RESUMO

El tumor inflamatorio de Pott (PPT) es una osteomielitis del hueso frontal con un absceso subperióstico concomitante, principalmente secundario a sinusitis frontal complicada. Es infrecuente, pero puede tener consecuencias fatales debido a su alta asociación con complicaciones intracraneales. Presentamos el caso de una escolar de 7 años sin antecedentes, que consulta en el Servicio de Urgencia por un cuadro de 5 semanas de rinorrea mucopurulenta derecha y aumento de volumen frontal progresivo, habiendo recibido antibioticoterapia sin respuesta. Se realizan neuroimágenes que confirman el diagnóstico de rinosinusitis aguda fronto-etmoidal complicada con absceso subperióstico frontal compatible con PPT, asociado a un absceso epidural. Se manejó con antibiótico endovenoso prolongado y aseo quirúrgico mediante craniectomía por abordaje bi-coronal con drenaje de ambas colecciones y reconstrucción de base de cráneo con colgajo de pericráneo, evolucionando favorablemente. El diagnóstico del tumor inflamatorio de Pott es clínico y radiológico, siendo el aumento de volumen frontal el signo cardinal. La tomografía computarizada es útil para establecer el diagnóstico diferencial con otras entidades y la resonancia magnética permite con mayor sensibilidad y especificidad detectar complicaciones intracraneales. El tratamiento es médico y quirúrgico mediante antibioticoterapia endovenosa y aseo quirúrgico oportuno.


Pott's inflammatory tumor is an osteomyelitis of the frontal bone with a concomitant subperiosteal abscess, mainly secondary to complicated frontal sinusitis. It is rare entity but may have fatal consequences due to its high association with intracranial complications. We present the case of a healthy 7-year-old girl who presented to the emergency department with a 5-week history of mucopurulent right rhinorrhea and progressive forehead swelling without response to oral antibiotic therapy. Neuroimaging confirms the diagnosis of acute frontoethmoidal rhinosinusitis complicated with frontal subperiosteal abscess compatible with PPT and an epidural abscess. She received prolonged intravenous antibiotics for six weeks and surgical treatment with craniectomy by bi-coronal approach with drainage of both collections and reconstruction of the skull base with pericranial flap, progressing favorably. The diagnosis of Pott's inflammatory tumor is clinical and radiological. The increased frontal volume is the cardinal sign, and computed tomography is the image of choice, which is also helpful in establishing the differential diagnosis with other entities. Magnetic resonance imaging is practical, given its greater sensitivity and specificity to detect intracranial complications. Treatment is imperative and is based on adequate antibiotic therapy and prompt surgical debridement.
