Pneumosinus dilatans frontal en niña de 9 años. Presentación de un caso y revisión de la literatura

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.
