We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration...

AIM: To retrospectively statistically compare clinical and placental phenotypes of nonmacerated fetuses and live-born perinatal deaths in 3rd trimester pregnancies. METHODS: Twenty-five clinical and 47 placental phenotypes were statistically compared among 93 cases of nonmacerated (intrapartum, or recent antepartum death) 3rd trimester fetal deaths (Group 1), 118 3rd trimester neonatal deaths (Group 2) and 4285 cases without perinatal mortality (Group 3). RESULTS: Sixteen clinical and placental phenotypes were statistically significantly different between Group 3 and the two groups of perinatal deaths, which included eight placental phenotypes of fetal vascular malperfusion and eight other placental phenotypes of various etiology (amnion nodosum, 2-vessel umbilical cord, villous edema, increased extracellular matrix of chorionic villi, erythroblasts in fetal blood and trophoblastic lesions of shallow placentation)...

Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular malformation of the spinal cord, causing segmental lesions of the spinal cord due to venous ischemia. Functional outcomes of treatment in SDAVF patients are favorable, but the rate of improvement varies from 25 to 100%, which complicates prediction of the treatment outcome. AIM: the study aim was to identify a relationship between fistula localization and clinical manifestations and evaluate the effect of disease duration and severity of neurological impairments on immediate and long-term treatment outcomes, based on analysis of the literature and own data...

Lymphangioma is a congenital malformed lymphatic tumor that rarely involves the tongue. In our clinic, a 10-year-old female presented with lymphangioma circumscriptum involving the right two-thirds of the tongue. We administered an intralesional combination injection of triamcinolone, bleomycin, and bevacizumab as a treatment. Almost complete remission after combination therapy was achieved without complications such as edema, swallowing difficulties or recurrence. Bevacizumab, an inhibitor of vascular endothelial growth factor, was effective for the treatment of lymphangioma of the tongue in this case...

Epilepsia partialis continua (EPC) is a form of focal status epilepticus often refractory to anticonvulsant therapy. A wide range of abnormalities such as inflammatory, vascular, metabolic-toxic, developmental malformations, and neoplasia cause EPC. Linear nevus syndrome with hemimegalencephaly is one of the developmental malformations that can present with EPC.

Pulmonary arteriovenous malformation, which is defined as the presence of an ab-normal connection between the pulmonary artery and pulmonary vein, is rarely seen. Although it generally presents as a congenital condition, it may be accompanied by hereditary hemorrhagic telangiectasia. Clinical signs vary according to the amount of shunt in proportion to the number and size of the fistulae. Patients may present with cyanosis and respiratory trouble. If the disease remains untreated, it may result in cardiac failure and ineffective endocarditis, thereby leading to the rupture of the an-eurysmal fistula...

Kunal R Sinha, Gary Duckwiler, Daniel B Rootman
Orbital arteriovenous malformations (AVMs) are rare vascular lesions that may be managed with endovascular embolization followed by surgical resection. Embolization is often accomplished with n-butyl-2-cyanoacrylate (nBCA), which is considered to be a safe and effective liquid occlusive agent. Localized vascular inflammation has been associated with endovascular nBCA use in histopathologic studies, but reports of systemic hypersensitivity reactions following endovascular embolization with nBCA are rare. We present a case of a 26-year-old male who developed an intermittent systemic urticarial reaction without cardiopulmonary compromise beginning four weeks after nBCA embolization of an orbital AVM...

INTRODUCTION: Angiodysplasia is a common vascular abnormality of the gastrointestinal tract, found in the elderly and most frequently revealed by gastrointestinal bleeding. We report an original case of ileal angiodysplasia in an 83-year-old woman presenting as a bowel obstruction. CASE PRESENTATION: An 83-year-old woman with a medical history of chronic untreated anemia, presented with cardinal symptoms of bowel obstruction. Computed tomography revealed diffuse ileal wall thickening with multiple zones of stenosis, which were aggravated by an ileal perforation and associated with vascular abnormalities compatible with angiodysplasia...

Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders...

Spinal subdural hematomas (SSDHs) are rare and usually associated with bleeding diatheses, trauma, iatrogenic injury, spinal vascular malformations, or intraspinal tumors. We report a case of a 75-year-old male who developed a symptomatic lumbosacral SSDH after undergoing resection of a right temporal glioblastoma multiforme. The patient subsequently recovered and was discharged home. Over the next two weeks he developed progressively worsening symptoms of lower back pain, lower extremity weakness, and urinary retention...

A 2-year-old male intact Belgian Malinois was presented for exercise intolerance. A grade III/VI left basilar systolic murmur was detected. Echocardiography revealed moderate right atrial and ventricular dilation and increased pulmonic outflow velocity. Thoracic radiographs showed right heart enlargement and a dilated caudal vena cava. In addition, on the left lateral projection, an enlarged aberrant right cranial pulmonary lobar vein was suspected to be diverging ventrally from the course of the right cranial lobar bronchus and inserting more ventrally than normal in the region of the right atrium...

PURPOSE: Vessel enhancement algorithms are often used as a preprocessing step for vessel segmentation in medical images to improve the overall segmentation accuracy. Each algorithm uses different characteristics to enhance vessels, such that the most suitable algorithm may vary for different applications. This paper presents a comparative analysis of the accuracy gains in vessel segmentation generated by the use of nine vessel enhancement algorithms: Multiscale vesselness using the formulas described by Erdt (MSE), Frangi (MSF), and Sato (MSS), optimally oriented ux (OOF), ranking orientations responses path operator (RORPO), the regularized Perona-Malik approach (RPM), vessel enhanced diffusion (VED), hybrid diffusion with continuous switch (HDCS), and the white top hat algorithm (WTH)...

In the field of dysmorphology, achondroplasia is a well-known disorder. Sinus pericranii (SP), however, is not. The latter condition is a rare vascular malformation characterized by abnormal connections between the intracranial and the extracranial venous drainage pathways. The etiology of SP remains unclear, and yet, these defects can be present at birth, develop spontaneously later, or evolve following head trauma. Here, we report on a 2-year-old male with achondroplasia, SP, and craniocervical junction stenosis...

Activin A receptor like type 1 (ALK1) is a transmembrane serine/threonine receptor kinase in the transforming growth factor-beta receptor family that is expressed on endothelial cells. Defects in ALK1 signaling cause the autosomal dominant vascular disorder, hereditary hemorrhagic telangiectasia (HHT), which is characterized by development of direct connections between arteries and veins, or arteriovenous malformations (AVMs). Although previous studies have implicated ALK1 in various aspects of sprouting angiogenesis, including tip/stalk cell selection, migration, and proliferation, recent work suggests an intriguing role for ALK1 in transducing a flow-based signal that governs directed endothelial cell migration within patent, perfused vessels...

Preoperative transarterial chemoembolization has been widely used as an adjunct therapy for hypervascular metastatic spinal tumors. Several therapeutic iodized oil-based agents have been used in combination with anticancer drugs for injection into a feeding artery. Novel spherical agents with narrow-range particles and lower tendency to clump are preferred for the embolization of vascular malformations and hypervascular tumors. We describe the first case of cerebral embolization resulting in posterior circulation infarctions following transarterial embolization of a vascular vertebral body metastatic tumor with Embozene microspheres...
