When performing the panoramic radiography, an atypical shaping of the mandibular condyle was detected. For the correct diagnosis, a cone-beam computed tomography was requested. The axial, sagittal, and coronal tomographic sections clearly showed the structure and its position in relation to the skull. The exam showed unilateral hyperdense masses on the left, in the form of mediolaterally oriented secondary condylar heads. Although they were adjacent to the condylar head, a constriction between them was observed in the superior condylar pole region. This image analysis, associated with the absence of functional changes and symptomatology, was decisive for the diagnosis of a bifid condyle, as it allowed to exclude any pathological alteration. As its etiology is diverse, this type of anatomical variation is usually found in routine imaging exams, as in the present study. The bifid condyle can be considered a differential diagnosis of condylar hyperplasia, osteochondromas, or alterations related to temporomandibular dysfunction in two-dimensional radiographic exams.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo No presente relato de caso, o paciente compareceu à Clínica Cirúrgica da PUC-MG para extracção de terceiros molares. Ao realizar radiografia panorâmica, foi detetada uma formação atípica do côndilo mandibular. Para o diagnóstico correto, foi solicitada uma tomografia computadorizada de feixe cónico e, nas seções axial, sagital e coronal, foi possível visualizar claramente a estrutura e sua posição em relação ao crânio. O exame mostrou massas hiperdensas unilaterais à esquerda, na forma de cabeças condilares secundárias orientadas mediolateralmente. Embora estivessem adjacentes à cabeça condilar, uma constrição entre eles foi observada na região do pólo condilar superior. Essa análise de imagem, associada à ausência de alterações funcionais e sintomatologia, foi decisiva para a conclusão do diagnóstico de côndilo bífido, pois permitiu excluir qualquer alteração patológica. Como sua etiologia é diversa, geralmente esse tipo de variação anatômica é encontrado nos exames de imagem de rotina, como no presente estudo. Essa variação anatómica pode ser considerada um diagnóstico diferencial de hiperplasia condilar, osteocondromas ou alterações relacionadas à disfunção temporomandibular em exames radiográficos bidimensionais.]]></p></abstract>
