RESUMEN
El pneumosinus dilatans (PD) representa una enfermedad infrecuente en adultos, y verdaderamente excepcional en niños. Existen aproximadamente 100 casos descritos en adultos en la literatura, de los cuales menos de 10 han sido descritos en chicos con edades comprendidas entre los 12-16 años, y ninguno en niños. Se describe como una aireación anómala de un seno paranasal más allá del límite normal del hueso con mucosa normal. Puede producir alteraciones cosméticas o funcionales. Su etiología permanece siendo desconocida. Afecta fundamentalmente al seno frontal. Presentamos el caso de una niña de 9 años con diagnóstico de PD frontal desde los 3 años, intervenida quirúrgicamente por alteración cosmética relevante. La intervención quirúrgica fue practicada mediante abordaje endocraneal a través de incisión coronal con resultados cosméticos excelentes (AU)
Pneumosinus dilatans (PD) is a rare condition in adults and truly exceptional in children. There are approximately 100 reported cases in adults, with fewer than 10 in adolescents aged 12-16, and none in children. It is described as a benign airfilled expansion of a paranasal sinus beyond the normal osseous boundaries. It could result in cosmetic and functional complications. The precise etiology of the condition remains unknown. The frontal sinus is the most commonly affected. It is reported the case of a 9-year-old female diagnosed with PD frontalis at 3 years of age. She underwent surgery for significant cosmetic alterations. The surgical plan included an intracranial approach through coronal incision with excellent cosmetic results (AU)

BACKGROUND: The perception we have of our own body, called 'body image,' is crucial for self-awareness. Here, we evoked reproducible mental imagery of a postural illusion by intrasurgical electrostimulation of the central cortex. CASE REPORT: A 24-year-old patient experienced seizures involving vivid mental imagery of biomechanically impossible movements of the upper limb. A right precentral low-grade glioma was diagnosed. Awake surgery with intraoperative electrostimulation sensorimotor mapping was performed. Remarkably, the same mental representations of biomechanically impossible movements of the left upper limb were repeatedly elicited during stimulation of the central cortex. These eloquent areas were preserved, even though the precentral part of the knob of the hand was removed. After a transient monoplegia, the patient recovered and resumed a normal life which included playing the guitar. CONCLUSION: These mental experiences of a postural illusion generated by intraoperative stimulation could be related to neuroplasticity mechanisms induced by the slow growth of low-grade glioma within the knob of the hand. Such a functional reorganization may explain why this area was removed without permanent deficits. This perception of biomechanically impossible movements during surgery might be due to a transient disruption by stimulating the frontoparietal network involved in the coding of the body image.
