Radiation-induced vascular "malformations", designated cavernous hemangiomas/cavernomas ("RICHs"), are seldom biopsied and are usually diagnosed based on neuroimaging features. They are an increasingly recognized complication of both CNS external beam radiation therapy and stereotactic radiosurgery. We identified 13 patients with radiation-induced vascular "malformations" in our surgical neuropathology databases searched from 2000 to 2016; 4 had received their therapy during childhood; 5 had received radiosurgery...

Although transjugular intrahepatic portosystemic shunts are most frequently used for the management of portal hypertension, the surgical approach is preferred for symptomatic portal cavernoma cholangiopathy. We present the case of a 25-year old female patient with a portal cavernoma secondary to catheterization of the umbilical vein at birth. She had had two episodes of esophageal variceal bleeding, successfully treated by endoscopic banding. and an episode of acute cholangitis secondary to portal cavernoma cholangiopathy...

BACKGROUND: The spinal cord intramedullary cavernoma (SCIC) is a rare form of hemangioma that typically behaves as a space-occupying lesion resulting in neurological symptoms, including bladder and bowel dysfunction. To date, there have been few reports characterizing the clinical presentations and surgical outcomes of cavernomas at the C2 spinal level or the potential for resolution of bladder and bowel symptoms postoperatively. This case details the clinical course of a patient with a C2 cavernoma with an atypical neurological presentation and rapid improvement in both bladder and bowel function postoperatively...

Portal biliopathy refers to cholangiographic abnormalities which occur in patients with portal cavernoma. These changes occur as a result of pressure on bile ducts from bridging tortuous paracholedochal, epicholedochal and cholecystic veins. Bile duct ischemia may occur due prolonged venous pressure effect or result from insufficient blood supply. In addition, encasement of ducts may occur due fibrotic cavernoma. Majority of patients are asymptomatic. Portal biliopathy is a progressive disease and patients who have long standing disease and more severe bile duct abnormalities present with recurrent episodes of biliary pain, cholangitis and cholestasis...

Cavernous angiomas represent 5-12% of all spinal vascular lesions and 1% of all intramedullary lesions in pediatric patients. Intramedullary spinal cavernomas are relatively rare with only 24 cases reported till date to the best of our knowledge. A 15 -year-old boy presented to the clinic with acute onset motor weakness in all four limbs. He was diagnosed with multiple cerebral cavernomas and an acutely bleeding spinal cavernoma. Complete surgical excision of the spinal cavernoma was done. Postoperatively the patient's weakness gradually improved to a power of 4/5 in all his limbs over a period of 10 days...

BACKGROUND AND AIMS: The surgical treatment of intrinsic brainstem lesions remains a major challenge. In this article we present the results of using an infratentorial-supracerebellar (ITSC) approach for the resection of intrinsic ponto-mesencephalic lesions. MATERIALS AND METHODS: The authors reviewed the cases of 16 patients. In seven of them, a paramedian ITSC transcollicular approach was used to resect intrinsic mid-brain lesions, and in the other nine patients, an intermediate or lateral ITSC infra-trochlear approach was used for ponto-mesencephalic lesions...

AIM: Cavernous malformations in the spinal canal are rare. We review previous reports and present our own case of a cervical intradural extramedullary cavernoma, associated with a ventral cervical rootlet. METHODS: A 65 year old woman presented with radicular pain and paresthesias of the neck and right arm. PubMed search was used to compare her case to those previously published. RESULTS: The cavernoma was successfully removed with excellent recovery and no deficits...

Intramedullary spinal cavernoma is a rare vascular disease constituting 5-12% of all spinal vascular tumors. The clinical course is usually characterized either by an acute neurological deterioration, recurrent episodes of neurological deficits or by a slowly progressive neurological decline. Microsurgical removal is recommended when the symptoms become clinically relevant and the lesion appears accessible. In this article, we present a surgical technique to completely resect an intramedullary cavernoma with the aid of intraoperative electrophysiological monitoring and intraoperative real-time ultrasound guidance...

Portal vein thrombosis is observed in up to 10% of liver transplant candidates, hindering execution of the procedure. A dilated gastric vein is an alternative to portal vein reconstruction and decompression of splanchnic bed. We present two cases of patients with portal cavernoma and dilated left gastric vein draining splanchnic bed who underwent liver transplantation. The vein was dissected and sectioned near the cardia; the proximal segment was ligated with suture and the distal segment was anastomosed to the donor portal vein...

This is a case report of de novo development of two cerebral cavernous malformations adjacent to existing developmental venous anomalies. The development of cavernomas was noted over a follow-up period of 10 years. These developments happened during the course of staged endovascular management of a complex dural arterio-venous fistula along the right sphenoid wing. The patient presented with a proptosis secondary to lympho-haemangiomatous lesion of the fronto-orbital region and a high-flow right sphenoid wing dural arterio-venous fistula...

BACKGROUND: Malignant optic and chiasmatic gliomas are extremely rare, and are classified pathologically as anaplastic astrocytoma or glioblastoma multiforme (GBM). Approximately 40 cases of optic GBM in adults have been reported in the literature, and only five of them were described to originate from the optic chiasm. CASE DESCRIPTION: An 82-year-old male patient with a past medical history of diabetes mellitus type 2, melanoma, and bladder cancer presented with gradual vision loss of the left eye in a period of 1 month...

UNLABELLED: The mediobasal temporal region (MTR) is located near the brain stem and surrounded by the eloquent neurovascular structures. The supracerebellar transtentorial approach (STA) is safe access to the posterior MTR structures, however its use for resection of anterior MTR lesions still remains controversial. The article describes the technique and outcome of surgery for different MTR structures using STA. MATERIAL AND METHODS: The paramedian STA was used in 18 patients (13 females and 5 males) for 7 years...

Recently, great advances have been made in the surgical treatment of intramedullary spinal cord tumors (IMSCTs). Many articles have been published; but looking at the literature of the last 5 years, there are only descriptive reviews and no works in which a literature statistical analysis was performed. Here, we analyzed the literature to identify potential prognosticators of good functional outcome in IMSCT patients. To level out the selected studies, we stratified patients' neurological status as independent (ambulation possible without caregiver assistance) or disabled (cannot ambulate or can only ambulate with caregiver assistance)...

OBJECTIVE: To report a case of a patient with multiple cerebral cavernous malformations (CCM). OBSERVATION: A 22year old man with mild von Willebrand disease presented with two occipital CCM, one of them with acute hemorrhage. Genetic testing for CCM1-3 did not reveal a mutation. Over a period of 54months, the patient suffered 26 new CCM hemorrhages despite multiple treatment attempts including thalidomide, simvastatin and hemostatic factors. Only after initiation of propranolol, which has already been successfully used in three children with giant cerebral cavernoma, the occurrence of new CCM with hemorrhages was completely stopped already at dose of 30mg daily - now for a period of 26months and without any other medications...

INTRODUCTION: Hemorrhagic cavernous malformations involving the lateral pontine region require complex surgical considerations to maximize complete resection of the cavernoma and associated hemorrhage while minimizing morbidity. We describe our experience through the middle fossa rhomboid approach in 8 children with cavernomas involving the pons, with lateralized hemorrhages extending through the pontine parenchyma. METHODS: Eight children underwent this approach over a 10-year period at Rady Children's Hospital of San Diego...
