BACKGROUND: The natural history of cavernous malformations (CMs) has remained unclear. This lack of knowledge has made treatment decisions difficult. Indeed, the use of stereotactic radiosurgery is nowadays controversial. The purpose of this paper is to throw light on the effectiveness of Gamma Knife radiosurgery (GKRS) therapy. METHODS: The authors reviewed data collected from a prospectively maintained database. A total of 95 patients (57 female and 38 male) underwent GKRS for high-surgical-risk CMs...

Cavernous Hemangiomas (CH) arise from any part of the cerebrum. Intraventricular lesions are rare and pure third ventricular localization is rare for CHs. Cavernomas of the ventricles may present with bleeding or signs associated with hydrocephalus. Radical excision is advocated for optimal management of cavernomas. In the present study, we present two cavernomas of the third ventricle which were completely excised via interhemispheric transcallosal transforaminal and Sylvian approaches. Radical excision should be the aim of the surgeon since reoperation for residual cavernomas is more commonly associated with complications and poor outcome...

BACKGROUND AND PURPOSE: Studies in animal models suggest that inflammation is a major contributor to secondary injury after intracerebral hemorrhage (ICH). Direct, noninvasive monitoring of inflammation in the human brain after ICH will facilitate early-phase development of anti-inflammatory treatments. We sought to investigate the feasibility of multimodality brain imaging in subacute ICH. METHODS: Acute ICH patients were recruited to undergo multiparametric MRI (including dynamic contrast-enhanced measurement of blood-brain barrier transfer constant (K(trans) ) and PET with [(11) C]-(R)-PK11195)...

OBJECTIVE: Since 2008, the modified Rex shunt has been used for the treatment of extrahepatic portal venous obstruction (EHPVO) in our center, and satisfactory results were initially achieved. However, the postoperative recurrence rate gradually increased. We therefore performed a retrospective study to evaluate the outcome and identify the optimal procedure. METHODS: Between October 2008 and March 2016, 79 children with EHPVO underwent the Rex shunt in our hospital: 48 underwent the gastroportal shunt (GP), 26 underwent the portal cavernoma-Rex shunt with interposition of grafted portal vessel (PP), and 5 underwent a spleen-preserving splenoportal bypass (SP)...

BACKGROUND: The mesial temporal region (MTR) is located deep in the temporal lobe and it is surrounded by important vascular and nervous structures that should be preserved during surgery. OBJECTIVE: To describe microsurgical anatomy and approaches to the MTR in relation to cavernomas and arteriovenous malformations (AVMs). METHODS: Five formalin-fixed and red silicone-embedded heads of adult cadavers were used for this study. Between January 2003 and June 2014, 7 patients with cavernomas and 6 patients with AVMs in the MTR underwent surgery...

BACKGROUND: Although anterior temporal lobectomy may be a definitive surgical treatment for epileptic patients with mesial temporal sclerosis, it often results in verbal, visual, and cognitive dysfunction. Studies have consistently reported the advantages of selective procedures compared with a standard anterior temporal lobectomy, mainly in terms of neuropsychological outcomes. OBJECTIVE: To describe a new technique to perform a selective amygdalohippocampectomy (SAH) through a transpalpebral approach with endoscopic assistance...

CONTEXT: Restless legs syndrome (RLS) is a common neurological disorder characterized by an irresistible urge to move the lower limbs often accompanied by unpleasant sensations in the legs, worsened at rest and in the evening. Symptoms are improved by movement. Its pathophysiology remains poorly understood. Lesion-related RLS has been reported, mainly in cases of stroke-related RLS involving the brainstem and lenticulostriate nuclei. Only few data of RLS in a context of spinal cord injury have been reported...

Intramedullary cavernomas are rare lesions constituting 5 to 12% of all intramedullary tumours. They are more recognized after introduction of magnetic resonance imaging and detection rates have improved by advance techniques. They may be solitary or multiple or may have associated cranial lesions. They may present with gradual neurological decline or with acute loss of spinal function. In addition neurological deficit depends on the location of the lesion within the spinal cord. We are reporting the case of a 45 year old male who presented with neck pain and progressive right arm weakness with numbness...

Hemangiomas of the median nerve are extremely rare; only 12 cases have been reported in the literature. We discuss a patient who presented with paresthesia and pain along the distribution of the left median nerve secondary to a cavernoma of the proximal part of the nerve as suspected on MRI scan. Total removal of the mass was achieved with immediate relief of the symptoms and no neurologic deficit. We conclude that despite being quite rare, the diagnosis of occult vascular lesions of peripheral nerves such as the median nerve, should be considered, especially when other common pathologies are excluded...

PURPOSE: The prevalence of cavernomas (cavernous hemangioma) is 0.1-0.7%. Cavernomas are often found as an incidental finding within the framework of magnetic resonance imaging (MRI) examinations in mainly young and healthy patients. In the literature, the reported risk of hemorrhage varies greatly and is sometimes higher than that of aneurysms, which is surprising given that cavernomas are part of the low blood pressure system. After the diagnosis the medical practitioner and the patient have to decide on the further therapy, either surgical removal or the strategy of watchful waiting (conservative treatment)...

Maternal brain death during pregnancy remains an exceedingly complex situation that requires not only a well-considered medical management plan, but also careful decision-making in a legally and ethically delicate situation. Management of brain dead pregnant patients needs to adhere to special strategies that support the mother in a way that she can deliver a viable and healthy child. Brain death in pregnant women is very rare, with only a few published cases. We present a case of a pregnant woman with previously diagnosed multiple brain cavernomas that led to intracranial hemorrhage and brain stem death during the 21st week of pregnancy...

REVIEW
Caroline Tilikete, Virginie Desestret
Hypertrophic degeneration of the inferior olive is mainly observed in patients developing palatal tremor (PT) or oculopalatal tremor (OPT). This syndrome manifests as a synchronous tremor of the palate (PT) and/or eyes (OPT) that may also involve other muscles from the branchial arches. It is associated with hypertrophic inferior olivary degeneration that is characterized by enlarged and vacuolated neurons, increased number and size of astrocytes, severe fibrillary gliosis, and demyelination. It appears on MRI as an increased T2/FLAIR signal intensity and enlargement of the inferior olive...

A 59-year-old woman with a remote history of invasive ductal carcinoma of the breast was found on a follow-up computed tomography scan of her brain to have a 1-cm lesion in the right frontal lobe in 2008. In the ensuing years, before her current admission, multiple imaging studies of the brain revealed that the lesion was stable and it was, therefore, interpreted as a small area of encephalomalacia related to a thrombosed cortical vein, a cavernoma, or treated metastatic breast cancer. In 2013, the patient underwent a bilateral salpingo-oophorectomy for ovarian tumors that were diagnosed as bilateral serous cystadenofibromas...

AIM: Extrahepatic portal vein obstruction (EHPVO) is characterized by features of recent thrombosis or portal hypertension with portal cavernoma as a sequel of portal vein obstruction. Imaging of spleno-portal axis is the mainstay for the diagnosis of EHPVO. The aim of this study is to analyze the role of imaging in the preoperative assessment of the portal venous system in children with EHPVO. MATERIALS AND METHODS: A hospital-based cross-sectional study was conducted on twenty children with EHPVO aged between 1 and 18 years over a period of 1 year...
