden syndrome (CS) is a rare autosomal dominant genodermatosis, characterized by multiple hamartomas, particularly of the skin, associated with high frequencies of breast, thyroid, and genitourinary malignancies. Although Lhermitte-Duclos disease (LDD) or dysplastic gangliocytoma of the cerebellum, a slowly progressive unilateral tumor, is a major criterion of CS, its frequency ...

AIM: Cavernomas located in eloquent areas of cerebral hemispheres represent a challenge for the neurosurgeon. An accurate surgical approach is essential to completely remove the lesion with function preservation. Aim of this study was to evaluate the usefulness of integration between standard magnetic resonance imaging (MRI) for neuronavigation and functional ...

Though cranial hemangiomas are second only to vertebral hemangiomas in frequency, such lesions are rarely congenital and multiple. It is probable that the true incidence of congenital calvarial hemangiomas is higher than that reported in the literature, as they are unlikely to undergo imaging, most being asymptomatic and without a ...

BACKGROUND AND PURPOSE: Cerebral cavernous malformations (CCMs) are focal dysmorphic blood vessel anomalies that predispose patients to hemorrhagic stroke and epilepsy. CCMs are sporadic or inherited and 3 genes (CCM1, CCM2, and CCM3) have been identified. However, the role of somatic mutation in CCM genesis has been disputed. The hypothesis ...

BACKGROUND: Many reports have demonstrated a worse prognosis for patients whose cavernomas were subtotally removed than for those whose cavernomas were not surgically treated. Therefore, it is better not to touch the cavernoma if a surgeon is not prepared to totally remove it. This report describes a large brainstem cavernoma ...

OBJECTIVE AND IMPORTANCE: Angioleiomyomas (ALMs) are relatively rare, benign, vascular soft tissue tumors that occur most frequently in the extremities of middle-aged individuals. To date, only two cases of intracranial ALMs have been described, both with little emphasis on the clinical, surgical, and radiological aspects. Neither of these reported cases ...

OBJECT: Cerebral cavernous malformations (CCMs) have previously been considered as congenital and biologically static malformations. On the other hand, the potential for growth and de novo generation of CCMs have also been reported. It is therefore important to study the proliferative and neoangiogenetic capacity of these lesions. METHODS: The authors ...

OBJECTIVE: Although craniotomy is the preferred treatment for symptomatic solitary supratentorial cavernous malformation (CM), radiosurgery is also an option. Our aim was to see which of these strategies was the most effective and under what circumstances. METHODS: Of the 46 patients with solitary supratentorial CM that we retrospectively studied, 24 ...

INTRODUCTION: Cavernous hemangioma is increasingly recognized as a late complication of cerebral irradiation (CI); however, the significance of the problem, especially the risk of hemorrhage, is not documented in the literature. In order to discover this, we reviewed our experience of radiation-induced cavernous hemangiomas (RICH) in patients who had received ...

The pathogenesis of cerebrovascular malformations is currently unknown. Lately recent researchs suggest that their pathogenesis and development might be due to a series of factors taking part in angiogenesis. Angiogenic growth factors including vascular endothelial growth factor, proliferating nuclear cell antigen, Ki-67, vascular endothelial growth factor (VEGF), VEGF receptor (VEGFR) ...

Stereotactic radiosurgery is a controversial treatment modality in the management of cerebral cavernous hemangiomas (CHs), and results vary from center to center. Even the interpretation of treatment failure is controversial. It is suggested that the systematic pathological investigation of irradiated specimens could help to resolve the controversy. A hemorrhagic lesion ...
