BACKGROUND: Peri-lesional edema is a serious and well-known complication of stereotactic radiosurgery (SRS). Here we evaluated edema risk after SRS and assessed its formation and resolution dynamics. PATIENTS AND METHODS: 107 patients underwent SRS for heterogeneous diagnoses: 34 (29%) with arteriovenous malformations, 38 (35%) with meningiomas, 16 (15%) with metastatic tumors, 16 (15%) with acoustic neuromas, 3 with (3%) cavernomas, and 2 (2%) each with anaplastic astrocytomas and anaplastic oligoastrocytomas...

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...

BACKGROUND: Epilepsy, a common neurological disorder can present at any age and has a number of aetiologies with underlying brain disease being the most common aetiology. Brain imaging becomes important and mandatory in the work up for epilepsy in localization and lateralization of the seizure focus. METHODS: This cross-sectional study was conducted in the department of Radiology Ayub Medical Teaching Institution Abbottabad from 1st March 2015 to 31st March 2016...

BACKGROUND: Cavernoma of the optic chiasm is a rare disease, and the most common clinical presentation is chiasmal apoplexy. Almost all the cases reported in the literature were treated surgically with craniotomy. CASE DESCRIPTION: We report a case of optochiasmatic cavernoma successfully resected via an endoscopic endonasal transsphenoidal approach (EETA). CONCLUSIONS: Rapid diagnosis and complete resection of a symptomatic optochiasmatic cavernoma are helpful in improving visual dysfunction...

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...

INTRODUCTION: Medulloblastoma is the most frequent malignant brain tumour in children. Radiation-induced cavernous haemangiomas (RICHs) are a known late complication of radiation exposure, especially in young children. CASE REPORT: We present a patient who underwent subtotal resection of posterior fossa medulloblastoma with subsequent chemotherapy and radiotherapy at the age of 10 years. A new lesion in the region of the left foramen of Monro appeared 16 years later...

AIM: To evaluate the value of radiosurgery with a rotating gamma-system (RGS) for cerebral cavernomas. PATIENTS AND METHODS: Seventy-nine patients with symptomatic cerebral cavernomas underwent RGS radiosurgery at the Bach Mai Hospital, Hanoi, Vietnam. Median dose (single fraction) was 20 Gy (range=14-26 Gy). Endpoints included effect on headache, seizures and tumor size. RESULTS: Of 60 patients with headache, 17% had complete response, 82% partial response and 2% stable disease (best response)...

PURPOSE: Developmental venous anomalies (DVA) are common neuroimaging abnormalities that are traditionally diagnosed by contrast-enhanced T1-weighted images as the gold standard. We aimed to evaluate the sensitivity of SWI in detecting DVA and associated cavernous malformations (CM) and microhemorrhages in children in order to determine if SWI may replace contrast-enhanced MRI sequences. METHODS: Contrast-enhanced T1-weighted images were used as diagnostic gold standard for DVA...

BACKGROUND: Intraventricular cavernous malformations (IVCMs) are relatively rare benign vascular malformations. Patients may be asymptomatic or present with symptoms including headache, seizure, hemorrhage, and neurological deficits. We report two cases of patients with cavernomas in the third ventricle and at the foramen of Monro (FoM) and a systematic review of the literature to examine the clinical features and the efficacy of the current standard of care for these lesions. METHODS: A systematic review was performed according to PRISMA guidelines...

RATIONALE: Portal vein thrombosis is a complication after liver transplantation and cavernous transformation of the portal vein (CTPV) is a result of portal vein thrombosis, with symptoms of portal hypertension revealed by an enhanced CT scan. Meso-Rex bypass is an artificial shunt connecting the left portal vein to the superior mesenteric vein and is mainly used for idiopathic cavernomas. This technique is also used for post-transplant portal vein thrombosis in pediatric patients thereby bypassing obstructed sites of the extrahepatic portal vein...

BACKGROUND: Some glial tumors have been observed in association with different types of vascular malformations of the brain (angiogliomas). However, the association of ganglioglioma with other vascular malformations is extremely rare, with only few cases reported in the literature, one of which is referred to as "angioganglioglioma." CASE DESCRIPTION: Two patients presented with acute onset of neurological symptoms, with magnetic resonance imaging (MRI) finding of cavernoma of the left middle cerebellar penduncle, and small mass of the chiasmatic region, respectively...

Cerebral cavernous angioma or cavernoma is a benign vascular malformation, usually asymptomatic. It is infrequent and often its discovery is incidental, a so-called incidentaloma. However, these lesions can be symptomatic, causing headaches, epilepsy, cerebral hemorrhage and other neurological signs depending on the brain area involved. Frontal localization is responsible for psychiatric disorders, particularly the prefrontal region, leading to prefrontal syndrome, a condition common in all frontal lobe tumors...

Importance: The prevalence of cerebral cavernous malformation (CCM) is unknown. Case ascertainment in most previous studies was based on autopsy data or clinical convenience samples, often without detailed clinical or radiologic information. Objective: To determine the prevalence of CCM in a population-based sample of older adults. Design, Setting, and Participants: This prospective imaging study included 4721 participants aged 50 to 89 years who were enrolled between January 1, 2004, and December 15, 2015, in the Mayo Clinic Study of Aging, a longitudinal, population-based study of residents of Olmsted County, Minnesota...

Transjugular intrahepatic portosystemic shunt (TIPS) placement is a standard procedure for the treatment of portal hypertension complications. When this conventional approach is not feasible, alternative procedures for systemic diversion of portal blood have been proposed. A one-step interventional approach, combining minilaparotomy-assisted transmesenteric (MAT) antegrade portal recanalization and TIPS, is described in an adolescent with recurrent esophageal varice bleeding and portal cavernoma (PC). A 16-year-old girl was admitted to our Unit because of repeated bleeding episodes over a short period of time due to esophageal varices in the context of a PC...
