Massive Vascular Malformation in Head and Neck Region-A Rare Case Report with Review of Literature
https://www.ijrrjournal.com/IJRR\_Vol.7\_Issue.2\_Feb2020/Abstract\_IJRR0042.html, 2020
Vascular Malformations are rare anomalies occurring in the Head and Neck region and rarest to be found intraorally. They are usually unnoticed in initial stages of life but may be progressive in later stages of life. Venous malformation is the most common type of vascular malformation affecting 1-4% of individuals worldwide. We present a very rare case of 37 year old adult male with massive venous malformation involving tongue, soft palate, retromolar region, nasopharynx, larynx and respiratory tract. Since the lesion is involving respiratory tract and larynx, there is every possibility of respiratory wall collapse and distress and loss of voice after sclerotherapy. Therefore it was decided to keep the patient is kept under regular observation/follow-up. This case is being reported because of its peculiar clinical presentation with involvement of vital organs.
Imaging findings of vascular lesions in the head and neck
Diagnostic and Interventional Radiology, 2014
Vascular lesions of the head and neck include vascular neoplasms, vascular malformations, and hypervascular lesions, derived from nonvascular soft-tissue elements. We retrospectively evaluated magnetic resonance imaging and computed tomography images of vascular lesions located in the head and neck. Twelve patients (seven males, five females) aged 1-68 years (mean age, 35.25 years) were included in this study. Most of the vascular lesions in our study were histologically diagnosed. The lesions were as follows: a hemangioma located in the parotid space (n=1); a hemangioendothelioma located in the parotid space (n=1); a hemangiopericytoma located in the larynx (n=1); a juvenile angiofibroma located in the nasopharynx (n=1); a glomus tumor located in the carotid bifurcation (n=1); venous malformations located in the parapharyngeal space, the pterygoid area, the orbital space, and the larynx (n=4); lymphatic malformations located in the parotid space and the supraclavicular area (n=2); and an arteriovenous malformation located in the infratemporal fossa (n=1). We present rare vascular lesions of the head and neck, which have typical radiological findings.

The clinical presentation of low flow vascular malformations of the head and neck (LFVM) can range from a birthmark to severe disfigurement, functional impairment or relevant hemorrhage. The values of Brightness mode (B-mode) ultrasound and Doppler sonography in the investigation, identifying and differentiating of these lesions has been sparingly documented in the literature. This study evaluates the sonografic features of different morphological subtypes of LFVM. This is a 2-year retrospective study of 51 patients who presented with LFVM based on routine ultrasound exam in the context of their clinical consultation. Diagnosis was based on the clinical and histological findings. B-mode, color coded duplex and spectral Doppler measurements were performed for venous, lymphatic, capillary, and mixed venous-lymphatic lesions of the head and neck. The echogenicity of the majority of venous malformations was heterogenic, of most lymphatic malformations hypoechoic, and of all capillary malformations isoechoic. Blood flow was detected in only 11 cases (36.7%) of venous malformations with a monophasic pattern. There was a statistical significant difference in the mean minimum and maximum Doppler shifts between venous and lymphatic malformation for cases when the blood flow was evident. No statistical significant difference in Doppler parameters existed between capillary and lymphatic, neither between venous and capillary nor mixed malformations. Phleboliths were present in eight cases (26.7%) of venous malformations and were not detectable in any other subtype of LFVM. The detection of flow in ultrasound was only possible in a small portion of LFVM. When considering differentiating among LFVM, features such as the echogenecity, spectral Doppler wave forms, and the evidence of phleboliths contribute to establish the correct diagnosis.
Vascular lesions of the Head and Neck: A Review
2015
Vascular masses which are capable of causing significant abnormalities and life threatning conditions are heterogeneous group of lesions derived from blood vessels with differing histologies, clinical courses, imaging appearances and treatment options,with vascular malformations always present at birth and growing in proportion to body growth and never regress spontaneously. In the present review article , an attempt has been made to draw attention to the current classification, terminology, clinical features, natural history, diagnosis, various syndromes associated and management of these lesions.
Head and neck vascular anomalies in children
International Journal of Pediatric Otorhinolaryngology, 2009
Vascular lesions are the most common congenital and neonatal abnormalities. The aim of this work is to point out differences between various vascular anomalies, in order to define accurate diagnosis, and to present different therapeutic options now used for the treatment of the vascular lesions in children. According to biological classification described by the work of Mulliken and Glowacki there are two major types of vascular abnormality: haemangioma and vascular malformation. Haemangioma is a distinct biologic tumour entity characterised by rapid endothelial proliferation shortly after birth. The lesion is absent at birth and growth in early infancy, followed by a spontaneous resolution in childhood. Vascular malformations are structural anomalies that have a normal growth rate and endothelial turnover. According to the morphology of the vessels and the flow rate we distinguish: slow-flow and fastflow vascular malformation. The authors document their personal experience in diagnosis, clinical evaluation, treatment and follow-up of the vascular lesions.
Angiomatosis – A case report in comparison with vascular malformation
International Journal of Dentistry Research
Angiomatosis is a diffuse vascular lesion involving multiple tissue planes. Its infiltrative nature makes surgical removal difficult and has high recurrence rate. Histopathologically, consists of proliferating blood vessels within or adjacent to major vessels. Here we present a case report of angiomatosis with a clinical diagnosis as vascular malformation.
A 16-year retrospective study of vascular anomalies in the head and neck region
Head & Face Medicine
Summary Depending on the diagnostic modality, the classification of vascular anomalies varies and so does the nomenclature. The ‘International Society for the Study of Vascular Anomalies’ (ISSVA) is the most widely accepted classification in the literature and is mainly based on the radiologic and clinical presentation. The aim of this article is to review the clinical practice of diagnosis and treatment of vascular anomalies in the head and neck region in a university hospital, with special focus on the nomenclature. All patients with a vascular anomaly presenting to the department of oral and maxillofacial surgery were reviewed in a retrospective manner. Nomenclature, diagnostic process, lesion characteristics, treatment and outcome were examined. The lesions were (re)classified according to the ISSVA classification. A total of 185 patients were identified, of which 12.4% (n = 23) had a congenital anomaly. After reclassification, the most common lesions were venous malformations (...
Head and neck vascular malformations: time-resolved MR projection angiography
Neuroradiology, 2003
Extracranial vascular anomalies can be divided into haemangiomas and vascular malformations. The latter can be subdivided on the basis of the predominant type of vascular channels. Separation of high- and low-flow vascular malformations is of clinical importance. We report preliminary observations on time-resolved magnetic resonance projection angiography (MRPA) of vascular malformations of the head and neck. We examined eight patients with vascular anomalies of the head and neck. On MRPA the time between the early arterial phase and enhancement of the malformation could be used to distinguish high- and low-flow lesions. High-flow arteriovenous malformations showed early, intense enhancement. Venous malformations were either not visible on MRPA or showed late enhancement of veins. One patient was examined after embolisation of an arteriovenous fistula of the mandible. Normal MRPA was taken to indicate absence of a residual lesion.
