Embolization as the treatment for a life-threatening mandibular arteriovenous malformation.

Mandibular arteriovenous malformation is a severe vascular pathological condition that may lead to life-threatening hemorrhages. In child and teenaged patients, a conservative treatment is preferred to avoid profuse blood loss and/or mutilating alterations in the still-growing patients' face. The aim of this article was to present a case of an 11-year-old boy with an arteriovenous malformation involving the left mandible and treated by means of endovascular embolization with direct lesional delivery of N-butyl-cyanoacrylate glue through transfemoral catheterization.

Osteoma em órbita / Orbital osteoma

O osteoma é uma tumefação benigna com crescimento lento, contínuo e apresenta-se como massa bem circunscrita, radiopaca, podendo ser lobulada. Caracteriza-se pela proliferação de osso cortical ou medular. A etiologia dessa lesão é desconhecida. Pode ser classificado em perióstico, central (endosteal) e extra-esqueletal. Clinicamente, é assintomático, mas pode produzir aumento de volume e assimetria facial. A tomografia computadorizada é o melhor exame de imagem para o diagnóstico. O tratamento é cirúrgico e somente indicado em pacientes com sintomas clínicos. Nossa proposta é apresentar um caso clínico em órbita cuja queixa era estética e de diplopia.

Osteoma is a benign tumor with continuous slow growing that appears as a well-circumscribed radiopaque mass that can be smooth or lobulated. It is characterized by proliferation of compact or medullar bone. Its etiology is unknown. It can be classified as periosteal, central or extra skeletal and, clinically, it is asymptomatic, but it can produce an increased volume, causing facial asymmetry. The computed tomography is the best image exam for this diagnosis. The treatment is surgical and only indicated to patients with clinical symptoms. Our purpose is to present a case report of a patient with aesthetic complaint and diplopia.
