“…Cavernous hemangiomas (venous malformation) are most often located in the lateral wall of the nasal cavity and the anterior nasal septum, and they tend to occur in adult men [15]. We found only 1 case of AVM in the nasopharynx of an 8-year-old boy and only 1 case of AVM in the maxillary sinus in a published report [16,17]. Intravascular papillary endothelial hyperplasia in the sinonasal region has also been rarely reported [18].…”

Nasopharyngeal Capillary Arteriovenous Malformation with Ancient/Symplastic Change: A Simulator of Malignancy

et al. 2016

There are only 8 published cases of symplastic hemangioma (SH), a relatively recently described, distinct benign entity characterized by pleomorphic vascular smooth muscle and interstitial cells in a pre-existing, long-standing vascular lesion. Seven of these cases were of SH in cutaneous locations, and 1 case was described in the mediastinum. We report the case of the 12-year-old girl with a nasopharyngeal tumor mass with prominent symplastic changes arising in the background of a combined capillary arteriovenous malformation. After critical analysis of all published cases of SH, it is clear that these lesions commonly represent capillary arteriovenous malformations (CAVM) with ancient/symplastic changes according to current terminology proposed in the classification required by the International Society for the Study of Vascular Anomalies (ISSVA). This is the first such lesion reported in a mucosal location and presenting in the pediatric age group. CAVM with ancient/symplastic change follows a benign clinical course, but it can simulate a malignant vascular tumor.

“…Mostly, AVMs are congenital malformations, but are clinically relevant later in life and are frequently diagnosed at around 19 years of age with no sex-related association [1,2]. AVMs can arise in any part of the body; they are commonly located in the head and neck region and rarely in the nose [3].…”

Arteriovenous malformation (AVM) is a vascular malformation with an abnormal capillary shunt between the arterial and venous systems. AVMs can arise anywhere on the body, and are occasionally located in the head and neck. However, AVMs of the nose are considerably rare. Most cases of AVMs of the nose have no symptoms, but some cases show epistaxis and nasal obstruction. Furthermore, a differential diagnosis between hemangioma, lymphangioma, and AVM is important. In cases of AVMs, especially on the face, surgeons should consider cosmetic factors and choose an appropriate plan of treatment. We report the case of a 22-yearold male who presented with an asymptomatic, palpable mass on the nasal dorsum and was successfully treated with transcatheter arterial embolization and sclerotherapy.

“…Pre-operatively deciding the extent of the resection of the AVM is crucial. Magnetic resonance imaging is used to determine the extent of the soft-tissue involvement, while computed tomography is able to delineate any bone involvement (10). Selective angiography is useful for the investigation of AVM, as it can identify specific vascular abnormalities and demonstrate the flow characteristics, feeding vessels and dangerous anastomoses (11).…”

“…A multidisciplinary approach is recommended for the management of an AVM (2). The combined use of a complete surgical excision and prior superselective embolization is the treatment of choice for AVMs (10,11,13). It has been shown that it is best for the complete surgical resection to be performed within 48 h of highly selective embolization, as the resulting inflammation neutralizes hemodynamic benefits, making surgery more challenging (2)(3)(4).…”

Radial forearm and forehead flap reconstruction following resection of a nasal arteriovenous malformation: A case report

Arteriovenous malformation (AVM) is a structural vascular abnormality in which the arterial vasculature connects with the venous vasculature without capillary connections. AVM confined to the nasal cavity is considerably rare. Blurred vision can be one of the associated symptoms. A combined approach of complete surgical resection with prior superselective embolization is the treatment of choice. Following resection, the reconstruction of facial defects, particularly in the nasal area, is challenging. The present study reports the rare case of a patient with an AVM in the nasal cavity, in which embolization, resection and flap reconstruction were performed. Embolization and complete surgical resection were used to avoid recurrence. Subsequently, a combination of free radial forearm and forehead flaps was used for the reconstruction of the nasal defect, without prosthesis. To the best of our knowledge, this is the first report of AVM confined to the nasal cavity, managed by a combination of free radial forearm and forehead flap reconstruction following complete resection. The cosmetic results of the procedure were acceptable.
