Background: Hemangioma and vascular malformation are benign vascular lesions that often occur in cephalic and cervical region. Currently, surgical resection, laser therapy, angiographic embolization, use of steroids, and sclerotherapy are used as treatments. Case presentation: This study reports three cases of benign vascular lesions that are remarkably treated by sodium tetradecyl sulfate (STS) injection, of which occurred in oral cavity and around the mouth. Three percent of STS was diluted with 0.9 % of normal saline, and it was injected to the lesion site at least once. The result of treatment was evaluated based on clinical findings. Conclusion: Surgical treatment of hemangioma and vascular malformation occurred in oral cavity is not normally used because of esthetic issues and potential hemorrhage. On the other hand, sclerotherapy using STS is an effective therapy compare to surgical treatment. Despite the number of STS injection was different for each patient, all three patients had reached satisfactory level through the treatment with gradual diminution of lesions.

Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics.

More than half of the reported cases of congenital arteriovenous malformations involve the extremities. However, these are predominantly arteriovenous malformations of soft tissues. There are few studies on intraosseous arteriovenous malformations. The clinical features of vascular malformations are not well defined, but are likely to be extremely diverse. So, it is not easy to diagnose exactly and treat intraosseous arteriovenous malformations. The authors noted intraosseous arteriovenous malformation of tibia in a child and had a good result by the use of ethanol embolization. Therefore we include those results along with the literature review.

A 47-year-old man presented with a subarachnoid hemorrhage (SAH) and right cerebellar hematoma was referred for evaluation. Cerebral angiography revealed a distal anterior inferior cerebellar artery (AICA) aneurysm associated with an arteriovenous malformation (AVM). Successful obliteration and complete removal of the aneurysm and AVM were obtained using transcortical approach under the guidance of neuronavigation system. The association of a peripheral AICA aneurysm and a cerebellar AVM by the same artery is unique. The reported cases of conventional surgery for this disease complex are not common and their results are variable. Less invasive surgery using image-guided neuronavigation system would be helpful and feasible for a peripheral aneurysm combining an AVM of the posterior fossa in selective cases

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease that behaves as a slowly expanding lesion with a gradual onset. It is well established that CEIH is associated with arteriovenous malformations; however, CEIH associated with cavernous malformation (CM) is extremely rare. We herein report a case of CEIH associated with CM, and discuss its pathogenesis. A 12-year-old female was admitted to our hospital because of a one week history of progressive headache and nausea. Brain computed tomography scan and magnetic resonance imaging showed an intracerebral hematoma surrounded by edema in the right frontal lobe. One week later, her headache and nausea worsened, and a brain computed tomography scan revealed the enlargement of hematoma. A right frontal craniotomy was performed. The capsule, mass, and hematoma were totally removed. Histological examination confirmed the diagnosis of CEIH associated with CM. Immunohistochemical analysis revealed increased expression of vascular endothelial growth factor (VEGF) and the VEGF receptor-1 in the endothelium and fibroblasts. Our findings suggest that the activated VEGF pathway might have positively contributed to development of CEIH in the present patient.

To make better clinical diagnosis, authors reviewed 9 patients of nonchromosomal multiple malformation disorders with psychomotor retardation, who were evaluated at pediatric department of Yeungnam University hospital for recent 2 years. We could make clinical diagnosis in 5 patients out of 9 as Aarskog syndrome, Beckwith-Wiedemann syndrome, Hallermann-Streiff syndrome, Rubinstein Taybi syndrome and Weaver syndrome. But even in diagnosed cases, there were many discrepant findings in comparison with typical cases of reference literatures and family history was positive in only one case. Moreover we could not make diagnosis in 4 patients. Therefore we think it is necessary to make a survey of unique pattern, incidence, distribution and etiologic factors of malformation disorders in our country by geneticist and pediatrician as well as to improve the laboratory aids for better diagnosis and genetic counceling.

In the field of oromaxillofacial surgery, it is not common to meet arteriovenous malformation(AVM) patients. AVMs are the result of congenital abnormality, or the result of trauma of adjacent vessels. This patients need special care in surgical procedure. Also, they need management include clinical, radiographic, and angiographic assessment. We report a case of the AVM in right maxillary artery, who embolized PVA and obtained good result.

A 54-year-old female presented with a 4cm sized painless, submandibular gland area mass. Vascular lesion was suspected in computed tomography scan. Surgical excision was performed via retroauricular approach for its excellent cosmetic outcome. The vascular mass with peripheral focal calcification was clearly resected without complication such as bleeding or neural damage. Histopathological examination of the specimen revealed an arteriovenous malformation(AVM) with abnormal communications between arteries and veins without the normal intervening capillary bed. We report a successful excision of AVM in the submandibular space via retroauricular approach.

Objective: To report the effect of Korean medicine treatment on a facial palsy patient with a cavernous malformation. Methods: The patient was treated with herbal medicine (Jodeung-san, 釣藤散) and acupuncture. The degree of treatment was measured by the Yanagihara-scale and by mobility of the face. Results: During treatment, the patient’s symptoms were relieved and facial movement was improved. Conclusion: This clinical case study showed the effect of herbal medicine and acupuncture on symptoms of facial palsy.

After surgical operation in patients with arteriovenous malformation (AVM), normal pressure perfusion breakthrough (NPPB) is one of the major complications. Brain perfusion SPECT with acetazolamide stress was known to be useful to evaluate the vascular reserve in several neurological and neurosurgical conditions. The authors performed acetazolamide brain perfusion SPECT in patients with AVM and compared the brain perfusion in the post-operative clinical courses. The acetazolamide brain perfusion SPECT was helpful in defining the prognosis of the patients with AVM. We describe 4 patients with AVM who had acetazolamide brain perfusion SPECT to examine the prognosis.
