Tratamiento multidisciplinario en un niño afectado por un quiste dentígero / Multidisciplinaty treatment in a child with dentigerous cyst

Se presenta el caso clínico de un paciente que a los 7 años de edad fue remitido a la Clínica Estomatológica Provincial Docente Mártires del Moncada de Santiago de Cuba por presentar un quiste dentígero y displasia fibrosa monostótica. Desde entonces, y durante casi 10 años, el paciente ha sido atendido por un equipo multidisciplinario odontopediátrico, que ha seguido su evolución y ha aplicado diferentes protocolos diagnósticos y terapéuticos; estos últimos han incluido intervenciones quirúrgicas, rehabilitaciones protésicas, quimioterapia, entre otros. Por la complejidad del caso y la poca frecuencia con que aparecen asociadas ambas entidades clínicas en la infancia, se decidió comunicar este artículo al gremio odontológico nacional y extranjero.

The case report of a seven years old child who was referred to Mártires del Moncada Provincial Teaching Stomatological Clinic in Santiago de Cuba, who had a dentigerous cyst and monostotic fibrous displasia is presented. Since then, and almost during 10 years, the patient has been assisted by a multidisciplinary odontopediatric team, which has followed his clinical course and has applied different diagnostic and therapeutic protocols, including surgical procedures, prosthetic rehabilitations, chemotherapy, among others. Due to the case complexity and the frequency with which both clinical entities are associated in childhood, it was decided to publish this work for the national anf foreing odontological community.

Imaging diagnosis of monostotic fibrous dysplasia in thoracic and lumbar spine vertebrae / 华中科技大学学报（医学）（英德文版）

The X-ray radiograph, CT scan and MRI appearance of 5 patients with pathologically proven fibrous dysplasia in thoracic and lumbar spine vertebrae were retrospectively analyzed. Plain radiographs, CT scans and MR images showed the presentation of eccentric lesion with intact cortex bone and marginal sclerosis in vertebral bodies without involvement of vertebral appendix and extraosseous soft tissue. The lesion masses were round (one being oval-shaped) and radiolucent in plain radiographs and CT scans. Homogeneous long signal was observed on T1 weighted image and strongly enhanced when gadolinium was administered. On T2 weighted MRI, short signal was found in the anterior part of the mass, long signal in the posterior part, and short and slight long signal in the middle part, without partitioning and laminating change. There was a good correlation between radiological features and surgical findings. These findings may be useful to diagnose fibrous dysplasia in spine.
