RESUMO
Resumen El trauma del globo ocular es una emergencia frecuente en los servicios de urgencia. Su importancia radica en el riesgo de la pérdida visual e incluso la ceguera. La valoración clínica del trauma ocular es un reto diagnóstico. Clínicamente se pueden realizar algunos diagnósticos, pero muchas veces se requiere de la valoración imagenológica para determinar lesiones asociadas. La tomografía computada (TC) permite el diagnóstico oportuno de las lesiones traumáticas del globo ocular, especialmente la presencia de cuerpos extraños. Adicionalmente, el conocimiento de los hallazgos imagenológicos en otras patologías oculares que pueden confundirse con patologías traumáticas es importante para hacer un adecuado diagnóstico diferencial. El objetivo del presente artículo es realizar una revisión de los hallazgos por imagen de las lesiones traumáticas del globo ocular.
Abstract Traumatic ocular injuries are common cause of emergency room visits. Injuries of the globe are a significant cause of blindness and visual deficits. The clinical assessment of globe trauma can be challenging. Some diagnoses can be made clinically, but imaging assessment is often required to determine associated lesions. Computed tomography (CT) allows the timely diagnosis of traumatic injuries of the globe, especially the presence of foreign bodies. In addition, knowledge of the imaging findings in other ocular pathologies that can be confused with traumatic pathologies is important to make an adequate differential diagnosis. The aim of this article is to carry out a review of imaging findings of traumatic ocular injuries.
RESUMO
We present a case of an eight-month-old girl who was brought to the emergency department with bloody stools. An initial ultrasound reported a mass in the left iliac fossa that was further characterized by magnetic resonance imaging (MRI) as a hypervascular ovarian tumor. Prior to surgical resection of the tumor, abdominal arteriography with selective embolization and vessel occlusion was performed. Pathology reported epithelioid hemangioendothelioma of the left ovary. This condition has not been previously reported in girls. In this case report, we describe the ultrasound, MRI, and arteriographic findings with a histopathologic correlation of an adnexal tumor that is unknown in the pediatric female population until now.
RESUMO
El neumomediastino espontáneo es una condición clínica de baja incidencia. Se caracteriza por tener aire libre en el mediastino sin trauma asociado, y se considera un trastorno benigno y autolimitado. El diagnóstico se realiza por sospecha clínica y se confirma con imágenes diagnósticas. Esta entidad ha sido poco informada en la literatura nacional, y se considera que el probable subdiagnóstico se debe al poco conocimiento de sus características clínicas y epidemiológicas en nuestro medio. Se presenta una serie de 11 casos de neumomediastino espontáneo estudiados en dos instituciones de alta complejidad de Medellín, Colombia.
Spontaneous pneumomediastinum, a clinical condition with low incidence, is characterized by the presence of free air in the mediastinum without associated trauma, and it is considered a benign and self-limiting disorder. The diagnosis is made by clinical suspicion and is confirmed with diagnostic images. This entity has been little reported in the national literature, considering that the probable underdiagnosis is due to lack of knowledge of its clinical and epidemiological characteristics in our environment. A series of 11 cases of spontaneous pneumomediastinum in patients admitted to two institutions of high complexity in Medellin-Colombia are presented.
