Orbital venous-lymphatic malformations (OVLMs) (previously referred to as 'lymphangiomas') are uncommon, benign cystic type I vascular malformations. OVLMs may remain clinically unapparent or might manifest in childhood with slowly progressive proptosis, periorbital swelling and displacement of globe. These malformations usually enlarge slowly . Usually presents as painless proptosis in middle-aged women. However, it can also present with pain, lid swelling, diplopia, lump, and recurrent obstructed vision
Vascular malformations of the orbit represent a set of uncommon diseases that usually create controversy among physicians leading to delay in diagnosis, treatment and referrals An orbital venous-lymphatic malformation is a rare congenital lesion, the clinical and radiological features of which have been highlighted by Liyanage et al
Lymphatic malformations, previously known as lymphangiomas, are benign vascular tumors usually diagnosed in early childhood that represent 1-3% of orbital masses. Histologically, lymphatic malformations consist of enlarged, nonencapsulated channels lined with a single layer of endothelium Orbital venous lymphatic malformations are isolated from the normal orbital vasculature and, unlike varices, are not affected by postural changes (, 22). However, they may be associated with intracranial vascular malformations, especially developmental venous anomalies (, 20) Vascular malformations are often found inside the orbit. Isolated venous malformations (frequently misnamed as cavernous hemangiomas) are the most frequent among these. However, also lymphatic and arteriovenous malformations can affect the orbit
At the time of sclerotherapy, a needle was guided into the venous malformation using ultrasound (US) guidance (Figure 2). Blood return was noted and an orbital venogram confirmed a venous malformation. A total of 2 mL of Bleomycin (15U/mL) was injected. A second procedure was subsequently performed about 4 months later Vascular anomalies of the orbit include venouslymphatic malformations (VLM). These lesions, often referred to as lymphangioma, are considered congenital and most commonly present in childhood. Approximately one-third are identified in the first weeks of life Dr Daniel J Bell ◉ and Dr Mohamed Saber et al. Orbital lymphangiomas, also known as orbital venous lymphatic malformations, are congenital benign orbital vascular malformations composed of variable venous and lymphatic component Description. A patient with orbital venous lymphatic malformation causing massive proptosis. MRI demonstrates an enhancing, T1 hypointense, T2 hyperintense, lobulated mass with small blood-fluid levels in the left medial orbit compressing the globe and causing bony deformation of the bony orbit Venous-lymphatic malformations are benign vascular malformations which can cause cosmetic and functional side effects like extraocular muscle dysfunction, strabismus, infection, amblyopia, and even visual dysfunction. Occasionally, intra-lesional hemorrhage leads to sudden change in size which affects adjacent structures

layed images, and do not involute. Orbital varices appear distended on images obtained with the patient prone or during the Valsalva maneu-ver. Venous lymphatic malformations show multiple ﬂuid-ﬂuid levels, enlarge during viral infections, and may manifest as chocolate-colored cysts after an acute hemorrhage. Arteriovenous malformations. Lymphatic malformations or lymphangiomas are benign (non-cancerous) vascular lesions made of fluid-filled spaces (cysts) thought to occur due to abnormal development of the lymphatic system. In general, lymphatic malformations are categorized into macrocystic, microcystic, or combined depending on the size of the cysts; they are also classified in superficial lesions known as lymphangioma. Description of Orbital Lymphangioma Hemangioma and venous lymphatic malformation are the two most common orbital vascular lesions seen in the pediatric patient. Orbital Lymphangioma are benign hamartomatous tumours and might have an aggressive nature. Lymphangioma is rare, and constitutes less than 7% of orbital tumours Selva D, Strianese D, Rootman J, et al.

Examples of the other classifications include primary orbital varices for Venous Flow malformations (Type 2) and arteriovenous malformations for Arterial Flow malformations (Type 3).  Along with classification based on the type of blood flow, lymphangiomas can also be classified based on the type of vascular lesion: venous, arterial, or. Venous-lymphatic anomalies (VLA) are rare and benign congenital lesions of the lymphatic system, composed of endothelial-lined lymphatic cysts. They are most frequently located in the region of the head and neck, and represent 4% of all orbital masses. In those patients with extensive orbital VLAs, a strong association with intracranial vascular anomalies has been reported Hemangioma and venous lymphatic malformation are the two most common orbital vascular lesions seen in the pediatric patient. Orbital Lymphangioma are benign hamartomatous tumours and could have an aggressive nature. Lymphangioma is rare, and constitutes less than 7% of orbital tumours. It usually presents with slow growth and a gradually. Venous malformations can allow blood to pool, which can lead to clot formation, infection, and inflammation. Lymphatic malformations are similar to venous malformations, but are formed by abnormally enlarged lymphatic vessels. Normal lymphatic vessels drain excess fluid from tissues and eventually recycle this fluid back into your veins

Intraorbital arteriovenous malformations (AVMs) are rare lesions that are thought to be congenital in origin. 1 They are derived embryologically from the arterial system, the venous system, or both. They are high-flow, progressively enlarging communications between arteries and veins that bypass normal capillary beds, usually with multiple feeder arteries, a central nidus, and numerous dilated.
Well-circumscribed orbital venous-lymphatic malformations with atypical features in children. Br J Ophthalmol. 2009; 93(5):656-9 (ISSN: 1468-2079) Gündüz K; Kurt RA; Erden E. AIM: To report well-circumscribed orbital lymphatic-venous malformations (VLMs) with atypical clinical, imaging and pathological features in four paediatric patients us malformations under this classification. Management of symptomatic lesions can be with surgical excision or stereotactic fractionated radiotherapy in selected cases. Beta-blockers including propranolol and topical timolol maleate represent first-line therapy for infantile hemangiomas, although surgery has a role in selected cases. Orbital venous-lymphatic malformations are problematic but. Venolymphatic malformations are typically treated by percutaneous sclerotherapy, with or without surgical adjunct. Different sclerosants are described in the literature, with bleomycin increasingly chosen because of its efficacy and favorable side effect. Patients with tongue or intra-orbital lesions are more prone to post-procedural.
If orbital venous lymphatic malformation is the true diagnosis, the images here may represent a particular subtype or a lesion that matured, subsequently taking on different sonographic findings. The patient's clinical status has improved; however, a tissue diagnosis has not been obtained Lymphatic malformations are groups of enlarged and/or misshaped lymphatic channels that do not work correctly. The lymphatic system consists of organs (spleen, thymus, tonsils and adenoids), lymph nodes and thin tubes (called lymphatic vessels) which carry lymphatic fluid. The lymphatic system is an important part of the immune system Purpose To assess the efficacy of sclerotherapy with sodium tetradecyl sulfate (STS; Fibrovein 1%) in superficial periocular venous and lymphatic malformations. Methods Eleven patients with low-flow venous and lymphatic malformations with extension predominantly to the eyelids, conjunctiva, and anterior orbit were selected. Sclerotherapy with STS was undertaken as an office-based procedure. Lymphangiomas are benign vascular malformations (venous-lymphatic malformations), usually diagnosed in early childhood, especially in the head-and-neck region but rarely involving the orbit. It usually presents at an early age, from infancy to the first decade of life and constituted 0.3%-1.5% of all histopathologically diagnosed orbital. Lymphatic malformations comprise 1-8% of all orbital masses and are characterized as macrocystic, microcystic, mixed, and venolymphatic subtypes. [ 1 , 2 ] Macrocystic malformations are characterized by cysts >1-2 cm in diameter, while microcystic malformations have smaller cysts that may not be visible on the US
Intraorbital venous-lymphatic malformations are present at birth, but tend not to be discovered clinically until early childhood when they enlarge as a result of either intralesional hemorrhage or lymphoid hyperplasia and result in acute proptosis. Approximately one-half of all patients with orbital LMs also complain of limited ocular mobility Orbital venous-lymphatic malformations (lymphangiomas) are postulated to be congenital, abnormal networks of lymphatic and venous vessels that arborize into adjacent tissues. 1 The pathophysiology of this entity, in particular the separation from primary orbital varices, has been the source of some controversy. 2-6 It is our view that venous-lymphatic malformations are hemodynamically. clinical presentations. This review focuses on some of the common orbital masses. Common vascular lesions that are reviewed include: capillary (infantile) hemangioma, cavernous hemangioma (solitary encapsulated venous-lymphatic malformation), and lym-phangioma (venous-lymphatic malformation) A 12-year-old girl had an orbital lymphangioma and ipsilateral persistent hyperplastic primary vitreous (recently termed persistent fetal vasculature). Persistent fetal vasculature, orbital combined venous lymphatic vascular malformations, and noncontiguous intracranial vascular malformations may reflect the same defect in embryonal vascular maturation occurring in different tissues

Combined venous lymphatic vascular malformation. Lymphangiomas are benign vascular tumors that most often appear during the first or second decade of life. These tumors may be found in the conjunctiva, the eyelids, the orbit, or elsewhere in the head and neck region. Spontaneous hemorrhage may be the initial clinical presentation causing sudden. formations in both orbits, with mass effect on the left side. The patient was started on a trial of the antiangiogenic agent sirolimus (also known as rapamycin), and after 6 months of treatment showed clinical improvement in proptosis supported by radiologic evidence of regression in the larger, left orbital mass, with stability of the smaller, right orbital mass. There are 11 published cases. Venous lymphatic malformation in an 11-year-old boy with progressive proptosis of the right eye and lateral displacement of the globe. (a) Axial unenhanced CT shows multiple fluid-fluid levels (arrows) within a lobulated, predominantly extraconal lesion, features typical of a lymphatic malformation with an intralesional hemorrhage
Orbital lymphangiomas can be associated with an orbital and/or intracranial arteriovenous malformation. Katz and colleagues attempted to explain this by stating that lymphangiomas represent a. Venous lymphatic malformation is another common orbital lesion within the paediatric population. Children with orbital venous lymphatic malformation typically present in childhood with slowly progressive proptosis, periorbital swelling and displacement of globe. It appears on MRI as an enhancing mass that crosses anatomic boundaries, such as.

For the treatment of a patient with an orbital venolymphatic malformation, we sought to optimize guid-ance by combining navigation assistance for needle place-ment with intralesional contrast medium injection for as-sessment of venous drainage LYMPHANGIOMA: A LONGSTANDING DILEMMAThere has been considerable debate in the literature about the origin of orbital lymphangiomas, whether they represent choristomas, hamartomas, orbital venous anomalies, combined venous lymphatic malformations, or distinct entities. Wright et al. (18) believe that most lymphangiomas represent congenital varices Dr. Verity is a Consultant Ophthalmic Surgeon, and Adnexal Service Director, Moorfields Eye Hospital, London.He is a Honorary Senior Clinical Lecturer, University College London.Trained in ophthalmology in the UK, Dr. Verity undertook two Fellowships in ophthalmic adnexal disease before joining the Consultant staff at Moorfields Eye Hospital in 2004.He is a Full Member of the British.
