Disease Spectrum

Pancreatic arteriovenous malformation (PAVM) is a very rare and mostly congenital lesion, with less than 80 cases described in the English-published literature. It is defined as a tumorous vascular abnormality that is constructed between an anomalous bypass anastomosis of the arterial and venous networks within the pancreas. It represents about 5% of all arteriovenous malformations found in the gastrointestinal tract. Herein, we present a 64-year-old patient with symptomatic PAVM involving the body and tail of the organ, which was successfully treated by transcatheter arterial embolization. The disease spectrum and review of the literature are also presented.

<p class="abstract">Nasolabial cysts are rare, nonodontogenic soft tissue developmental cysts occur in the maxillary lip and nasal alar regions. Patients usually presents with an asymptomatic soft swelling with obliteration of the nasolabial fold. Due to it's origin from entrapped epithelium in an embryonic fusion plane developmentally, this cyst is considered to be a Hamartoma. Hamartomas are non-neoplastic malformations, or inborn errors of tissue development. They are characterized by an abnormal mixture of tissues indigenous to that area of the body. Complete surgical excision is the accepted method of treatment. This report aimed to present a case of nasolabial cyst hamartoma, which is rare in presentation.</p>

Abstract Background Epidermal cysts are common skin tumors that are composed of a keratinocytic cyst wall and central keratin material, which can occur anywhere in the body, especially on the face. However, there are no relevant reports of multiple epidermal cysts coexisting at the same location.Case presentation Here, we report one rare case of facial multiple epidermal cysts, who underwent sequential resection of all cysts. A 45-year-old male presented with facial multiple masses for over 2 years. Physical examination showed multiple cysts with varied sizes on the face. All cysts were smooth, dome-shaped, freely movable, and some of them were attached to the skin by a central pore. The histopathology revealed cysts in the dermis, the wall of which were composed of stratified squamous epithelium, and the cavity were filled with keratin. Therefore, the patient was diagnosed as facial multiple epidermal cysts.Conclusions This is the first well-documented case of multiple epidermal cysts on the face. We report this rare case to highlight that although epidermal cysts usually appear single, they may also appear multiple in the same location, especially in those patients with vigorous sebaceous gland function. Surgical excision is the first-line effective treatment for epidermal cysts.

✓ Two cases of spinal arteriovenous malformation (AVM) are reported because of a previously unobserved clinical feature: recurrent transient postprandial paresis of the legs. The authors believe the paresis was caused by chronic shunting of blood away from the cord and into the low-resistance AVM. Symptomatic cord ischemia might then be precipitated by vasodilatation in other areas of the body such as the splanchnic, brachial, or uterine vessels. We believe that in some instances this mechanism should be considered as an explanation for episodic neurological deficits seen in association with spinal AVM's.

Brain Arteriovenous Malformations

Brain arteriovenous malformations have a high risk of intracranial hemorrhage, which is a substantial cause of morbidity and mortality in patients with brain arteriovenous malformations. Although a variety of genetic factors leading to hereditary brain arteriovenous malformations have been extensively investigated, their pathogenesis is still not well elucidated, especially in sporadic brain arteriovenous malformations. The authors have reviewed the updated data of not only the genetic aspects of sporadic brain arteriovenous malformations, but also the architecture of microvasculature, the roles of the angiogenic factors, and the signaling pathways. This knowledge may allow us to infer the pathogenesis of sporadic brain arteriovenous malformations and develop pre-emptive treatments for them.

ResumoAs malformações arteriovenosas (MAV) são alterações congênitas dos vasos sanguíneos e, em casos raros, surgem apenas na idade adulta. A MAV apresenta comunicação direta entre uma artéria e uma veia que passam pelo leito capilar. Elas podem ocorrer em qualquer área do corpo e têm início e progressão graduais. O objetivo deste estudo é apresentar um caso cirúrgico de malformação arteriovenosa envolvendo a mucosa jugal direita de um paciente masculino de 16 anos de idade, tratado cirurgicamente em conjunto com o serviço de Cirurgia Vascular. O resultado pós-operatório foi satisfatório e a inter-relação entre os serviços de Cirurgia Maxilofacial e Vascular foi essencial para a realização de um procedimento cirúrgico mais seguro e previsível.Palavras-chave: Malformação arteriovenosa; cirurgia Maxilofacial; interdisciplinaridadeAbstractThe arteriovenous malformations (AVM) are congenital alterations of the blood vessels, and in rare cases, they develop only in adulthood. AVM present direct communications between an artery and a vein bypassing the capillary bed. They can occur at any area of the body and have gradual onset and progression. The aim of this study is to present a surgical case of arteriovenous malformation involving the right buccal mucosa of a 16-year-old male, which was managed with Vascular Surgery service. The postoperative result was satisfactory and interrelationship between Maxillofacial and Vascular Surgery services was essential for a safer and more predictable surgical procedure.Key-words: Arteriovenous malformation; Maxillofacial Surgery; interdisciplinarity

Purpose: High-resolution vessel wall magnetic resonance imaging (VW-MRI) could provide a way to identify high risk arteriovenous malformation (AVM) features. We present the first pilot study of clinically unruptured AVMs evaluated by high-resolution VW-MRI.Methods: A retrospective review of clinically unruptured AVMs with VW-MRI between January 1, 2016 and December 31, 2018 was performed documenting the presence or absence of vessel wall “hyperintensity,” or enhancement, within the nidus as well as perivascular enhancement and evidence of old hemorrhage (EOOH). The extent of nidal vessel wall “hyperintensity” was approximated into five groups: 0, 1–25, 26–50, 51–75, and 76–100%.Results: Of the nine cases, eight demonstrated at least some degree of vessel wall nidus “hyperintensity.” Of those eight cases, four demonstrated greater than 50% of the nidus with hyperintensity at the vessel wall, and three cases had perivascular enhancement adjacent to nidal vessels. Although none of the subjects had prior clinical hemorrhage/AVM rupture, of the six patients with available susceptibility weighted imaging to assess for remote hemorrhage, only two had subtle siderosis to suggest prior sub-clinical bleeds.Conclusion: Vessel wall “enhancement” occurs in AVMs with no prior clinical rupture. Additional studies are needed to further investigate the implication of these findings.

Haemorrhage is the most frequent revealing condition of brain arteriovenous malformations (bAVMs). We report a rare case of unruptured parietal bAVM revealed by spontaneous thrombosis of the main draining vein, responsible for a focal neurological deficit. The bAVM was embolized in emergency conditions; complete regression of the neurological symptoms was observed within five days after the embolization. Potential mechanisms of such spontaneous thrombosis of the bAVM’s main drainage pathway as well as an exhaustive review of the literature concerning this rare revealing condition are presented and discussed.

Abstract A follow-up study of 153 consecutive patients who underwent complete excision of an angiographically visualized intracerebral arteriovenous malformation was conducted. The follow-up period ranged from 0.5 to 10.6 years, with a mean of 3.8 years. The presenting clinical event was hemorrhage in about one-half of the patients and seizure in about one-third. There was a marked tendency for postoperative neurological deficits to improve with time, so that whereas the immediate postoperative rate of serious morbidity was 24.2%, only 7.8% of the patients were found to have serious morbidity at follow-up. An additional 3 patients had died. one of an unrelated carcinoma, making the mortality related to arteriovenous malformation 1.3%. The classification of Spetzler and Martin (43) was used retrospectively; the percentages of Grade I (easiest) through Grade V (most difficult) lesions were 7.8%, 22.9%, 28.8%, 26.8%, and 13.8%, respectively. The early result was well correlated to grade, with good or excellent results in 100%, 94.3%, 88.6%, 61%, and 28.6% of the patients in Grades I through V, respectively. At follow-up, 98.7% of the patients with arteriovenous malformations of Grades I, II, and III were in good or excellent condition. The late morbidity and mortality rates for the patients in Grades IV and V were 12.2% and 38.4%, respectively. Of the patients who did not have seizures before surgery, 8.2% had only one or two seizures during the immediate postoperative period, and 7.1% had late seizures that were well controlled with medication in all. Of the patients who had seizures before surgery, over half were either cured or greatly improved with respect to the seizures. In 32.7% there was no change in the frequency of the seizures, and in 12.7% the seizures were more frequent after surgery. There was no history of either proven or suspected intracranial hemorrhage in any of the patients during the entire follow-up period, which in the aggregate totalled 556.3 years.
