Tomografía computarizada multidetector en el traumatismo facial: informe estructurado y observaciones clave para un abordaje sistemático / Multidetector computed tomography for facial trauma: structured reports and key observations for a systematic approach

Las fracturas faciales, relacionadas frecuentemente con accidentes de tráfico, agresiones, accidentes laborales o caídas, constituyen un considerable número de urgencias en nuestros hospitales y asocian, además, una elevada morbimortalidad. La tomografía computarizada multidetector es la técnica de imagen de elección por su amplia disponibilidad y rapidez, y porque permite tanto la caracterización de las fracturas faciales como de las complicaciones asociadas, incluyendo las de localización craneal. Es, por tanto, fundamental para orientar el manejo clínico y la planificación quirúrgica. En este trabajo se describe la anatomía radiológica de la región facial, destacando la importancia de los contrafuertes o arbotantes faciales, se ilustran los hallazgos característicos en las fracturas faciales, y se indican los puntos clave necesarios para su abordaje estructurado al realizar el correspondiente informe radiológico

Facial fractures, often related to traffic accidents, assault, work-related accidents, or falls, account for a considerable number of emergencies in our hospitals and are associated with high morbidity and mortality. Multidetector computed tomography (MDCT) is the imaging technique of choice in this scenario because it is widely available, fast, and useful for characterizing facial fractures and associated complications, including those located in the head. For all these reasons, MDCT is fundamental in the clinical management of these patients and in planning surgery. This paper describes the radiological anatomy of the facial region, underlining the importance of the facial buttresses, and it indicates the key points necessary for carrying out a structured approach and elaborating the corresponding radiologic report

Paraganglioma carotídeo maligno. A propósito de un caso / Malignant carotid paraganglioma: a case report

Los tumores del cuerpo carotídeo son neoplasias poco frecuentes, de lento crecimiento, muy destructivos y vascularizados, que tienen un origen neuroectodérmico. Los tumores malignos representan el 5-13% de los casos y presentan un comportamiento agresivo local con infiltración de los ganglios linfáticos adyacentes o metástasis a distancia. Presentamos el caso de un varón de 60 años al que en el estudio por dolor y parestesias en miembro superior se le realiza una resonancia magnética donde se visualiza una gran tumoración en el espacio carotídeo izquierdo, la cual se biopsió obteniendo el diagnóstico histológico de paraganglioma. Al realizar el estudio de extensión se identificó la presencia de metástasis pulmonares y óseas, lo que confirma la malignidad del tumor

Tumors of the carotid body are uncommon neoplasms that originate in the neuroectoderm. These tumors are slow growing but well vascularized and very destructive. Between 5% and 13% of carotid body tumors are malignant, behaving aggressively at the local level, invading the adjacent lymph nodes, and resulting in remote metastases. We present the case of a 60-year-old man who was examined for pain and paresthesias in his arm. Magnetic resonance imaging showed a large tumor in the left carotid space. Histologic study of a biopsy specimen from the tumor revealed that it was a paraganglioma. Further studies to determine the extent of disease detected metastases in bone and lung, confirming the tumor's malignancy
