Benign solid liver tumors are a heterogeneous group of lesions (adenoma, focal nodular hyperplasia, hemangioma, etc.) with highly varied epidemiological characteristics. Advances in diagnostic methods have improved preoperative diagnosis. Magnetic resonance imaging has become the key test, but there is still a percentage of cases in which definitive preoperative diagnosis ...

Benign hepatic tumors include a broad spectrum of regenerative and true neoplastic processes. Because of advances in imaging studies such as computed tomography (CT) and magnetic resonance imaging (MRI) as well as progress in immunohistochemistry, accurate diagnosis can now be made in a large percentage of patients without surgical laparotomy ...
Quiñones-Hinojosa Alfredo - - 2005
OBJECTIVE AND IMPORTANCE: Brainstem cavernous malformations that seem to come to a pial or ependymal surface on preoperative magnetic resonance imaging studies may, in fact, be covered by an intact layer of neural tissue. For cavernous malformations in the cerebral peduncle, intraoperative stimulation mapping with a miniaturized probe can determine ...

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 ...

Neurophysiological monitoring during surgery to avoid damaging of eloquent brain areas is a useful tool. We are performing intraoperative neurophysiological test to locate motor, sensitive and speech areas with cortical stimulation and cranial nerves during cerebellopontine cranial base surgery. Neurophysiological monitoring during brain stem surgery has been less described. Brain ...

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 ...

Koulouris George - - 2005
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 ...
Yasui Toshihiro - - 2005
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 ...
Iakovlev G - - 2005
PURPOSE: To review, from a retrospective series of 48 patients presenting with seizures associated with one or more supratentorial cavernoma(s), the natural history of the seizures and outcome according to medical and surgical treatment.
