Lymphatic malformations are relatively uncommon orbital lesions. Deep orbital malformation often goes unrecognized until causing clinical symptoms such as an intralesional hemorrhage. The superficial type, because of cosmetic concerns is brought to clinical attention much sooner For example, a lymphatic malformation within the orbit may present with progressive proptosis with acute deterioration in symptoms, the mass effect resulting in compressive optic neuropathy, diplopia/ocular muscle weakness, and orbital bruising. The clinical examination may reveal soft, non-tender masses on palpation with a doughy consistency
MRI features most consistent with fronto-orbital lymphatic malformation. The orbital lymphatic malformation is uncommon and considered as a congenital benign vascular malformation with variable lymphatic and venous components. It may increase in size progressively, producing proptosis of the affected eye with bone remodeling (as in this case) Orbital Venous-Lymphatic Malformation (OVLM) (Lymphangiomas) OVLM have been classified on the basic of anatomic location into three groups: superficial (conjunctiva and eyelid), deep (post-septal orbit), or combined lesions. Those that are superficial are usually predominantly lymphatic, while those that are deep are predominantly venous
Cavernous venous malformations of the orbit, also known as cavernous hemangiomas, are the most common vascular lesion of the orbit in adults. It is important to note that according to newer nomenclature (ISSVA classification of vascular anomalies) these lesions are merely known as slow flow venous malformations An orbital MRI was performed to evaluate the cause of the exopthalmus (Figure 1). Axial and coronal images revealed a lobulated, non-calcified, intraconal, orbital soft-tissue mass pushing the right globe anteriorly approximately 4 mm. The lobulated nature of the lesion suggested the diagnosis of an intraorbital venous malformation
. Imaging features of these lesions often reflect their tissue composition. Cavernous malformations (also known as cavernous hemangiomas), although not true neoplasms, are the most common benign adult orbital tumor 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)
Orbital AVF is the only condition that may be confused with orbital AVM on radiology and angiography. Orbital AVFs may be traumatic or spontaneous and are limited to the orbit, with no connection to the cavernous sinus. 41 These lesions can be differentiated from orbital AVMs on angiography: AVFs demonstrate a direct arteriovenous connection. Orbital varices are venous malformations of the orbit caused by vascular dysgenesis. They consist of a plexus of thin-walled distensible low flow vein-like vessels that are commonly intrinsic to the normal circulation. They are considered to be hamartomatous This neoplasm usually manifests in young children, grows quite rapidly, and is fairly vascular. Vasculogenic lesions are common orbital lesions in newborns and young infants. The most prevalent of these are infantile hemangioma, a true neoplasm, and venous-lymphatic malformation, a developmental anomaly
Lymphatic Malformation Treatment and Procedure Options Lymphatic malformations are now most often treated using interventional radiology minimally-invasive techniques designed to ablate (or kill) the cysts within the body. In this situation, a chemical injected into the lymphatic malformation cyst kills it Orbital varices appear distended on images obtained with the patient prone or during the Valsalva maneuver. Venous lymphatic malformations show multiple fluid-fluid levels, enlarge during viral infections, and may manifest as chocolate-colored cysts after an acute hemorrhage
Background: Percutaneous sclerotherapy is an alternative to surgery for the treatment of orbital lymphatic malformations (LMs). We present a large series of patients undergoing sclerotherapy for macrocystic LMs with detailed visual acuity (VA) outcome data Orbital venous lymphatic malformation (lymphangioma) healed with intra-lesional bleomycin Arch Soc Esp Oftalmol . 2019 Nov;94(11):e81-e82. doi: 10.1016/j.oftal.2019.07.008 Purpose: Bleomycin sclerotherapy has been shown to be a viable treatment for lymphatic malformations. However, its use for these lesions confined to the orbit is becoming increasingly documented in the literature Orbital lymphatic malformations (LMs) are a unique subtype of vascular anomaly that can swell and lead to blindness if left untreated in the acute setting. Detrimental acute and chronic effects of the malformation on vision suggest that treatment should be considered pre-emptively rather than in the acute setting Although venolymphatic malformation (previously known as lymphangioma) is a differential consideration, the prominent flow voids and vessel associated with this lesion do not favor this diagnosis [1, 8-12]. Abnormality of orbital vessels often suggests orbital or extraorbital disease and prompts a search for the cause
An orbital venous-lymphatic malformation is a rare congenital lesion, the clinical and radiological features of which have been highlighted by Liyanage et al. 1 We present our surgical experience. Retro-orbital lesions are treated in the presence of an ophthalmology attending, with careful pre- and post-procedure globe pressure measurements performed and close post-procedure clinical ophthalmologic observation. Lymphatic malformations can be so microcystic that they appear solid on imaging and diffusely infiltrative bar lymphatic malformation. The other two patients (case 2 and 3) presented with lymphatic malformations resembling symp-toms of orbital complications of a rhinosinusitis with loss of vi-sion. In both cases the masses were completely resected via lat-eral orbitotomy; histologic examination confirmed the diagnosis of lymphatic malformation In preparing this review, we conducted a Medline and PubMed search of the medical literature for the period between January 1978 and July 2014 using the following key words in various combinations: vascular anomaly, vascular malformation, orbital lymphangioma, orbital lymphatic malformation, orbital lymphatic-venous malformation.

Imaging is not typically performed for primary assessment of CMs, but rather to look for associated syndromic anomalies. • Lymphatic malformations (LMs): These lesions are composed of dilated lymphatic channels and cysts and are further categorized as macrocystic, microcystic or mixed (Figure 3). The archaic term cystic hygroma. Diagnosis: Intraorbital Lymphatic Malformation Vascular lesions account for 5-20% of all orbital masses, and the two most common orbital vascular lesions are venous malformations (formerly known as cavernous hemangiomas) and lymphatic malformations (LM) ( formerly known as lymphangiomas)
After observation, serial imaging and repeat ophthalmology follow up for over 1 year, the working diagnosis became orbital venous lymphatic malformation. The sonographic features of orbital venous lymphatic malformations are smooth well circumscribed lesions with high echogenicity [7, 8], and not consistent with the POCUS images obtained O rbital lymphatic-venous malformations (LVMs), so-called lymphangiomas, are currently classified based on the International Society for the Study of Vascular Anomalies classification as slow-flow vascular malformations and represent 1%-3% of all orbital masses. 8,13 The majority are mixed LVMs and have a variable venous component with a variable systemic venous outflow. 8,9 Because of their.
INTRODUCTION. Lymphatic malformations are benign malformations of the lymphatic system which represent between 1% and 8% of all orbital masses .Although different theories have been suggested, the aetiology of lymphatic malformations remains unclear .Lymphatic malformations in general have no predilection for sex, however, lymphatic malformations of the orbit seem to be slightly more. Lymphatic malformation in the orbital cavity and surrounding region often causes disfigurement and visual problems. To better clarify the evolution and treatment of this condition, the authors studied a retrospective cohort of 42 consecutive patients seen between 1971 and 2003 and analyzed anatomic features, complications, and management INTRODUCTION: Orbital lymphatic malformations (OLMs) are a unique subset of head and neck low flow vascular malformations, located either in the periorbital region or in the closed orbital cavity. We discuss our experience of minimally invasive strategies of treatment using advanced imaging and Bleomycin sclerotherapy to effectively treat these. The most important imaging tool is contrast-enhanced MRI.  This diagnostic test, which requires sedation or general anesthesia for children younger than 6 years, demonstrates the extent of the lesion and helps to differentiate between hemangiomas and venous, lymphatic, and arterial lesions. It also may help to differentiate between a vascular lesion and a nonvascular lesion, such as those.

lymphatics, therefore is theorized that orbital lymphatico-venous malformations are originated fromprimary orbital varices or from lymphatic or venous systems of the periorbital structures5. Diagnosis is established with clinical features and imaging studies, including orbital ultrasonography, CT scan and MRI. In th interventional radiology procedures.2 But lymphangiomas are diverse and unpredictable; even with treatment, long-term visual and cosmetic out-comes are often unsatisfactory. In recent years, clinicians have searched for—or come across—new approaches that may help in some cases. Possible Presentations Also called lymphatic malformations
Orbital lymphatic malformations (OLMs) are rare low-flow vascular anomalies representing 1-4% of all orbital lesions, primarily seen within the first decade of life [1, 2].Lesions can be classified as macrocystic (> 1 cm), microcystic (< 1 cm) or lesions with mixed morphology and orbital margin(n=1) veno-lymphatic malformations, and retrobulbar cystic teratoma(n=1).

Molding of the bone by a well-circumscribed orbital mass is highly suggestive of a congenital lesion (e.g., dermoid cyst and lymphangioma) or slowly growing benign lesion (i.e., cavernous malformation, neurofibroma, neurilemmoma, and benign lacrimal gland tumor) 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. Characteristic imaging features may help distinguish among lesions that have overlapping 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 CT is an important modality of orbital imaging. It provides volumetric cross-sectional image acquisitions. It is useful for orbital trauma to assess bony fracture or extraocular muscles entrapment and in intra orbital foreign body localization.

Vascular malformations are a more heterogeneous group of le - sions that consist of capillary, venous, arterial and lymphatic elements that may also occur in combination. Though clinical presentations neces-sarily differ based on the specific typ Orbital Vascular Malformations - Overview These no-flow lesions of venous/ lymphatic proliferation occur mainly in the first or second decade of life. They tend to start in the supero-nasal quadrant of the orbit and more than 50% affect the conjunctiva causing lymphangiectasias. Lymphangiomas can cause slow, progressive painless proptosis. Advanced imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scanning and ultrasound may be used to evaluate the extent of a lymphatic malformation after birth. An MRI uses a magnetic field and radio waves to produce cross-sectional images of particular organs and bodily tissues 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 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
