Cavernous hemangiomas are not true vascular tumors, but rather are slow-flow venous malformations (VMs). They are present at birth as nonproliferating vascular birthmarks composed of anomalous ectatic venous channels. VMs have often been incorrectly called cavernous hemangiomas and cavernous angiomas. These terms have for a long time lead to confusion with the more common proliferating or true hemangioma of infancy. VM has been reported to arise at all sites including skin and subcutaneous layers of the head and neck, face, extremities, liver, gastrointestinal tract, and even the thymus...

Vein of Galen aneurysmal malformations (VGAMs) are rare vascular malformations occurring commonly in the pediatric age group. They comprise only 1% of all intracranial vascular malformations, but in pediatric population, they represent 30% of all intracranial vascular malformations. They are of two types-mural and choroidal. Choroidal type of VGAM is more primitive and most severe form of disease. It usually causes high cardiac output failure in newborn period because of multiple high flow fistulas. Adult presentation of choroidal type VGAM is very rare, and only few cases have been reported in literature so far...

Cerebral cavernous malformations (CMs) are vascular malformations affecting any part of the central nervous system. Clinical data and surgical outcomes for 27 pediatric patients with CM-related epilepsy were retrospectively reviewed. The mean age of onset was 12.71 ± 4.09 years, and the mean duration of epilepsy was 2.34 ± 1.95 years. All 27 patients were treated with microsurgery for resection of the CMs, and the hemosiderin rim, and the secondary epileptogenic zone if necessary. The mean follow-up period was 6...

The modern application of interventional radiology techniques is revolutionizing the treatment of the vascular malformations of the head and neck. In fact, the morbidity related with the surgical extirpation of the malformation might be drastically reduced with the use of an endovascular approach. The present report describes the case of a 11 years old male affected by a large intraosseous arteriovenous malformation of the mandible. The coil embolization of the main drainage vein caused the spontaneous regression of the lesion and avoided a mutilating surgery and severe psychological sequels...

Vascular anomalies are localized defects of morphogenesis that can affect lymphatic and blood vessels. They are generally called birthmarks, typically observed soon after birth and occurring in up to 10% of children. Based on their clinical and histological characteristics, they are classified into vascular tumours and vascular malformations. The most common malformations are venous malformations (VMs) resulting in chronic vascular diseases that can be associated with significant morbidity necessitating often demanding and repeating clinical management...

We present an extremely rare case of a 53-year-old woman with an intraoral superficial haemosiderotic lymphovascular malformation (SHLM), also known as hobnail haemangioma. SHLM is a rare, benign, vascular tumour first described as targetoid haemosiderotic haemangioma, with only a handful of cases reported to present in the oral cavity. The diagnosis was established following complete surgical excision of the lesion, and after 14 months, there are still no signs of recurrence. Although SHLM is an uncommon condition, accurate and timely diagnosis is valuable in distinguishing these lesions from their more serious competing differential diagnoses...

OBJECTIVE: Venous aneurysms are uncommon vascular abnormalities that may be identified anywhere in the body. Historically, they were often misdiagnosed as soft tissue lesions, but with the advent of readily available noninvasive imaging (such as duplex ultrasound), they can now be easily identified. Our aim was to review the presentation of venous aneurysms, available imaging modalities for defining them, and management. METHODS: The English-language literature before March 2017 was reviewed, and only reports of primary venous aneurysms of the deep veins were included...

Background: Lymphatic vascular malformations (LVM) or formerly called lymphangiomas are congenital malformations present in about 1 out of 6000 to -16000 births. The most relevant classification system for lymphangioma management is based on the size of the cysts. Spontaneous resolution is uncommon; thus, expectant management is not recommended. The classic treatment is excisional surgery, but it can affect adjacent structures or have relapses, so, sclerosing substances like OK-432 are being studied...

Eight-and-a-half syndrome, a combination of one-and-a-half syndrome and ipsilateral facial palsy, was first described by Eggenberger in 1998. Intracranial capillary telangiectasia (ICT) is a rare type of latent cerebral vascular malformation characterized by a number of small, dilated, and thin-walled blood capillaries with normal brain tissues between them. Susceptibility weighted imaging is the recommended diagnostic method to detect ICT. Oommen once reported 1 case about pontine hemorrhage causing Fisher one-and-a-half syndrome with facial paralysis...

INTRODUCTION: There is increasing acknowledgement that surgical care is important in global health initiatives. In particular, neurosurgical care is as limited as 1-to-10 million people in parts of the world. We performed a systematic literature review to examine the worldwide incidence of central nervous system vascular lesions (CNS-VL) and a meta-analysis of aneurysmal subarachnoid hemorrhage (ASAH) in order to define the disease burden and inform neurosurgical global health efforts...

After thickening of the cardiac chamber walls during embryogenesis, oxygen and nutrients can no longer be adequately supplied to cardiac cells via passive diffusion; therefore, a primitive vascular network develops to supply these vital structures. This plexus further matures into coronary arteries and veins, which ensures continued development of the heart. Various models have been proposed to account for the growth of the coronary arteries. However, lineage-tracing studies in the last decade have identified 3 major sources, namely, the proepicardium, the sinus venosus, and endocardium...

Vascular malformations are classified primarily according to their flow characteristics, slow flow (lymphatic and venous) or fast flow (arteriovenous). They can occur anywhere in the body but have a unique presentation when affecting the female pelvis. With a detailed clinical history and the proper imaging studies, the correct diagnosis can be made and the best treatment can be initiated. Lymphatic and venous malformations are often treated with sclerotherapy while arteriovenous malformations usually require embolization...

Vascular malformations are poorly recognized constitutional anomalies which arises during early childhood. Several classifications tried to draw a distinction across the different entities. Recent advances in molecular biology have contributed to the update of their nosology. Syndromic vascular malformations are an example: while Klippel-Trenaunay syndrome, Proteus or CLOVES syndrome share many common features, understanding of pathological mechanism and specially the role of the PIK3/AKT/mTOR pathway enables us to rethink their classification...
